Automatic (open and close after time) different windows - Tado and Velux

Configuration
1

Hello,

I’m still pretty new to Home Assistant.

I want to solve the following:

In one room there are 3 skylights (electric) and 2 thermostats for the radiators.

Now I would like to achieve the following:

When a window is open, the thermostats (valves) on the radiator should close. Regardless of which window is open.
After closing, the heating should switch on again automatically.

Tado and Velux are in use.
How do I implement this when it comes to checking the windows so that it can be determined which window is currently open.

It would also be great if you could configure the window or windows to close automatically after a certain time (example: 30 minutes).

Use the search function or take a look at this Blueprint

Thanks for the tip. i´ll try it…

Unfortunately, the blueprint didn’t work as well as I wanted.
Now I have solved it like this for myself:

I have 3 roof windows that can be opened independently and 2 radiators with thermostats (and a higher-level thermostat)

It is now checked whether windows are open, then the heating is turned off. When closing, check whether everything is closed, then turn on the heating.

And that’s for checking whether all windows are closed, then setting the heating to AUTO.
Triggered when any window is closed.

Glad you got something that works.
You can create a helper that combines the states of the window such that it’s true if one of more windows are open and false if all are closed. This will simply your automation.
Another thing you should consider is to use scenes for the heater/ac. When a window is opened you create a scene with your heater/ac device which you then restore once the windows are closed again.
In your implementation I don’t think the thermostat will return to the same settings (temperature) when windows are closed
Finally - you should also consider the scenario where a window is open and someone turns on the heater/ac. In that scenario your heater will continue to heat.

Thank you for the tips from the helpers.
Unfortunately, I’m not that good with Home Assistant yet, but I’ll get there.

With my automation, the heating then returns to its original state, i.e. back to the valid time program with the setpoints.

There are only two of us who don’t control the thermostats by hand.
