Battery indication for MQTT sensors (self.homeassistant)

submitted 9 months ago by peregus to c/homeassistant

4 comments fedilink hide all child comments

I have some sensors like this one:


  - name: "Sala"
    unique_id: "temp_sala"
    state_topic: "zigbee2mqtt/temp_sala"
    value_template: "{{ value_json.temperature }}"
    unit_of_measurement: "°C"

Those sensors publish the battery status too, how can I add it? Thanks!

One way is to make a new "entity", that's not actually linked to your previous temperature sensor. I'm not familiar with how to tie them together in a "device" like how ZigBee2mqtt auto discovery does.

So just add a new "sensor"/"entity"

  - name: "Sala_battery"
    unique_id: "temp_sala_battery"
    state_topic: "zigbee2mqtt/temp_sala"
    value_template: "{{ value_json.battery }}"
    unit_of_measurement: "%"

Use MQTT Explorer to listen to your ZigBee2mqtt broker topic "zigbee2mqtt/temp_sala" to get the exact field name (battery, battery_state or some such)
