Tasmota

While automatic discovery is the recommended method, an advantage of manually configuring device is the user maintains control of all aspects of the device configuration and usage.

Hass configuration not exposed in the UI is done by editing the file configuration.yaml which is found in folder .homeassistant after installation and first start of Hass.

Note: After every change to the configuration file you'll need to restart Hass to make it aware of the changes. This can be done either:

Through the UI: Configuration -> General -> Server Management -> Restart
From command line: On a Debian Linux based system, use the command sudo systemctl restart home-assistant.

In the examples shown the following Tasmota parameters are set:

MQTT_STATUS_OFF in user_config.h = OFF
MQTT_STATUS_ON in user_config.h = ON
SUB_PREFIX in user_config.h = cmnd
PUB_PREFIX in user_config.h = stat
PUB_PREFIX2 in user_config.h = tele
Mqtt = 1
MqttHost = domus1
MqttPort = 1883
Topic = sonoff
PowerRetain = 0
TelePeriod = 300

Note: If the power state needs to be persistent across Tasmota reboots set the PowerRetain to 1.

If you are using a localized version (eg. de-DE) be sure to check the correct spelling and cases for the defines:

'D_ONLINE' for 'payload_available'
'D_OFFLINE' for 'payload_not_available'
'D_ON' for 'payload_on'
'D_OFF' for 'payload_off'

Hass configuration - MQTT broker

As Tasmota is MQTT based you will need to configure Home Assistant to connect to an MQTT broker.

Home Assistant comes with an embedded MQTT broker which is easy to set up but you may want to opt for a separate MQTT broker instead for better stability. A popular choice for this is the open-source Eclipse Mosquitto.

Configure an external broker

To connect Hass to an external MQTT server, use Hass web UI:\

Configuration -> Integrations -> Set up a new Integration -> MQTT\

Note: Make sure to tick the "Enable discovery" option to enable MQTT device discovery.

Configure the embedded broker

# Example configuration.yaml entry
mqtt:
  password: hello

Default username for the embedded broker is homeassistant while port defaults to 1883.

Tips

Tip: Sync power state

If the MQTT broker or Hass is restarted, or there is a WiFi outage, Tasmota device state may not be synced with Home Assistant.

Use this automation to get all your devices in sync, including power state, after Home Assistant is (re)started.

# Example automations.yaml entry
- alias: "Power state on HA start-up"
  trigger:
    platform: homeassistant
    event: start
  action:
    - service: mqtt.publish
      data:
        topic: "cmnd/tasmotas/state"
        payload: ""
    - service: mqtt.publish
      data:
        topic: cmnd/tasmotas/POWER
    - service: mqtt.publish
      data:
        topic: cmnd/tasmotas/POWER2
    - service: mqtt.publish
      data:
        topic: cmnd/tasmotas/POWER3

This automation posts to the default "sonoffs" group topic. Each device will send back their status message which contains relay power and light status.

Tip: View the firmware version number of a Tasmota device

Add a sensor like below in your sensor section for each Tasmota device in one card in an order that makes sense for you. Change the state_topic and availability_topic to the unique topic of each device.

# Example configuration.yaml entry
sensor:
  - platform: mqtt
    name: "S20_Rock"
    state_topic: "stat/S20Beta/STATUS2"
    value_template: "{{value_json['StatusFWR'].Version }}"
    qos: 0
    availability_topic: "tele/S20Beta/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"

Automation to have each device to push out the firmware version on Home Assistant reboot. Tip: The user can manually trigger this automation without a reboot during upgrades of devices.

# Example automations.yaml entry
- alias: "Sonoff state on HA start-up"
  trigger:
    platform: homeassistant
    event: start
  action:
    - service: mqtt.publish
      data:
        topic: "cmnd/tasmotas/STATUS"
        payload: "2"

Tip: Get the IP address of a newly flashed Sonoff (ESP8266)

Here is some code that will display the IP address of you newly flashed ESP8266 if you have to change PROJECT name in user_config.h you must also change the script topic has to match it.

The script:

# Example scripts.yaml entry
 get_sonoff_ip:	
  alias: Get Sonoff New IP (sonoff)	
  sequence:	
  - data:	
      topic: cmnd/tasmota/ipaddress	
    service: mqtt.publish

topic: cmnd/the PROJECT NAME/ipaddress

The sensor:

# Example configuration.yaml entry
sensor:
  - platform: mqtt
    name: "SonOff IP"
    state_topic: 'stat/tasmota/RESULT'
    value_template: "{{ value_json.IPAddress1.split(' ')[1].replace('(','').replace(')','') }}"

Put it into a group

# Example groups.yaml entry
  sonoff:
    name: "Sonoff Tasmota"
    control: hidden
    entities:
      - script.get_sonoff_ip
      - sensor.sonoff_ip

restart HA plug in your newly flashed ESP8266 Click EXECUTE (in the new group) and It will display the IP address in the "Sonoff IP" sensor, don't forget to change the topic name in "Configure MQTT" in the Configuration Menu.

Tip: WiFI RSSI Signal Strength

Display the WiFi signal strength published from each telemetry message (default time is every 300 seconds). Change the two topics below to your Tasmota device name. It may not immediately show on your Home Assistant panel until the next telemetry message is published.

# Example configuration.yaml entry
sensor:
  - platform: mqtt
    state_topic: "tele/SNF-Washer/STATE"
    name: "Washer Signal"
    unit_of_measurement: "%"
    value_template: "{{value_json['Wifi'].RSSI }}"
    availability_topic: "tele/SNF-Washer/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"

Configure Switches

Use the switch.mqtt component.

Use POWER1, POWER2, etc when you are using a device with more than one relay (if SetOption26 is on you must also use POWER1 even if only one relay exists)

# Example configuration.yaml entry
switch:
  - platform: mqtt
    name: "Sonoff power"
    state_topic: "stat/tasmota/RESULT"
    value_template: "{{ value_json.POWER }}"
    command_topic: "cmnd/tasmota/POWER"
    availability_topic: "tele/tasmota/LWT"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    payload_available: "Online"
    payload_not_available: "Offline"
    retain: false

If you are using your Sonoff to control a light, you may want to use the Use the light.mqtt component. component. Simply replace switch with light in the above configuration. All other settings remain the same.

Configure Sensors

Use the sensor.mqtt component.

DHT22 sensor

Periodical updates

A DHT22 Temperature and Humidity sensor connected to a Sonoff TH10 will send at TelePeriod intervals the following information to the MQTT broker:

tele/tasmota/SENSOR = {"Time":"2017-02-12T16:11:12", "DHT22":{"Temperature":23.9, "Humidity":34.1}}

To make the information visible in HA add the following lines to the configuration file.

# Example configuration.yaml entry
sensor:
  - platform: mqtt
    name: "Tele Temperature"
    state_topic: "tele/tasmota/SENSOR"
    value_template: "{{ value_json['DHT22'].Temperature }}"
    unit_of_measurement: "°C"
    availability_topic: "tele/tasmota/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"
  - platform: mqtt
    name: "Tele Humidity"
    state_topic: "tele/tasmota/SENSOR"
    value_template: "{{ value_json['DHT22'].Humidity }}"
    unit_of_measurement: "%"
    availability_topic: "tele/tasmota/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"

This periodic interval can be changed using the TelePeriod command (see the wiki for the MQTT commands).

Manual updates

Another means of sensor information retrieval from Tasmota is using the status command Status 10 or cmnd/tasmota/status 10. This would result in a message like:

stat/tasmota/STATUS10 {"StatusSNS":{"Time":"2017-02-11T18:06:05", "DHT22":{"Temperature":"21.8", "Humidity":"48.0"}}}

The HA configuration would then look like this:

# Example configuration.yaml entry
sensor:
  - platform: mqtt
    name: "Stat Temperature"
    state_topic: "stat/tasmota/STATUS10"
    value_template: "{{ value_json.StatusSNS.DHT22.Temperature }}"
    unit_of_measurement: "°C"
  - platform: mqtt
    name: "Stat Humidity"
    state_topic: "stat/tasmota/STATUS10"
    value_template: "{{ value_json.StatusSNS.DHT22.Humidity }}"
    unit_of_measurement: "%"

The Tasmota command could be initiated by a mosquitto mqtt pub command on mosquitto_pub -h localhost -t 'cmnd/tasmota/status' -m '10'

HTU and BMP I2C sensors

HTU21 and BMP280 sensors connected to sonoff2 send messages like:

tele/sonoff2/SENSOR = {"Time":"2017-02-12T16:16:43", "HTU21":{"Temperature":24.0, "Humidity":34.0}, "BMP280":{"Temperature":24.9, "Pressure":1032.5}}

Where the Pressure information would be made available to HA with

# Example configuration.yaml entry
sensor:
  - platform: mqtt
    name: "Tele Pressure"
    state_topic: "tele/sonoff2/SENSOR"
    value_template: "{{ value_json.BMP280.Pressure }}"
    unit_of_measurement: "hPa"

Sonoff Pow Energy sensors

Periodical updates

A Sonoff Pow device called pow1 will periodically send the following message:

tele/pow1/SENSOR = {"Time":"2018-02-14T21:51:31","ENERGY":{"Total":0.984,"Yesterday":0.000,"Today":0.984,"Period":12,"Power":145,"Factor":0.90,"Voltage":220,"Current":0.731}}

The HA configuration for Energy, Power, Voltage and Current would be:

# Example configuration.yaml entry
sensor:
  - platform: mqtt
    name: "Energy"
    state_topic: "tele/pow1/SENSOR"
    value_template: '{{ value_json["ENERGY"]["Today"] }}'
    unit_of_measurement: "kWh"
  - platform: mqtt
    name: "Power"
    state_topic: "tele/pow1/SENSOR"
    value_template: '{{ value_json["ENERGY"]["Power"] }}'
    unit_of_measurement: "W"
  - platform: mqtt
    name: "Voltage"
    state_topic: "tele/pow1/SENSOR"
    value_template: '{{ value_json["ENERGY"]["Voltage"] }}'
    unit_of_measurement: "V"
  - platform: mqtt
    name: "Current"
    state_topic: "tele/pow1/SENSOR"
    value_template: '{{ value_json["ENERGY"]["Current"] }}'
    unit_of_measurement: "A"

Manual updates

The manual message retrieved with command Status 8 or cmnd/pow1/status 8 will show:

stat/pow1/STATUS8 = {"StatusPWR":{"Yesterday":0.002, "Today":0.002, "Power":4, "Factor":0.37, "Voltage":227, "Current":0.056}}

The HA configuration for Power Factor would then be:

# Example configuration.yaml entry
sensor:
  - platform: mqtt
    name: "Power Factor"
    state_topic: "stat/pow1/STATUS8"
    value_template: "{{ value_json.StatusPWR.Factor }}"

Configure Lights

Use the light.mqtt component.
