v0.7.4 — Reauth, diagnostics download & VRF tuning

What's new since v0.6.0

Features

• Reauth flow, options & diagnostics download: reconfigure credentials without re-adding, per-entry options, and downloadable diagnostics with device grouping.
• VRF-tuned diagnostics: outdoor power/energy sensors and guest use-limits.

Testing & CI

• Full pytest suite covering config/reauth flows, coordinator, and diagnostics, wired into CI.
• Hardened GitHub Actions workflows; bumped actions/checkout, actions/setup-python, and github/codeql-action.

Docs

• Added security policy with private vulnerability reporting.

Full changelog: v0.6.0...v0.7.4

v0.6.0 — Outdoor VRF health diagnostics & warnings

Read the outdoor machine like a service engineer

The integration now polls each outdoor unit's cycle-monitoring data and turns the raw refrigerant readings into an actionable health status.

New "Outdoor unit" device per condensing unit:

• Telemetry sensors: outside / discharge / inverter (IPM) temperature, high & low pressure (bar), compressor current, frequency and run-hours.
• Derived engineer's metrics: condensing & evaporating temperature, condenser approach (a dirty-coil / cleaning indicator) and suction superheat.
• Health status sensor — OK / Warning / Alert — that flags a dirty condenser coil, high discharge temperature, inverter overheating, likely low charge, or a communication fault, with a plain-language issues list you can show on a dashboard.
• Compressor-running, communication-error and maintenance-required binary sensors.

Per-unit warnings you can automate on

Every indoor/EHS/ERV unit now has Fault and Filter binary sensors (problem device class). Point a Home Assistant automation at them to get a notification when a unit errors or when its filter-cleaning alarm trips.

All thresholds are conservative and advisory — this highlights "worth looking at", not a replacement for a technician with gauges. R410A (DVM S/Plus). Verified against live site data.

v0.5.1 — ERV tempering status sensors

Adds read-only Setpoint and Operating mode sensors for energy-recovery ventilators.

Note: the ERV Plus does temper incoming air, but investigation of the DMS control protocol confirmed its mode and setpoint are driven by the connected system — the DMS provides no control path for them. Exposing a thermostat would have created non-functional controls, so these are surfaced as read-only sensors instead.

v0.5.0 — Instant feedback & ERV sensors

Faster UI feedback

Control commands (power, mode, temperature, remote lock, fan, etc.) now update the entity immediately instead of waiting for the next 30-second poll:

• The commanded value is shown optimistically and held until the DMS confirms it.
• Two fast follow-up polls (~4s and ~10s) fetch the real state right after a command, so it confirms within seconds and a rejected command surfaces quickly.

Energy-recovery ventilator sensors

ERV (pluserv) units now expose proper sensor entities — CO₂, outdoor temperature, air temperature, and intake-air temperature — created only when the unit actually reports them. These get long-term history and can drive automations (e.g. boost ventilation on high CO₂).

Update via HACS to get instant feedback if you were on v0.4.x.

v0.4.2 — HACS brand icon

Adds a local brand icon (custom_components/samsung_dms/brand/) so all HACS validation checks pass (9/9). The integration now validates cleanly for the HACS default store.

No functional changes.

v0.4.1

Version bump. No functional changes since v0.4.0.

v0.4.0 — Remote lock & schedule sensor

• Remote lock switch per unit: turn on to disable the physical wall remote (guests can't change settings), off to re-enable. The raw DMS state (true/false/level1) is exposed as an attribute.
• Schedule active binary_sensor per unit: shows whether a DMS schedule is currently driving the unit (read-only; schedules are still managed on the DMS).

Both group under each unit's existing device alongside its climate/water_heater/fan entity.

v0.3.0 — Swing control & EHS space heating

• Swing control on AC climate entities: off / vertical / horizontal / both. Each unit only advertises the vanes it actually has (vertical when the unit reports a UD vane, horizontal when useLRSwing is set).
• EHS space heating: the water-out (leaving-water) side of EHS units is now a second climate entity — heat/cool, leaving-water setpoint, per-mode limits — grouped under the same device as the existing hot-water water_heater.

v0.2.0 — EHS water heater & ERV fan

Units are now routed to the correct Home Assistant platform based on their DMS type:

• EHS / hydro units (e.g. "ACS") become a water_heater: on/off, supply mode (standard/power/force), tank target & current temperature, and away mode.
• Energy-recovery ventilators (pluserv, e.g. "Recuperatore") become a fan: on/off, speed (low/mid/high/turbo), and ventilation mode as a preset (auto/erv/normal/sleep).
• Indoor AC units remain climate entities.

Classification uses the tree-view metadata; anything unrecognised falls back to a climate entity so no unit is ever dropped.

v0.1.1 — Real unit names

Entities now use the room labels configured on the DMS (e.g. "Reception", "301", "Cucina 507") instead of the internal address, and expose the unit's model type and firmware version. unique_id remains address-based, so renaming a unit on the DMS won't orphan the Home Assistant entity.
