HVAC Group

Create a custom thermostat to control multiple other climate components. Useful for controlling an AC unit and a heating unit in a single room.

As it is, the integration is way behind the current HA version and is unlikely to work. It is advisable that you don't use it for now.

This integration will set up the following platforms.

Platform	Description
`climate`	The replacement thermostat which can control other nested thermostats.

The resulting thermostat will control all child members (heaters and coolers), but controlling a child won't propagate the change back to the group. The hvac_action of the group is not related directly to the hvac_action of the child members.

Installation

HACS

If you're using HACS, go to "HACS" > "Integrations" and search for the HVAC Group integration, then download it

Name your new HVAC group. Something like Bedroom climate
Select one or more heating entities (e.g. the radiators and the electric heater in the bedroom)
Select one or more cooling entities (e.g. the air conditioning in the bedroom)
For both heaters and coolers, if you check Toggle heaters/coolers on or off [...], they will physically be turned off if the desired temperature is reached
Select a climate entity or a temperature sensor which holds the current temperature (Temperature sensor)
