Component review from DrZzs

Sonoffs can work with Home Assistant without changing the Firmware!

There is another great component by @peterbuga, that works with cloud servers.

Thanks to @beveradb and @mattsaxon for researching the local Sonoff protocol.
Thanks to @michthom and @EpicLPer for researching the local Sonoff Camera protocol.

Tested Devices

Almost any single or multi-channel Switch working in the eWeLink application will work with this Integration even if it is not on the list.

Tested (LAN and Cloud)

These devices work both on a local network and through the cloud.

Tested (only Cloud)

These devices only work through the cloud!

Tested ZigBee (only Cloud)

  • Sonoff ZigBee Bridge - turn on for pairing mode
  • SONOFF SNZB-01 - Zigbee Wireless Switch
  • SONOFF SNZB-02 - ZigBee Temperature and Humidity Sensor
  • SONOFF SNZB-03 - ZigBee Motion Sensor
  • SONOFF SNZB-04 - ZigBee Wireless door/window sensor

Tested Cameras (only LAN)

Maybe other eWeLink cameras also work, I don’t know.

Installation

HACS > Integrations > Plus > SonoffLAN

Or manually copy sonoff folder from latest release to custom_components folder in your config folder.

Configuration

Configuration > Integrations > Add Integration > Sonoff

If the integration is not in the list, you need to clear the browser cache.

You can setup multiple integrations with different ewelink accounts.

Important. If you use the same account in different smart home systems, you will be constantly unlogged from everywhere. In this case, you need to create a second ewelink account and share your devices or home with it.

Issues

Before posting new issue:

  1. Check the number of online devices on the System Health page
  2. Check warning and errors on the Logs page
  3. Check debug logs on the Debug page (must be enabled in integration options)
  4. Check open and closed issues
  5. Share integration diagnostics (supported from Hass v2022.2):
  • All devices: Configuration > Integrations > Sonoff > 3 dots > Download diagnostics
  • One device: Configuration > Devices > Device > Download diagnostics

There is no private data, but you can delete anything you think is private.

Configuration UI

Configuration > Integrations > Sonoff > Configure

Mode

In auto mode component using both local and cloud connections to your devcies. If device could be reached via LAN - the local connection will be used. Otherwise the cloud connection will be used. This mode is recommended for most general user.

local mode or cloud mode will use only this type of connection.

Sometimes it can be difficult to get a local connection to work. You need a local network with working Multicast (mDNS/zeroconf) traffic between the Hass and your devices. Read about common problems.

Each time the integration starts, a list of user devices is loaded from cloud and saved locally (/config/.storage/sonoff/).

auto mode and local mode can work without Internet connection. If the integration fails to connect to the cloud - the component will use the previously saved list of devices and continue to work only in local mode. auto mode will continue trying to connect to the cloud.

local mode can't work without ewelink credentials because it needs devices encryption keys.

Devices in DIY mode can be used without ewelink credentials because their protocol unencrypted. But the average user does not need to use devices in this mode.

Debug page

A link to the debug page can be found on the System Health page. Debug page shows only Integration logs and removes all private data. You can filter log and enable auto refresh (in seconds).

http://192.168.1.123:8123/api/sonoff/c8503fee-88fb-4a18-84d9-abb782bf0aa7?q=1000xxxxxx&r=2

Homes

By default component loads cloud devices only for current active Home in ewelink application. If there is only one Home in the account, it shouldn't be a problem. Otherwise you can select one or multiple Homes to load devices from.

Configuration YAML

These settings are made via YAML.

Important. DeviceID is always 10 symbols string from entity_id or eWeLink app.

Custom device_class

You can convert all switches into light by default:

sonoff:
  default_class: light  # (optional), default switch

You can convert specific switches into light, fan or binary_sensor:

sonoff:
  devices:
    1000xxxxxx:
      device_class: light
      name: Sonoff Basic
    1000yyyyyy:
      device_class: fan
      name: Sonoff Mini

You can convert multi-channel devices (e.g. Sonoff T1 2C):

sonoff:
  devices:
    1000xxxxxx:
      device_class: [light, fan]
      name: Sonoff T1 2C
    1000yyyyyy:
      device_class: [switch, light]
      name: MiniTiger 2CH

You can convert multi-channel device (e.g. Sonoff T1 3C) into single light with brightness control:

sonoff:
  devices:
    1000xxxxxx:
      device_class:
        - light: [1, 2, 3]
      name: Sonoff T1 3C

You can control multiple light zones with single multi-channel device (e.g. Sonoff 4CH):

sonoff:
  devices:
    1000xxxxxx:
      device_class:
        - switch: 1  # entity 1 (channel 1)
        - light: [2, 3]  # entity 2 (channels 2 and 3)
        - fan: 4  # entity 3 (channel 4)
      name: Sonoff 4CH

You can change device_class for Binary Sensor:

sonoff:
  devices:
    1000xxxxxx:
      device_class: window

You can change device_class for Cover:

sonoff:
  devices:
    1000xxxxxx:
      device_class: shutter

Custom devices

sonoff:
  devices:
    1000xxxxxx:
      name: Device name from YAML  # optional rewrite device name
      host: 192.168.1.123  # optional force device IP-address
      devicekey: xxx  # optional encription key (downloaded automatically from the cloud)

Custom sensors

If you want some additional device attributes as sensors:

sonoff:
  sensors: [staMac, bssid, host]

Force update

You can request actual device state and all its sensors manually at any time using homeassistant.update_entity service. Use it with any device entity except sensors. Use it with only one entity from each device.

As example, you can create an automation for forced temperature updates for Sonoff TH:

trigger:
  - platform: time_pattern
    minutes: '3'
action:
  - service: homeassistant.update_entity
    target:
      entity_id: switch.sonoff_1000xxxxxx

Preventing DB size growth

Pow devices may send a lot of data every second. You can reduce the amount of processed data.

For multi-channel devices use power_1, current_2, etc.

sonoff:
  devices:
    1000xxxxxx:
      reporting:
        power: [30, 3600, 1]  # min seconds, max seconds, min delta value
        current: [5, 3600, 0.1]
        voltage: [60, 3600, 5]
  • if new value came before min seconds - it will be "delayed"
  • if new value came between min and max seconds
    • if delta lower than delta value - it will be "delayed"
    • otherwise - it will be used
  • if new value came after max seconds - it will be used
  • any used value will erase "delayed" value
  • new "delayed" value will overwrite old one
  • "delayed" value will be checked for the above conditions every 30 seconds

Sonoff Pow

Support power, current and voltage sensors via LAN and Cloud connections. Also support energy (consumption) sensor only with Cloud connection.

By default energy data loads from cloud every hour. You can change interval via YAML and add history data to sensor attributes (max size - 30 days, disable - 0). For multi-channel devices use energy_1, energy_2.

sonoff:
  devices:
    1000xxxxxx:
      reporting:
        energy: [3600, 10]  # update interval (seconds), history size (days)

template:
  - sensor:
      - name: "10 days consumpion"
        unit_of_measurement: "kWh"
        state: "{{ (state_attr('sensor.sonoff_1000xxxxxx_energy', 'history') or [])|sum }}"

You can also setup a integration sensor, that will collect energy data locally by Hass:

sensor:
  - platform: integration
    source: sensor.sonoff_1000xxxxxx_power
    name: energy_spent
    unit_prefix: k
    round: 2

Sonoff TH

Support optional Climate entity that controls Thermostat. You can control low and high temperature values and hvac modes:

  • heat - lower temp enable switch, higher temp disable switch
  • cool - lower temp disable switch, higher temp enable switch
  • dry - change control by humidity with previous low/high switch settings

In dry mode, the Thermostat controls and displays Humidity. But the units are displayed as temperature (Hass limitation).

Thermostat can be controlled only with Cloud connection. Main switch and TH sensors support LAN and Cloud connections.

Sonoff RF Bridge 433

RF Bridge support learning up to 64 signals (16 x 4 buttons).

Video HOWTO from @KPeyanski

Automatic Calls and Messages from Home Assistant, Sonoff RF Bridge and Smoke Detectors

Important. Integration v3 supports automatic creation of sensors for RF Bridge. All buttons will be created as Button entity. All alarms will be created as Binary sensor.

Both button and binary sensor has last_triggered attribute with the time of the last signal received. You can use it in automations.

Binary sensor will stay in on state during 120 seconds by default. Each new signal will reset the timer. Binary sensor support restore state between Hass restarts.

If you has door sensor with two states (for open and for closed state) like this one, you can config payload_off as in the example below. Also disable the timeout if you do not need it in this case (with timeout: 0 option).

You can use any device_class that is supported in Binary Sensor. With device_class: button you can convert sensor to button.

PIR Sensor

sonoff:
  rfbridge:
    PIR Sensor 1:  # button/alarm name in eWeLink application
      device_class: motion
      timeout: 60  # optional (default 120), timeout in seconds for auto turn off

Single State Sensor

sonoff:
  rfbridge:
    Door Sensor 1:  # button/alarm name in eWeLink application
      name: Door Sensor  # optional, you can change sensor name
      device_class: door  # e.g. door, window
      timeout: 5

Dual State Sensor

sonoff:
  rfbridge:
    Sensor1:  # button/alarm name in eWeLink application (open signal)
      name: Window Sensor  # optional, you can change sensor name
      device_class: window  # e.g. door, window
      timeout: 0  # disable auto close timeout
      payload_off: Sensor2  # button/alarm name in eWeLink application (close signal)

You can read more about using this bridge in wiki.

Sonoff GK-200MP2-B Camera

Currently only PTZ commands are supported. Camera entity is not created now.

You can send left, right, up, down commands with sonoff.send_command service:

script:
  left:
    sequence:
      - service: sonoff.send_command
        data:
          device: '012345'  # use quotes, this is important
          cmd: left

device - this is the number from the camera ID EWLK-012345-XXXXX, exactly 6 digits (leading zeros - it is important).

Common problems in only LAN mode

auto mode and cloud mode users don't have these problems.

Devices are not displayed

  • not all devices supports local protocol
  • two routers
  • docker with port forwarding
  • virtual machine with port forwarding
    • you must use bridge virtual network mode (not NAT mode)
  • Oracle VM VirtualBox
  • linux firewall
  • linux network driver
  • incorrect network interface selected in Configuration > Settings > Global > Network

The devices publish their data through Multicast DNS (mDNS/zeroconf), read more.

Devices unavailable after reboot

All devices unavailable after each Home Assistant restart. Devices are automatically detected in the local network after each restart. Sometimes devices appear quickly. Sometimes after a few minutes. If this does not happen, there are some problems with the multicast / router.

Raw commands

The component adds the service sonoff.send_command to send low-level commands.

Example service params to single switch:

device: 1000xxxxxx
switch: 'on'

Example service params to multi-channel switch:

device: 1000xxxxxx
switches: [{outlet: 0, switch: 'off'}]

Example service params to dimmer:

device: 1000123456
cmd: dimmable
switch: 'on'
brightness: 50
mode: 0

Getting devicekey manually

The average user does not need to get the device key manually. The component does everything automatically, using the ewelink account.

  1. Put the device in setup mode
  2. Connect to the Wi-Fi network ITEAD-10000, password 12345678
  3. Open in browser http://10.10.7.1/device
  4. Copy deviceid and apikey (this is devicekey)
  5. Connect to your Wi-Fi network and setup Sonoff via the eWeLink app
