Cannot connect Aeotec Multisensor 6

This device should work: https://www.domotica-blog.nl/post/review-aeotec-multisensor-6/homey/

But try this:
Power down the Homey wait 20 min then power back on and add the device once more.

Very old topic, but I am wondering if it worked. I am having a very hard time including 3 Coolcam sensors.
