(I wasn't sure where to post this. If a moderator wants to re-categorize this, thats fine.)
Has anyone used the temperature sensors and relays to completely control a home heating system? I'm planning a hydronic installation (boiler/radiators) in my house this summer, and I hate the idea of a closed consumer system to control it all. Especially with a house full of Linux systems already up and running for prototyping.
I will also be adding solar hot water to it in a year or two, and like the expandability these devices would afford.
How does the long term lifespan of these devices look? Any reason they wouldn't last a minimum of 10+ years of continuous use?
