Probably not the correct place to post this query but here goes. I'm currently heating a Cabin using a Heatmiser thermostat with built in relay, works well as a stand alone unit but I'm reluctant to shell out over £100 just to get the one unit to connect to the outside world ( and indigo). It occurred to me that since I already have an evohome system for the central heating that I might be able to extend this system to control an electric convection heater. But it doesn't appear that the evohome system allows for this. Any ideas how I might achieve this. One thought I did just have was to create a dummy heating zone and use this to trigger a Zwave relay to manage the heater.
I'm open to ideas.
