battery_temperature not working

[kkaminski7]

Hi I have "Victron Smartsolar 100/20" mppt with "Smart battery sense" connected. Everything seems to work fine so far except "battery_temperature". Is it working? Maybe I have defined it wrong in esphome, below my config for it:

    battery_temperature:
      name: "Battery Temperature"
      device_class: temperature
      state_class: measurement
      unit_of_measurement: "°C"

[syssi]

Could you enable the debug output/mode of the uart component and provide a log of your Esphome node? It should include a complete status frame of your victron device. I would like to understand which measurements are available and which aren't part of the status frame.

I have set debug according to debug-esp32-example.yaml

  debug:
    direction: BOTH
    dummy_receiver: false
    after:
      delimiter: "\n"
    sequence:
      - lambda: UARTDebug::log_string(direction, bytes);

Downloaded logs attached. logs_esphome-web-da590e_logs.txt

This is the response of your Victron device:

Do you see the temperature you are looking for here?

[syssi]

Battery temperature (key T) isn't available. It looks like your are looking for a measurement your Victron device doesn't provide (at the ve.direct ascii telegram).

I see. Thanks for your help.
