hope everybody is well. This is my first topic here: I am currently equipping our new old building with Shellys. Most of the equipments are Shelly Dimmer 2. So far they work pretty reliable, however today I have connected the Dimmer 2 to a Motion Sensor (Steinel 180-2), and although the motion sensor picks up (I checked voltage) it is not activating the Dimmer.
I tried all button settings; neither work. On some web pages I was reading something about an additional relais? Why would that be needed?
Hope somebody can support, many thanks in advance.
