Energy / add Synope thermostat

Hello, I would like to add the data of a Synope TH1124ZB-G2 thermostat in my Energy table.

I notice that the variable “device_class” = temperature. This does not comply with HA guidelines. On this page ( Frequently Asked Questions about home energy management - Home Assistant ) it says to report the situation.

However, the “state_class” variable does not exist.

The “unit_of_measurement” variable = °C

I notice that there are several variables concerning power consumption. What can I do to include the data in my Energy table?

Thank you for your valuable advice
