Yeah, the automated/remote controlled heating system world, and also the ringbell world is basically a giant scam, since they are updates on world that also scammed you in the past. I cried when I shelled out so much money for my Tado device, but even a dumb bTicino device costed in the hundred of euros realm, and it's just a sensor + a small LCD display and a designed-in-hell menu system to program it. And the same happens in Ip-based ringbells. A Doorbird will cost you hundreds of euros for what is basically a webcam plus some nice metal casing and a shitty software, but it competes with analog systems with optic cables etc that cost basically the same or more.
