How to handle smart switches with powermeter, that do not provide an energy sensor.

[sgiffhorn]

I have some Tuya Wifi smart switches which provide "power", "voltage" and "current". However they do not provide "energy".

Until now I just had created a PC instance via "Energy from real power sensor" to get the energy sensor. Now I have measured the standby off/on values of the smart switch and created a custom model for the switch to also get the Device Power/Energy.

However now I have to create 2 instances of PC for this device to get both the energy from the load of the switch as well as the power/energy from the switch itself.

Is there any way to combine both?

You could create a group to combine them in one sensor.

Besides that there is no way to combine them

Ah sorry, my description was maybe a bit misleading. I didn't mean to combine the device power/energy with the load power/energy, but to have (to create) only one instance of PC for that device.

So basically what I would need in this case is a hybrid of a custom model that provides the settings to create the device standby power/energy sensors as well as the possibility to specify (in the UI dialog when adding the device) the load power source to create the load energy sensor from.
