I’ve added a few custom icons to some booleans I’ve made. I use them for turning some lights on and disable my motion detectors.
But the problem is, that the icon doesn’t update like normal “light” does when switched on. The icon remains the same:
The documentation does not mention the icon will change according to input_boolean’s state.
I believe the ability to automatically change the icon according to the state is only supported by lights, switches, template_sensors, and binary_sensors.
