I see the /BatteryVoltage in Dbus-spy and MQTT. I have a temperature sensor that I added via a "dummy service" and I update the sensor values via modbusTCP . I am wanting to update the sensors battery voltage with modbustcp as well.
These are the Temperature sensor registers I see on my CCGX running v2.80 ~33
Thank you,

We’ll check, thank you. And see: https://github.com/victronenergy/venus/issues/889#issuecomment-1011790859
Can I ask how do you write the temperature values by modbus tcp interface? I am getting an error suggesting the register is not writable. The register spreadsheet also suggests the temperature value is not writable.
By default most of the modbustcp registers are set to read only. You will need to change the registers that you want to write to by updating the paths to writable in the /opt/victronenergy/dbus-modbustcp/attributes.csv file and reboot .
For example with a temperature sensor, change the R (read only) to W ( writable)
com.victronenergy.temperature,/Temperature,d,Degrees celsius,3304,int16,100,R
com.victronenergy.temperature,/Temperature,d,Degrees celsius,3304,int16,100,W
Thanks, I'll look into that.
