I have a 12V network of slimline thermostats connected through to a NetMonitor - which is now playing up. I have a vague plan to replace the NetMonitor with a RaspberryPi solution, which would also allow me to add features such as logging temps from the stats, demand, boiler cycling, etc. - all very exciting (not!). It's possible there are others out there who would be interested in such a solution, especially as Heatmiser, in their wisdom, have discontinued the NetMonitor and not replaced it!!!
Anyway, to progress I need to understand the thermostat protocol used on the network: when I installed the system (7 years ago) I had a document which described it - down to the packet exchanges, etc. Now I can't find it nor does it appear to be in the Heatmiser support pages. Anyone got it or can point to it?
Many thanks, Neil.
