free/open technology for home heating systems

[Daniel Pocock]

There are government grants in Ireland for heating controls, I put more
details on my blog[1].

Is anybody aware of technology for this purpose that is running free
software and interfaces with free/open standards?

Can this be achieved using a custom solution with Raspberry Pi or
similar devices running free software?

Regards,

Daniel
