Winter is coming, so it's a good time to take care of the heating in our homes. In this post, I will show how I built a complex heating system for my home using Home Assistant. I also have a secret agenda 🙈 It's to share my thought process when approaching

    I like this, but I don’t like that rooms are cold unless I hang out in them. I live in an old stone house and I’d rather have a room schedule than a room presence sensor.

    I’ve done something similar. I use the excellent scheduler from Niels Faber. I have room radiator TRVs. I have a helper entity that counts the number of radiators that have an open valve, and an automation that triggers when this changes to/from zero. This automation adjusts the central nest thermostat, converting it to more or less a posh switch.

    My radiator valves use Better Thermostat and external temperature sensors, and the whole thing keeps my house warm in every room. I need to write a GH blog post about it, but happy to answer questions/share bits of config

    Why not wasting 10 seconds to write something about the linked article?

      I’ll write a quick gist for anyone coming along:

      One gas boiler in the house, each room has a smart TRV.
      PIR sensor to set room presence, each window has an opening mag sensor. HASS has a general presence sensor set.

      Each room’s temperature is targeted based on presence and window status:
      For each room, if person is home at all, and has been in the room for 5 mins, and the window is closed, TRV to 19, boiler on if <19.
      If the room presence is negative and the window is closed, drop TRV target to 16.
      If the window is open, drop the TRV target to 7.

      There is a little more detail that that in the article, but that’s the basics.
