Switch HmIP-BSM on

Dear all,

I have a quite simple plan: I installed an IKEA motion sensor in a room which is using an HmIP-BSM for light control.

Now I want to use the motion sensor to switch on the light, but I cannot find the correct entity or device. The device is simply called “Lichtschalter” (switch.lichtschalter) in my overview panel, but when the respective automation (“Motion-activated light” as shipped with Home Assistant) is executed, nothing happens.

Would you have a recommendation?

Thanks,
Tobias

Is there a specific subcategory for HmIP-related questions? I’m quite sure some more advanced user can easily help…
