Time for a new central heating

Yesterday we got a letter from the company that does the maintenance of our central heating. It said our current central heating was to vulnerable to failures and we were offered an upgrade to a newer central heating at a reduced price. Well, it is true that our central heating has caused us a lot of trouble through the 10 years that we live here. So i understand the reason why they want us to upgrade to a newer model from a different brand. But i’ve got my own wishes…
Our new central heating should be controlled by means of the Opentherm protocol for instance, so that i can ‘tap’ the communication between central heating and the thermostat and incorporate the data that i can get out of that, into my Domotica System. And i’ve made my choice: our new central heating will be a Remeha Avanta, controlled by a Remeha Celsia 20, including a so-called gateway for attaching a RS-232 cable to it and tap the communication.

    Have you found any info about the PC interface? The cable seems very expensive according to this forum – http://www.domoticaforum.eu/topic.asp?whichpage=1&TOPIC_ID=1453&#9451

    I’d be interested in finding out a bit more about this interface so I’ll keep an eye on your posts here in case you do.
