Hi Kevin, I also have a themostat project in mind, unfortunately it's not central heating but baseboards. I'm sure it can be done but not how or what components. Am not a programmer nor an electronics person. The base idea is a wifi enabled raspberry pi controller, remote wifi temperature sensors and wifi enabled 120V switches Replace the variable heat control dial on the baseboards with the on/off wifi switch, should be able to handle 10 amps. Put the temperature sensors across the room at sitting height. Have the central control programmed to 1) sample the temp sensors sequentially perhaps 1x/min, 2) if temp below a given threshold turn on that room's heater above another threshold turn it off (ie if your temp setting is 20C turn on if <19C and off if >21C to prevent constant on/off cycles) 3) have time based settings for time of use electric rates which the current crop of programmable thermostats other than something like the uber expensive Nest can do 4) be able to program different temperatures for different rooms based on usage. As you have already done some work on this can you suggest components. I am a complete neophyte with this kind of thing. Any direction would be most appreciated! Nice project by the way!

Hi John

Thanks for the comment I was considering the Ciseco Slice of Radio SC13019 but as the hardwired connection was already there to the boiler I went for that. I have two of the boards and will be thinking of a new project for them [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-79b3180d-0bed-4732-ab93-6f22860d41ed/contentimage_5F00_1.png:16:16]

Nice wee project, nice to see you are using a Ciseco product, they produce some nice kit.

You may want to look at their RF kit for the Pi/Arduino which all use the Chip Con C1100.for say a thermostat

That's now a TI part and very useful indeed, I'm trying to finish off some videos showing their worked examples

for the RasWIK kit but so far only got the first one done ...
