NOT INCLUDED, but a very useful addition is the PIR Motion Sensor, which
powers down the clock when the room is empty.

GSP Time Receiver - easy to set up, buy needs to see a window

WiFi Time Receiver - A bit more involved to configure, but is more discreet and does not need to be near a window

Please add a note on your order to tell us if you want the GPS or the WiFi !

NOT INCLUDED, but compatible with our XTERNA Time / Temperature Transmitter:

If you want this option instead of the GPS or WiFi, please send us a message prior to ordering (£20 surcharge)
