Trying to use Powercalc for HVAC power calculation

Have tried several of forum suggestion but can’t get it to work.

I want to calculate my floor heating and som room heating that I don’t have real power metering for yet.

There seems to be both in powerful documentation under cookbook a starting point and also in some forum post addressing it in some different ways.

Creating it in Powercalc GUI does create a sensor but not values.

Testing starting to add it to configuration.yaml
Creates sensor but mu domain grouping stops working.

configuration.yaml:

PowerCalc config

powercalc:
enable_autodiscovery: true
create_domain_groups:
- light
- media_player
sensors:
- entity_id: climate.smart_thermostat_2208024842426960120148e1e99cdad7
name: FloorHeat Dusch
fixed:
attribute: hvac_action
states_power:
idle: 1
heating: 100

Developer tools, State:

PS can’t find a way to delete the sensor created in Powercalc gui that are not working .
