But to your problem - which wire is which -
12V - 12V supply for powering infra red detectors etc, not required for a standard switch, or for an illuminated switch.
Grd - Ground. This will definitely be one of the two wires which will be used for your switch.
Sens- not sure. probably sensor, as in motion sensor
My guess is the trigger for the infra-red.

St - Probably start. My tip is that you would install your switch between this and grd.
My thoughts too, I just wanted to be sure.

You mention a diode on the other switch. is this diode actually on the
switch, or on the circuit board after the st connection? If it's after the connection, it's probably a protection device to save the circuit board in the case of an incorrectly wired switch (eg 12v to st instead of gnd to st.).
It's on the board after the ST connection.

Do you know an installer...
No.

The company is unlikely to tell you (protecting their installers) if they haven't already put it in the owners manual.
Gliderol haven't replied to any emails I've sent them.

Personally, I'd give short Grd to St with a jumper wire or a pair of pliers, but I won't advise you to do this as I don't want to be responsible for you frying your board, even if that is an unlikely scenario.
Just what I didn't want to do by trail & error, which is why I asked the question.

Remember any switches you do add need to be "momentary" switches, not locking switches. $5 at an electrical wholesaler or an electronics shop will get you a "bell press", which is a switch/button for a doorbell. Exactly what I used for one of my grandparent's extra switch.
Already got a 'bell-press' lined up to do the job, just got to find out which connections to hook it up to.
Thanks Dean.
