@tom_l that is quiet cool. thanks for this. definitely gonna keep that in mind. but not quite what i’m looking for. i want to change the battery icon of said sensor to a house icon (hence mdi:home).
@VDRainer thanks for the pointer. but i can’t figure out where to put icon_template in the above sensor. i’m quite new to HA and have been using it for only two month or so.
I prefer to keep them with the entity config if possible. That way if I delete the entity six months later I don’t forget to delete the customization and end up with orphan icons in customize (that do not generate errors).
