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)

      Zigbee2mqtt should do device auto discovery by default

      It does, but this is a remore device and I don’t wanna redirect all the homeassistant/# messages from zigbee2mqtt to my home MQTT broker.

        Then to link the entities together into a device you need to mimic the auto discovery, or you just have two split entities.

        I suppose you could create a template entity with the battery as an attribute to see it in the details view, but you still need the entities with the raw data. I’d be more inclined to create the device with auto discovery, seems like a cleaner way to go.
