OK, some kind of forum software restart. Maybe posts will work now...

What's the difference between a T87RF and a Y87RF? I want to add a wall sensor to my existing Evohome. Looks like Vesternet have got good prices on the T87RF.

Y87RF is a wall thermostat and BDR91 relay bundled together intended to be used as a standalone system. (Although you could still use them both with Evohome if you cleared the bindings and you happened to want a BDR91 for something)

T87RF is the wall thermostat by itself and is therefore cheaper.

Thanks. T87RF ordered from Vesternet.

If you look hard you can sometimes find a Y87RF for almost the same as a T87RF, you get a free BDR91. You sell the free BDR91 and then suddenly your T87RF becomes very cheap!
