Found some old elro on/off switches, thought they would be similar to the AB600. The remote AB600R doesn't work anymore, so no learning mode.
Sticker at the back mentions AB600SB, but ARC doesn't seem to do the trick.

Anyone know the difference between the AB600 and AB600SB? And if possible how to get it working with the rfxcom?

tip from Bert

is the same as AB600
use ARC, set in learning mode and link by sending multiple off commands.
