I am a complete and total beginner to not only HestiaPi, but also Rasberry Pi so I have a few questions regarding this product. I am looking to somehow integrate an occupancy sensor into an open-source thermostat like the Hestia Pi Touch to control my HVAC system while I am not in a room/my home. I was just wondering what would be the best way to go about this. Could I integrate a sensor with the already built HestiaPi, or would it be easier to get the DIY kit and integrate it that way? Alternatively, would the easiest route be just to build my own thermostat from scratch using a Pi? Excuse my ignorance, but much of this process is very new to me so I am just trying to get a good idea of the best route to take to achieve my goal of a fully open-source thermostat for my home.
Thanks for all you guys do on the forum!
