Change Switch Icon if On?

Configuration
1

I have two workshop hanging lights controlled by MQTT wifi smart plugs. These are grouped together currently.

group:
  workshop_lights:
    name:  Workshop Lights
    entities:
      - switch.workshop_east_hanging_lights
      - switch.workshop_west_hanging_light
    icon: mdi:ceiling-light

On my dashboard, I have these showing where I can switch them on and off, but I’d also like the icon to change when turned on to be yellow like the “lights” that are on. Is there a way to do this?

Use the state_color option in your Lovelace entities card:

entities:
  - entity: group.workshop_lights
    state_color: true
  - etc...

Ok, when I do:

entities:
  - entity: light.living_room_lights
  - entity: light.front_patio_lights
  - entity: switch.jasco_products_12722_on_off_relay_switch_switch
  - entity: light.jason_office_lights
  - entity: group.workshop_lights
    state_color: true
  - entity: switch.jasco_products_12720_outdoor_smart_switch_switch
title: Lights / Power
type: entities

I get:

Expected a value of type {entity,name,icon} | entity-id for entities.4.state_color but received true.

Ok, along that path I changed it to:

entities:
  - entity: light.living_room_lights
  - entity: light.front_patio_lights
  - entity: switch.jasco_products_12722_on_off_relay_switch_switch
  - entity: light.jason_office_lights
  - entity: group.workshop_lights
  - entity: switch.jasco_products_12720_outdoor_smart_switch_switch
title: Lights / Power
state_color: true
type: entities

This still gets an error: Expected a value of type undefined for state_color but received true.

The weird thing is that some devices that didn’t change color before now do, but this one doesn’t. :face_with_raised_eyebrow:

I suspect this is a bug.

How about a light group instead, might behave differently?

You’d need to make the switches lights as well, presumably.

7

I don’t think I can make these into lights as they are smart plugs. I believe they were discovered as switches automatically.

8

That does look like a bug.

You can make light entities based on switches:

Are you using the GUI? If yes, this is a warning (yellow = warning) not an error. You’ll notice that your switches will now be yellow when on.

They are not.

Yours is using a switch entity directly. Mine was using a group. There appears to be a bug with groups not updating the state_color.

BTW, I made light entities out of the switches, grouped them as a light group, and it works great now.

Groups have more than on/off states, they have never worked with state_color. Groups can have home, not_home, sensor values, zone names, on, off, as states.
