UnderFloor Heating Thermostat LCD Touch Screen Programmable with Floor Sensor Z-Wave-Enabled Device (for Electric Heating System, Black)

This product works well with Smartthings and with electrical underfloor heating. The only issue I have is the large back box which does not fit in gap it replaces in my home, meaning I'll need to get a wall chased out in order for it to sit flush. But otherwise, it's pretty brilliant for the price.

Love this, simple to install & straightforward to set up. Price point was excellent. My only quibble is that one of the legs on the wall plate broke so it was a bit wobbly until darling husband sorted it out.
