Hello,
I have 2 z-wave bulbs with 1 wall switch that i want to include to my z-wave network.

I clicked include on home assistant an tured on an off the wall switch 3 times, but only 1 bulb was includded.

Is it possible to include the 2 bulbs at the same time with the same wall switch?

Hello all,
Anyone with an idea for solution?
