Hi
I have a Victron inverter with battery storage. I am monitoring various battery parameters including % charge, voltage, current, and power in/out.
I’ve started getting warnings as follows:
Sensor with invalid unit of measurement
Warning ⸱ Reported by MQTT
This stops working in version 2025.7.0. Please address before upgrading.
Manual configured Sensor entity sensor.cerbo_gx_battery_power has a configured unit of measurement W which is not valid with configured device class battery. Make sure a valid unit of measurement is configured or remove the device class, and [reload]
Manual configured Sensor entity sensor.cerbo_gx_battery_voltage has a configured unit of measurement V which is not valid with configured device class battery . Make sure a valid unit of measurement is configured or remove the device class,
Manual configured Sensor entity sensor.cerbo_gx_battery_current has a configured unit of measurement A which is not valid with configured device class battery .
All the above parameters seem to be very much part of a battery’s monitoring requirements, but the battery definition in HA only supports % Charge as a parameter
Questions:
Am I doing anything wrong?
Have I mis-understood anything?
How do I resolve this error?
Many thanks
Tim R
