Hope this question is on topic here.
I am wondering how to automate my windows. Ultimately I want them to open / close depending on a number of data points like: CO2 Levels, Temperature, Humidity, Time of day, etc.
There are solutions for this, using zigbee, which is perfect for me, but they cost between 70-140$.
These solutions typically look something like this:
This solution, apart from being kind of expensive, has a drawback: I would have to keep my window handles on “open” for it to work.
I was wondering, if there is another way to do it?
The next easiest, but cheaper way would be to buy a motor like this one (15-20$):
Depending on the way you connect the wires, it either opens or closes (plus to plus: open, plus to minus: close), which means I would need 2 zigbee switches for each about 10$ in addition + power source.
What other solutions are there? I have seen some turorials for this online, but they require 3d printed parts.
What if I wanted to automated the window handle itself? Is there anything else worth looking into?
