My central heater is a simple on/off model. Nest will work offline with it but afaik you can't write target temperatures to it then.

- aequitas 7y agoTo bad, my old heater had opentherm, with the OTGW I could intercept the packets between the heater and thermostat, change values (eg: date/time), issue commands (set room temperature) and add missing functionality (outside temperature for heating curve), it was ideal in every way. But I moved and my current heater has a proprietary protocol over rs485 so its a no-go for the OTGW.
- teekert 7y agoIn the EU there are no systems without opentherm by law luckily. That does mean some systems are not available at all, so "luckily".
