Hi all,
I have a Fibaro FGS-223 double relay switch in one of my rooms. This switch is behaving unexpected, but I can reproduce it 100% of the time.
I have two changeover switches in the wall, at both doors of the room. Before adding the Fibaro switch, they work as expected. Left button on both sides operate light 1, right button on both sides light 2.
Since I added the Fibaro, I have a weird scenario. If I switch both lights on on one side, the other side crosses the switches. I need the right switch to turn off light 1 and the left to turn off light 2. Has anybody seen this before? Have I wired the Fibaro wrong?
I'm tempted to change the Fibaro to a TKB Home double switch I have in spare.

It really sounds like you miswired the switches. To help us help you, could you sketch up a little diagram of how you wired the switches, possibly include some photos. If that doesn't work, please explain what you changed in the wiring when installing the fgs-223.

Plus, can you confirm that my understanding of the old situation is correct: you had 2 double switches, both controlling the same 2 lights. If I am right, these switches all had 3 wires coming from them. On one end there were 3 black wires on each switch, on the other there was 1 brown and 2 black wires on each switch. If I am right, these were 2 hotel switches, one for each lamp.

Guessing from your name, you will not have a problem reading Dutch, so here is a link explaining how to make a hotel switch smart: https://www.robbshop.nl/domotica/projec ... schakeling. In short: to make a hotel switch smart, you leave the complete hotel wiring unchanged, you only add the fgs-223 between the switch with 3 black wires and the light bulb. The switch connects to Sx, the light to Qx. You'll have to do it twice, connecting one circuit to S1 and Q1 of the FGS-223 and the other to S2 and Q2.

I took one of the wall switches out today and tested all wires. Seems I twisted two when I put the wallpaper up a few weeks ago.
Everything is working fine now, wall switches and Fibaro are acting like they should.

Thanks for the help.

Well done!
