So i’ve been thinking about this for quite some time, since my Airco’s (Daikin) connect to homey and my infloor heating/radiator heating is connected to Nest (which now also works in Homey, I wanted to see if there is a nice way to create a flow or something to add the airco as secondary heating. In each room in the house I also have Netatmo Home Coach devices that can read temperature and more per room.
The reason; to use less gas and the main heating not turning on for every time the temperature goes below 20 degrees and be able to get some extra heat only in the rooms necessary.
So for example;
During the day; Leave the main thermostat on 18 degrees celsius,
During the day (like between 8 and 22hrs at night), when the temperature is below 20, start the airco in that room to heat from the 18 upto 20 (so to cover the difference).
Stop airco heating when it’s above 21/22 degrees per room,
Stop airco heating when it’s after 22hrs at night
What do you all think about this? And how would you do it with flows? Would love to know more thoughts/ideas.
Your temperature changes every once in a while, for example: you are leaving your door open the temperature drops for like -0.1 that is enough to trigger the flows.
I used my tado thermostat for it. But you can use other devices that can measure temperature.
You can trigger it in many ways, for me this was the best setup. You can also use other flows to activate this one.
Heating is 18c ( set temp for the central heating ) + 2.8 = 20.8c ( so if the temperature is < 20.8 it starts the AC )
18c + 3.5 = 21.5 > turns ac off
The set temperature is logic is from the tado thermostat that is set to eg. 18c
But you can use any device that measures temperature. the first value ( set temp ) needs to come from your central heating, in my case tado. but you should be able to use any thermostat that works with your central heating and homey.
