Maybe I’m missing something, but it seems I can only use hvac_onoff_register to point to a Holding Register (or I suppose what ever is set on input_type)
But on LG Airco/Heatpump/… device this is always done using a coil.
It would be nice to have a hvac_onoff_coil option.
Or any other solution that would allow me to sove this issue without having to hack in a 3rd party solution supporting template based climate entities.
