Immersion heater WiFi timer

Can anyone recommend an immersion heater timer (or just a device to turn the heater on and off) with WiFi (preferably) or Bluetooth interface?

is insanely expensive - but the self contained nature might appeal.

Or, the other day, someone mentioned LightwaveRF - you'd need 2 devices:

that comes to half the cost.

Slightly better than plugging the immersion in would be to swap the socket above for:

use that to drive a heavy duty relay for 13A control (crimp/solder flex onto the relay, heatshrink connections, put in box, use glands for strain relief.

Thanks very much for the useful info. As you say, this is very expensive; but it seemed the only device among those you listed which told one the actual temperature of the water - that would be useful, though not essential.

I suppose an app on a phone or desktop which acted as a timer would not be too difficult to set up.

Should be straightforward with the Lightwave stuff if you don;t mind a little scripting.

RPi with a USB wifi dongle perhaps?
