Is it possible to implement the OpenTherm protocol in LinuxMCE?

QuoteWhat is OpenTherm?

OpenTherm is the name of a non-manufacturer-dependent system of communication between modulating heating appliances (central heating appliances and air heaters) and room thermostats. The system consists of a communication protocol and an interface specification. OpenTherm is futuristic system, which combines simple installation techniques with high functionality and future expansion possibilities.

LinuxMCE has a good implementation on Zwave. What are the technical and price adventages of this standard?

Well, if linuxMCE supports OpenTherm, linuxMCE can directly communicate with central heating appliances and air heaters. Without having to buy a special thermostat with Zwave capabilities. linuxMCE then can act as a software thermostat. You don't have to buy (expensive) Zwave equipment.

That's interesting.  However, there are a very few supported systems at the moment.  It looks like the system is uses RS-232 as a communications bus.  The modular nature of LinuxMCE should make the creation of a 'device' in the software fairly straightforward.  This would be interesting to play with.  How does Opentherm handle 'zoned' climate control?  It looks like a single thermostat controls a single heater.
