EcoFlow Cloud – Home Assistant Integration

Disclaimer: This software is not affiliated with or endorsed by EcoFlow in any way. It is provided "as-is" without warranty or support, for the educational use of developers and enthusiasts. Use at your own risk.

Real-time monitoring and control of EcoFlow power stations via MQTT. Supports two connection modes:

App Login (email + password) — MQTT telemetry + JSON SET control for all devices including Delta 3
Developer API (Access Key + Secret Key) — REST API for device list and credentials (SET commands blocked for D361 series)

Actively tested with: EcoFlow Delta 3 1500 (D361 series, App Login + MQTT JSON SET)

Installation via HACS

Click the button above or go to HACS → Integrations → ⋮ → Custom repositories
Add URL: https://github.com/windsurf/hassio-ecoflow-eu — category: Integration
Search for EcoFlow Cloud and click Download
Restart Home Assistant (full restart required — not just reload)
Go to Settings → Devices & Services → Add Integration → EcoFlow Cloud

Manual Installation

Download the latest release
Extract and copy custom_components/ecoflow_cloud/ to your HA config/custom_components/ directory
Restart Home Assistant (full restart — reload integration is not sufficient after code updates)

Important: Always do a full HA restart after updating this integration. The reload integration shortcut does not clear Python bytecode cache (.pyc) and may run the old code silently.

Getting Credentials

Option A — App Login (recommended for Delta 3 and newer devices)

Use your regular EcoFlow app email and password. No extra setup needed.

Option B — Developer API

Go to developer-eu.ecoflow.com and sign in
Click Become a Developer and wait for the approval email
Go to Security and create an Access Key + Secret Key

Setup

Step 1: Enter your device serial number and choose a connection method. Select Auto-detect (recommended) — Delta 3, newer PowerStream and other recent devices will use App Login automatically; older devices use the Developer API.

Step 2: Enter credentials for the chosen method.

Step 3 (App Login only): Optionally enter Developer API keys. For Delta 3 (D361) devices this has no effect on control — REST SET is blocked by EcoFlow for this series. Leave empty to skip.

Step 4: Automatic connection test — confirms login and shows which devices are on your account.

After setup, use the gear icon on the integration card to change credentials, add Developer API keys, or switch API mode.

How Control Works (Delta 3)

Confirmed via live protocol analysis (v0.2.22–v0.2.24): Delta 3 uses MQTT JSON SET with "from": "Android" in the payload.

Function	Channel	Notes
Real-time sensor data	MQTT push	`/app/device/property/{sn}` — pushed every ~3s (pd) or ~3-5 min (mppt)
Switch/number control	MQTT JSON SET	`"from":"Android"` required
REST API SET	Blocked	EcoFlow blocks D361/D362/D381/R641/R651 (code=1006)

SET command payload: {id, version:"1.0", sn, moduleType, operateType, from:"Android", params:{...}}

D361-Specific Behaviour (confirmed via live tests)

Feature	Behaviour
AC Charging pause (`chgPauseFlag`)	Not supported — command received (beep) but has no effect. `mppt.chgPauseFlag` never in telemetry.
LCD Brightness	Not controllable via MQTT — `lcdCfg brighLevel` received (beep) but no visible effect
Screen Timeout (`lcdCfg delayOff`)	Works — do not send `brighLevel=255` alongside it; D361 writes 65535 literally
AC Standby (`standbyTime` mod5)	Works — operateType must be `standbyTime`, not `standby`
MPPT keys update frequency	Every 3–5 minutes (not real-time), periodic full upload
`mppt.chgPauseFlag` in telemetry	Never pushed — not a supported state key on D361
`bms_emsStatus.sysChgDsgState`	Charge state indicator: 0=idle, 1=discharging, 2=charging
`pd.lcdOffSec = 65535`	Sentinel value for "Never" (not 0)
`pd.acAutoOutPause`	Always 0 on D361 -- never pushed via telemetry. Bypass state unavailable. SET command works (relay confirmed).
`mppt.cfgAcEnabled`	Updates 2s before `pd.acEnabled` and `inv.cfgAcEnabled` on AC Output toggle

How It Works

EcoFlow Cloud (App Login mode — recommended for Delta 3)
 |
 +-- REST API (App Login — Email + Password)
 |   +-- /auth/login                    -> token + userId
 |   +-- /iot-auth/app/certification    -> MQTT credentials (renewed every 10 min)
 |
 +-- MQTT TLS :8883  mqtt-e.ecoflow.com
     subscribe: /app/device/property/{sn}                  (telemetry push)
     set:       /app/{userId}/{sn}/thing/property/set       (JSON SET commands)
     set_reply: /app/{userId}/{sn}/thing/property/set_reply (command ACK)
     get:       /app/{userId}/{sn}/thing/property/get       (GET-ALL keepalive every 20s)

SET command payload:
  {"id":<seq>, "version":"1.0", "sn":"<SN>", "moduleType":<n>,
   "operateType":"<cmd>", "from":"Android", "params":{...}}

REST API: used only for MQTT credential retrieval. SET commands blocked for D361 series.

MQTT push is the primary data source. Telemetry frequency varies by module:

pd.* keys: every ~3 seconds
mppt.* keys: every ~3-5 minutes (full upload), ~2 minutes (incremental)
bms_emsStatus.* / bms_bmsStatus.*: every ~3 seconds

MQTT credentials are renewed every 10 minutes (periodic recertification) — this is normal behaviour and does not interrupt telemetry.

Changelog

v0.3.10 -- Climate + Smart Home Panel + PowerKit + PowerOcean

Climate devices

Wave 3 (mobile AC with battery, placeholder SN: KT3): protobuf cmdFunc=254 family, 25 sensors covering ambient temperature/humidity, supply air, condensate level, operating mode, battery, AC/PV/DC power. Read-only in this release -- foxthefox documents //cmd markers but no SET implementation.
Glacier 55 (dual-zone portable refrigerator, placeholder SN: BX55): protobuf cmdFunc=254, 22 sensors + 4 switches (child lock, simple mode, temp alert, beep) + 6 numbers (left/right setpoints as floats, max/min SOC, standby, battery protect) + 1 select (cooling mode Eco/Max/Sleep). First device using the new _ff() IEEE 754 float helper for SET commands.

Smart Home Panel

SHP1 / Smart Home Panel (SH10): JSON SET protocol with operateType: TCP. 45 sensors (per-circuit power/current/name + system stats + EPS + thresholds)
- 13 switches (12 channel-controls + EPS mode) + 2 numbers (backup discharge thresholds). Activates the SH10 stub registered in v0.3.9.
SHP2 / Smart Home Panel 2 (SH20): protobuf cmdFunc=12 (ProtoPushAndSet). 5 sensor stubs registered. Full decoder routing for cmdFunc=12 lands in v0.4.0 -- entities will activate automatically once decoder support is added.

PowerKit (modular off-grid system, placeholder SN: M106)

Read-only by design -- foxthefox documents only GET commands. ~30 core sensors selected from 215+ telemetry fields across submodules: bp1 (primary battery), bp2, bbcin/bbcout (DC-DC), iclow/ichigh (chargers), ldac/lddc (load AC/DC), kitscc (solar), wireless. Uses dotted prefix keys (bp1.soc, ldac.outWatts).

PowerOcean / PowerOcean Plus / PowerOcean Fit (residential energy storage)

Tesla Powerwall / Sessy / Sonnen-class home battery + hybrid inverter. v0.3.10: SN-prefix detection (PO11/PO31/POFI placeholders) + 22 sensor stubs covering battery/EMS/PCS/grid safety. Full protobuf decoder for cmdFunc=96 (JTS1_EMS_HEARTBEAT) and cmdFunc=254/cmdId=32 (EnergyTotalReport) coming in v0.4.0.

Decoder routing

decode_proto_telemetry() now accepts a device_model parameter to disambiguate cmdFunc=254/cmdId=21 telemetry between device families that share field numbers but differ in semantic meaning. Fixes a field 777 conflict between Wave 3 (powGetSelfConsume in W) and Glacier 55 (inputVolt777 in V) -- both would have produced wrong sensor values on the same-numbered field.

SN-prefix registry updates

KT3 (Wave 3), BX55 (Glacier 55), M106 (PowerKit)
PO11 / PO31 / POFI (PowerOcean variants)
Total registered models: 35 (was 30 in v0.3.9)

Note on placeholder SN prefixes

Several new devices (Wave 3, Glacier 55, PowerKit, PowerOcean variants) ship with placeholder SN prefixes inferred from foxthefox naming patterns. If your device is misdetected, please open a GitHub issue with your full SN string -- prefixes will be corrected and a v0.3.10.x patch released.

v0.3.9 -- Stream AC family (protobuf grid-tied inverter) + Delta 3 Plus/Max

Stream AC / AC Pro / Ultra -- protobuf telemetry + control

New device family: grid-tied micro-inverter with optional 1920Wh LFP battery
Protobuf protocol (cmdFunc=254) with IEEE 754 float decoding for wire type 5
Latest-quotas keepalive (foxthefox pattern): minimal setMessage ping every 15s to keep DisplayPropertyUpload telemetry flowing
Model-specific entity sets (v0.3.9 split):
- Stream AC (BK?1Z): pure inverter -- 18 sensors, 0 switches, 2 numbers
- Stream AC Pro (BK31Z): inverter + battery + PV2 -- 27 sensors, 2 switches, 5 numbers
- Stream Ultra (BK11Z): inverter + battery + 4xPV -- 29 sensors, 2 switches, 5 numbers
Paired SOC commands (max/min must be sent together) via coordinator lookup
ConfigWriteAck (cmdId=18) decoder for command confirmation
New diagnostic sensors (disabled by default): feedGridMode, stormPatternEnable, stormPatternOpenFlag -- community reverse-engineering aid

Delta 3 Plus (D362) + Delta 3 Max (D381)

Full device support added (previously fell back to diagnostic mode)
Command set identical to Delta 3 1500 -- all 18 commands reused
Plus adds 11 PV2 MPPT input sensors (second solar channel)
Max adds 16 diagnostic sensors (DCDC, LLC, PFC, 12V aux, PV voltage refs)
All new sensors disabled by default until live telemetry confirms dotted prefix

SN prefix registry updates

BK, BK31, BK11 for Stream AC family
SH10, SH20 for Smart Home Panel 1/2 (prefix only, entities TBD in future release)

v0.3.7 -- River 3/3 Plus + DPU showFlag + AC DSG fix

New devices: River 3 (R641) and River 3 Plus (R651):

Gen 3 protocol (cmdFunc=254) — same command envelope as Delta Pro 3
New device file: devices/river3.py with flat quota keys from community MQTT data
20 sensors: SOC, SOH, total power in/out, per-port power (AC, USB, Type-C, 12V, PV), temperatures, settings readback
6 switches: AC Output, DC 12V, X-Boost, Beep, Output Memory, Energy Backup
7 numbers: Max/Min SOC, Device/Screen/AC standby, AC charging power, Solar max current
Source: foxthefox/ioBroker.ecoflow-mqtt river3plus.md (community-confirmed via live MQTT)

Switch is_on fix for River 3 flow keys:

River 3 uses 0=off, 2=on for flow status keys (not 0/1 like other devices)
Changed is_on from int(val) == 1 to int(val) != 0 — covers both conventions safely

DPU switches now use telemetry-confirmed state instead of optimistic updates:

AC Output (bit 2), DC Output (bit 5), Battery Heating (bit 1) read actual state from showFlag bit field
Removed optimistic=True from these three switches — state updates arrive via MQTT telemetry push
Battery Heating moved from bmsModeSet quota key to showFlag with inverted=True (bit 1: 0=enabled, 1=prohibited)

New named constants in delta_pro_ultra.py:

SHOW_FLAG_BIT_HEAT = 1, SHOW_FLAG_BIT_AC = 2, SHOW_FLAG_BIT_DC = 5
Replaced magic numbers in switch definitions with named constants
Removed unused extract_show_flag_bit() helper function (logic is inline in is_on property)

AC DSG combined command: read current values from coordinator:

YJ751_PD_AC_DSG_SET sends enable + xboost + freq in one command
Now reads actual acXboost and acOutFreq from coordinator data instead of 255 sentinel

Device count: 22 devices total (20 previous + River 3 + River 3 Plus). All with full control.

v0.3.6 -- Delta Pro Ultra full implementation (cmdCode protocol)

New device: Delta Pro Ultra (DGEB) — fully implemented:

New cmdCode protocol: YJ751_PD_* command codes instead of moduleType/operateType
New prefixed quota keys: hs_yj751_pd_appshow_addr.*, hs_yj751_pd_app_set_info_addr.*, hs_yj751_pd_backend_addr.*
12 SET commands implemented via REST PUT and MQTT
~45 sensors: SOC, total power in/out, per-port AC power (6 ports), DC/USB/Type-C, solar HV/LV, V/A per port
6 switches: AC Output, X-Boost, DC Output, Battery Heating, 4G, AC Always-On + Energy Management (read-only)
8 numbers: Max/Min SOC, AC/DC/Device standby, Screen standby, AC charging power, POWER IN/OUT charging power + AC Always-On Min SOC, Backup Reserve SOC
Source: official EcoFlow developer docs (developer-eu.ecoflow.com/us/document/deltaProUltra)

DPU showFlag bit field parsing:

AC Output reads bit 2, DC Output reads bit 5 from showFlag integer
New show_flag_bit field on SwitchDescription for bit extraction in is_on

Additional DPU entities:

Energy Management switch (read-only)
AC Always-On Min SOC number
Backup Reserve SOC number (read-only)
Operating Mode select (Default/Self-powered/Scheduled/TOU)

Fixes:

Delta 3 Plus and Delta 3 Max added to select.py model registry (prevented crash)
Delta Pro 3 added to select.py model registry
AC_DSG combined command uses 255 sentinel to preserve current xboost/freq values

New API method: set_quota_cmdcode():

Added to both EcoFlowAPI and EcoFlowPrivateAPI for cmdCode-based SET commands
REST: PUT /iot-open/sign/device/quota with {sn, cmdCode, params}
MQTT: {id, version:"1.0", cmdCode:"YJ751_PD_*", params:{...}}

Platform updates for cmdCode routing:

switch.py: new dpu_cmd_code + dpu_cmd_params fields, cmdCode publish path (Priority 2.6)
number.py: new dpu_cmd_code + dpu_cmd_param_key fields, cmdCode publish path (Priority 2.6)
button.py: DPU registered (no buttons in DPU docs)
sensor.py: ~45 DPU sensors registered across 3 namespaces

Device count: 20 devices total (19 previous + Delta Pro Ultra). All with full control.

v0.3.5 -- Repository rename + device profile verification

Repository renamed: hassio-ecoflow-eu-delta3 → hassio-ecoflow-eu

All URLs updated: manifest.json, README badges, HACS links, push script
GitHub redirects ensure existing installations continue to work

Device profile verification against official EcoFlow developer docs:

Verified all 10 documented devices against developer-eu.ecoflow.com
9 of 10 devices fully functional, 1 (Delta Pro Ultra) registry-only
All core functions (AC/DC control, charge/discharge limits, X-Boost) confirmed correct
Protocol formats validated: Gen 1 (TCP), Gen 2 (moduleType), Gen 3 (cmdFunc=254), Protobuf

Delta Pro Ultra: registry only in v0.3.5 (cmdCode protocol — implemented in v0.3.6)

19 devices total. All with full control (except Delta Pro Ultra — registry only).

v0.3.4 -- Protobuf telemetry decoder (Smart Plug + PowerStream sensors live)

Protobuf telemetry decoder:

Binary MQTT messages (protobuf) are now decoded and fed into the coordinator
Previously these messages were logged but discarded — sensors never received data
Generic decoder in proto_codec.py: parses EcoFlow envelope → extracts header (cmd_func, cmd_id) → maps pdata fields to coordinator keys

Smart Plug (SP10) — now full control (was commands-only):

5 sensor entities now receive live data: Power, Voltage, Current, Temperature, Frequency
Heartbeat telemetry (WnPlugHeartbeatPack, cmdFunc=2) decoded with 11 field mappings
Promotes Smart Plug from commands-only to full control (16 devices, all full control)

PowerStream — protobuf sensor path enabled:

inverter_heartbeat (cmdFunc=20) decoded with 56 field mappings
Covers all solar, battery, inverter, LLC, and system sensors
Works alongside existing JSON path — protobuf data merges into coordinator

Infrastructure:

decode_proto_telemetry() in proto_codec.py: header extraction + field mapping per cmdFunc
_parse_fields(): generic protobuf wire-format parser (varint, LEN, fixed32, fixed64)
_extract_header(): EcoFlow envelope parser (pdata, src, dest, cmd_func, cmd_id)
Field mapping tables: _PS_HEARTBEAT_FIELDS (56 fields), _SP_HEARTBEAT_FIELDS (11 fields)
Extensible: add new device decoders by adding a cmdFunc entry to _HEARTBEAT_DECODERS

Output Memory (D361) — state retrieval at startup:

pd.outputMemoryEn is not included in latestQuotas or regular telemetry push
Added getOutputMemory JSON GET to the MQTT init sequence (step 5)
Switch now enabled by default with optimistic=True for immediate toggle feedback
Initial state loaded from device reply at startup

16 devices total, all with full control.

Delta Pro 3 (DGEA) — full device profile (17th device):

New command protocol: {sn, cmdId:17, cmdFunc:254, dest:2, dirDest:1, dirSrc:1, needAck:true, params:{...}}
Flat quota keys (no pd./mppt. prefix): enBeep, cmsMaxChgSoc, flowInfoAcHvOut, etc.
14 sensors: charge limits, standby timers, power settings, generator SOC thresholds
9 switches: Beep, X-Boost, AC HV/LV Output, DC 12V, Energy Backup, Generator Auto-Start, GFCI, AC Energy Saving
13 numbers: Max/Min SOC, AC/DC/Device standby times, LCD brightness, AC charging power, solar current limits, generator SOC
1 button: Power Off
DP3 command dispatch added to switch.py, number.py, button.py (Priority 2.5)
Device profile: devices/delta_pro_3.py with 26 quota keys + 26 command keys + envelope constants
Source: Official EcoFlow Developer Platform docs (developer-eu.ecoflow.com/us/document/deltaPro3)

17 devices total (16 original + Delta Pro 3). All with full control.

Delta 3 Plus (D362) + Delta 3 Max (D381) — same protocol as D361:

Registered in sensor, switch, number, button registries using D361 definitions
Same JSON MQTT SET protocol, same dotted quota keys, same commands
Already in device registry (SN prefix detection) and REST_SET_BLOCKED list

19 devices total. All with full control.

v0.3.3 -- D361 Beep Sound fix + Bypass optimistic + tested live

Beep Sound fix (D361) -- confirmed working via live test:

Added inverted=True -- mppt.beepState=1 means quiet mode ON (sound OFF)
Switch now correctly shows ON when sound is actually ON, OFF when muted
Command confirmed: quietMode enabled=0 turns sound ON, enabled=1 turns sound OFF

Bypass (D361) -- confirmed working via live test:

Added optimistic=True -- state updates immediately after toggle
pd.acAutoOutPause is always 0 in D361 telemetry (confirmed: does not change even via app)
Command works: ack=1, relaySwitchCnt increments, app confirms state change
Enabled by default (was disabled)

UPS Mode (D361) -- diagnostic only:

openUpsFlag is firmware-controlled (AC pass-through based on battery state + AC input)
Command accepted (ack=1) but not a user-toggleable switch in the EcoFlow app
Kept as disabled-by-default diagnostic entity

v0.3.2 -- Glacier buttons + Smart Plug + PowerStream sensor fix

Glacier (BX11) — 3 buttons added:

Make Small Ice, Make Large Ice, Detach Ice (new button platform)

Smart Plug (SP10) — device profile + commands (16th device):

5 sensors: Power, Voltage, Current, Temperature, Frequency
1 switch: Power on/off
2 numbers: LED Brightness (0-1023), Max Power (0-2500W)
Uses protobuf binary protocol (cmdFunc=2, same envelope as PowerStream)
NOTE: sensor telemetry requires protobuf decoder in MQTT handler (commands work, sensors pending)

PowerStream sensor scaling fix:

All PowerStream sensors now correctly scaled: deciWatts→Watts, deciVolts→Volts, deciAmps→Amps, deciCelsius→Celsius, deciHz→Hz
Output Limit number uses state_scale=0.1 so slider and sensor stay in sync

Bug fix: bms_slave comma-decimal (v0.2.25 backlog):

Sensors receiving comma-decimal strings (e.g. bms_slave.diffSoc = "1,11") now parse correctly instead of falling back to string state
Affects bms_slave.diffSoc, bms_slave.cycSoh, bms_bmsStatus.diffSoc, bms_bmsStatus.cycSoh on Delta 3 1500

Infrastructure:

New button platform (button.py) with EcoFlowButtonDescription + JSON command dispatch
Added state_scale to EcoFlowNumberDescription for numbers where raw MQTT value differs from display unit
3 Smart Plug protobuf command builders in proto_codec.py (switch, brightness, max_watts)

16 devices total. 15 with full control, 1 commands-only pending sensor decoder (Smart Plug).

v0.3.1 -- Gen 1 full control + PowerStream, Glacier, Wave 2

Gen 1 devices now have switches, numbers, and selects:

Delta Pro (DAEB) -- 6 switches, 6 numbers, 4 selects
Delta Max (DCAB) -- 7 switches, 5 numbers
Delta Mini (DAAZ) -- 4 switches, 3 numbers, 4 selects
River Max (R601) -- 5 switches, 1 number, 3 selects
River Pro (R602) -- 7 switches, 1 number, 3 selects
River Mini (R501) -- 2 switches, 1 number

Gen 1 TCP commands (moduleType=0, operateType=TCP, params.id) work through the existing _publish() infrastructure -- no protocol changes needed.

New device profiles:

PowerStream / 600W / 800W (HW51, HW52, BKW) -- 21 sensors + 1 switch + 4 numbers + 1 select (full control, protobuf binary protocol)
Glacier (BX11) -- 21 sensors + 3 switches + 3 numbers (full control, JSON protocol)
Wave 2 (KT21) -- 13 sensors + 1 number + 4 selects (full control, JSON protocol)

Glacier and Wave 2 use JSON protocol (moduleType=1) -- same infrastructure as Gen 1/Gen 2. PowerStream uses protobuf binary protocol with pure-Python encoder -- no protobuf library dependency.

Infrastructure:

Added proto_builder_sn to switch/number/select descriptions for protobuf binary commands (PowerStream)
Added cmd_params_coord_fn to EcoFlowNumberDescription for commands needing sibling entity state (Glacier temp sync)
Dispatch priority in all _publish(): REST API > Proto binary > JSON MQTT
6 PowerStream protobuf command builders in proto_codec.py

15 devices total. All 15 with full control.

v0.3.0 – Multi-device architecture + 12 device profiles

Architecture: multi-device support

Added device registry (devices/registry.py) with SN prefix to model mapping for 27+ EcoFlow devices
Device model is now auto-detected from serial number at setup time
Entity descriptions are dispatched per device model -- platform files (sensor.py, switch.py, number.py, select.py) load the correct description tuple based on detected device
DeviceInfo (model name in HA UI) is now dynamic instead of hardcoded
All entity unique_ids unchanged -- zero breaking changes for existing Delta 3 1500 users
Integration name updated from "EcoFlow Cloud (EU Delta 3)" to "EcoFlow Cloud"

Gen 2 devices -- full control (sensors + switches + numbers + selects):

Delta 3 1500 (D361) -- 185 sensors, 13 switches, 9 numbers, 5 selects
Delta 2 (R331) -- 46 sensors, 8 switches, 6 numbers, 5 selects
Delta 2 Max (R351) -- 68 sensors, 7 switches, 6 numbers, 3 selects (dual solar, dual slave)
River 2 (R621) -- 32 sensors, 5 switches, 4 numbers, 5 selects
River 2 Max (R631) -- 32 sensors, 5 switches, 4 numbers, 5 selects
River 2 Pro (R622) -- 30 sensors, 3 switches, 3 numbers, 5 selects

Gen 1 devices -- read-only sensors (TCP command protocol not yet supported):

Delta Pro (DAEB) -- ~57 sensors incl. dual slave + energy counters
Delta Max (DCAB) -- ~56 sensors incl. dual slave + energy counters
Delta Mini (DAAZ) -- ~40 sensors incl. energy counters
River Max (R601) -- ~38 sensors incl. slave + energy counters
River Pro (R602) -- ~32 sensors incl. slave + energy counters
River Mini (R501) -- ~17 sensors incl. energy counters

Device detection (SN prefix mapping):

Delta series: D361, D362, D381, DGEA, DGEB, DAEB, R331, R351, DCAB, DAAZ
River series: R641, R651, R621, R631, R622, R601, R602, R501
PowerStream: HW51, HW52, BKW
Smart Plug: SP10
Climate: BX11, KT21

v0.2.25 – Slave battery sensors + Bypass fix

Added: Slave battery sensors (delta3_1500.py, sensor.py)

Added 35 sensors for the slave battery, confirmed present via live MQTT telemetry
Primary sensors enabled by default: SOC, SoH, voltage, current, temperature, remaining capacity, input/output power, charge cycles
Diagnostics disabled by default: cell temperatures, cell voltages, cumulative capacity/energy, internal resistance, round-trip efficiency, deep discharge count, error codes
Keys follow bms_slave.* prefix, units/scale identical to main battery bms_bmsStatus.*
bms_slave.diffSoc and bms_slave.cycSoh arrive as comma-decimal strings from device firmware

Fixed: Bypass switch state (switch.py)

Removed inverted=True from bypass switch -- pd.acAutoOutPause is always 0 on D361, never pushed via telemetry
Switch now shows OFF consistently (correct: bypass is inactive by default)
SET command (bypassBan mod1) confirmed working -- pd.relaySwitchCnt increments on each toggle
State feedback remains unavailable on D361; entity stays disabled by default

Investigated: Beep Sound switch

Confirmed correct: mppt.beepState=1 means sound ON, switch shows ON
If switch shows ON: device beep is actually enabled -- turn off in app or via HA

MQTT telemetry analysis (this release)

Confirmed via live MQTT listener: pd.acAutoOutPause never changes (Bypass state unavailable)
Confirmed: mppt.beepState is authoritative for beep state; pd.beepMode is static on D361
Confirmed: all three keys update on AC Output toggle: mppt.cfgAcEnabled (first), then inv.cfgAcEnabled and pd.acEnabled (~2s later)
bms_slave.* full telemetry confirmed: all primary keys arrive in latestQuotas and periodic push

v0.2.24 – AC Standby fix + AC Charging read-only + UPS Mode + switch corrections

Fixed: AC Standby Time operateType (select.py)

Fixed: AC Output Standby Time select sent operateType="standby" — device ignored it (4 hr never changed)
Correct operateType is "standbyTime" mod5 with standbyMins — confirmed via live test on D361 1500
Screen Timeout: removed brighLevel=255 from lcdCfg command — D361 writes 65535 literally when sent as keep-current; only delayOff is now sent

Fixed: AC Charging switch — made read-only (switch.py)

AC Charging switch now read-only: cmd_params=None, cmd_operate="", disabled by default
Root cause: confirmed via live test — acChgCfg chgPauseFlag command is received (beep) but has no effect on D361
mppt.chgPauseFlag is never pushed in D361 telemetry and does not exist in the D361 protocol schema
The switch was in an unknown/unavailable state permanently — now explicitly marked as not actionable
Use inv.inputWatts > 0 or bms_emsStatus.sysChgDsgState == 2 to detect active charging

Added: UPS Mode switch (switch.py)

Added ups_mode switch on bms_emsStatus.openUpsFlag — state key confirmed in D361 telemetry
Command: mod2 upsConfig {openUpsFlag: 1/0} — effect on D361 unconfirmed, disabled by default

Improved: Bypass and Output Memory comments (switch.py)

Both entities documented as "ACK only — no telemetry feedback on D361; state unknown"

D361 protocol findings documented (this release)

mppt.* keys update every 3-5 minutes — not real-time; pd.* updates every ~3s
pd.lcdOffSec = 65535 is the "Never" sentinel (not 0)
bms_emsStatus.sysChgDsgState: 0=idle, 1=discharging, 2=charging — reliable charge state indicator
Full restart required after code update — reload integration does not clear .pyc cache

v0.2.23 – Realtime telemetry fix + AC Charging Speed sync + entity corrections

Critical fix: typeCode mapping in coordinator

Fixed: all telemetry sensors never updated in HA without opening the EcoFlow app
Root cause: D361 sends telemetry pushes with short typeCode names (pdStatus, mpptStatus, invStatus) — coordinator was storing them as pdStatus.* instead of pd.*
Added typeCode → module prefix mapping: pdStatus→pd, mpptStatus→mppt, invStatus→inv, bmsStatus→bms_bmsStatus, emsStatus→bms_emsStatus, bmsInfo→bms_bmsInfo

AC Charging Speed (cfgChgWatts=255 sentinel)

Fixed: AC Charging Speed slider showed 255W in HA after every keepalive GET-ALL (every 20s)
Root cause: device always echoes cfgChgWatts=255 (sentinel meaning "keep current value") in latestQuotas reply
Coordinator now filters 255 from quotaMap; real values still arrive via telemetry push

AC Charging switch — chgWatts sentinel

Fixed: AC Charging switch sent chgWatts=255 with every toggle, writing 255W as the actual charge speed
Now sends only chgPauseFlag — device keeps current charge speed when chgWatts is omitted

Entity corrections

Backup Reserve switch: state_key corrected to pd.watchIsConfig (was pd.bpPowerSoc)
Battery Protection SOC: removed — duplicate of Min Discharge Level (same key + command)
4 standby/timeout sliders moved from number.py to select.py with human-readable options

New entities (68 sensors + 4 selects)

Added 68 new sensors (all disabled by default): extended BMS, EMS, MPPT, PD, INV telemetry keys
Added selects: Screen Timeout, Unit Standby Time, AC Output Standby Time, DC 12V Standby Time

v0.2.22 – Major: MQTT JSON control working for Delta 3 (protocol analysis)

Breakthrough: Delta 3 uses JSON MQTT SET with "from": "Android" — REST API returns code=1006 for D361
Fixed all switch/number command parameters from protocol analysis
Added Output Memory, Backup Reserve switch, Backup Reserve SOC, Connection Mode sensor
REST SET auto-skipped for D361/D362/D381/R641/R651 by SN prefix

v0.2.11–v0.2.21

v0.2.21: Hybrid Mode — REST API SET via Developer API; HMAC signing corrected
v0.2.20: manifest.json key order; brand/icon.png; GitHub Actions checkout@v5; enBeep dataLen=2
