STATUS: [UN-MAINTAINED]. Due to personal reasons I am not using this integration anymore. I do not have the time to actively maintain it. Feel free to fork/take-over. I had made in try to get it merged into home assistant: home-assistant/core#77737 but never got around to finish it.
Home Assistant Climate Group
Groups multiple climate devices to a single entity. Useful if you have for instance multiple radiator thermostats in a room and want to control them all together. Inspired/copied from light_group component (https://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/group/light.py)
