Heating and cooling

The objects of a heater or a cooler (a radiator, a split, a heated floor) glow orange while it heats, light blue while it cools, teal while it dries. A tap opens the entity, to change the target.

• A thermostat (climate.*) says what it does in hvac_action; without it, its mode and its current and target temperatures tell it.
• Any other entity heats while it is on: the switch of a boiler, the plug of an electric radiator. mode: cool makes it a cooler.

- entity: climate.living_room_valve # or switch.boiler
  type3d: climate
  object_id: radiator_living

Option	Default
heat_color	#ff6a00	The glow while it heats.
cool_color	#38bdf8	The glow while it cools.
glow	0.8	How bright the glow is.
mode	heat	For a switch or a plug: cool when on means cooling.

A room can also show its thermostat: with climate in the room, the temperature map writes the target next to the temperature, 20.5 °C → 22 °C, on orange while it heats and on blue while it cools.
