Re: Re: Heatmiser Central Heating Thermostat

Have you had a go at reverse engineering the protocol for the stats?  I
would imagine its based on a standard protocol such as RS232, RS 485,
LIN etc and so wouldn't be too hard to understand?  If someone can
gather the data I am happy to have a look at it.
