Battery voltage for AIO

TimClement commented 8 months ago

The AIO does not appear to have a battery details topic, but does provide the battery voltage in the raw JSON (and it also shows in the GE app as a battery statistic). Would it be possible to feed this to HA as a sensor if raw input is enabled? It might be of interest to people seeing the "sudden drop in SOC on discharge" issue.

Battery details for AIO are a WIP. Its a completely different data structure, so I need to modify the underlying (un-maintained) library. I'm planning on getting this working before 2.5.0

Came here to ask about this, after discussing with Paul on the groups that the registers are there it's great to hear that you're looking into this @britkat1980.

You can add manually to HA, via MQTT, in the meantime

mqtt:
  sensor:
    - name: AIO#1 Battery Voltage
        unique_id: 6b27bc8d-0b08-4131-85d1-d2304c79226d
        force_update: true
        icon: mdi:flash-triangle-outline
        device_class: voltage
        state_class: measurement
        qos: 0
        unit_of_measurement: "V"
        state_topic: "aio1/CH<serial>/raw/invertor/v_battery"
    - name: AIO#1 Battery Current
        unique_id: 10c410c5-1bd4-4e88-8577-666b4e575818
        force_update: true
        icon: mdi:current-dc
        device_class: current
        state_class: measurement
        qos: 0
        unit_of_measurement: "A"
        state_topic: "aio1/CH<serial>/raw/invertor/i_battery"

I've done this and it's working fine for about a month now...Just check the topic string suits your specific setup...

@pbyrne-ms Thanks - I now have this up and running (with a little help from MQTT Explorer to get the first part of the topic name right).
