free/open technology for home heating systems

[Chris]

There's the UK-based OpenTRV (Thermostatic Radiator Valve).

Their mailing list has gone quiet so I don't know current status (they have working prototypes) but the product is open source control for individual radiators (the valve) with a central hub.
"On the radiators, you screw on a thermostatic radiator valve (TRV) that can be switched on and off by radio. The OpenTRV control unit is a separate small box with just a couple of buttons and a single LED. It senses the temperature and whether anyone is in the room and if it decides or is instructed to heat up the room, signals the TRV on the radiator to open up. There is another OpenTRV unit attached to the boiler and when that unit hears the call from an OpenTRV unit to its radiator, switches on the boiler to provide hot water."

Probably not grant-approval ready but not vapourware and seem approachable from past on mailing list.
