I’m loving this card! Thanks for creating and maintaining it.
For now I’m trying to do the following:
I have one entity which is the thermostat. Unfortunately the thermostat only tells me if it’s in heating mode, but the actual valve for activating the heating is another entity. I have solved it so that I will be able to see the state of that other entity between the sensors.
However I would love to see if it’s possible to use the main icon in the header to show this.
So the question is: how can I control the header icon (Show or type, or even color) based on the state of another entity.
entity: climate.woonkamer_wk_thermostaat_375
type: custom:simple-thermostat
header:
name: Woonkamer
step_size: '0.5'
sensors:
- entity: sensor.woonkamer_wk_kamertemperatuur_377
icon: mdi:thermometer
- entity: sensor.woonkamer_wk_kamervochtigheid_378
icon: mdi:water-percent
- entity: switch.woonkamer_convectorputklep_277
icon: mdi:power
- entity: climate.woonkamer_wk_thermostaat_375
icon: mdi:battery-40
attribute: battery_level
hide:
temperature: true
state: true
control: false
icon:
- entity: switch.woonkamer_convectorputklep_277
'on': mdi:power-on
'off': mdi:power-off
As you can see I tried to do something below with icon and then mentioning the device which I would like to control the icon. This however won’t work.
