How to set device class

[Safs]

Hello!

Is it possible to set "device_class"? I need device_class "gas" instead of "energy"

Thanks!

Hello, this is not yet possible. And no plans to (at least not short term).
energy sensors are riemann sum sensors (as the helpers in HA), and they are specifically for kWh, also power sensors is the base for this.
So I don't see how you want to use this anyway.
You probably should have a look into the HA template sensors

Energy sensors not apper in gas section of energy dashboard, that is my problem...

[bramstroker]

Because it's energy, not gas. These are 2 completely different things.
Powercalc was designed to do power and energy, not gas or water.
So you can't use powercalc to record gas.

Ok, thanks!

One more question, how to reset kWh counter, or how to set value, from what to start to accumulate?
