Question about my strange conbee zigbee mesh

see below screenshot
in phoscon i have 5 x osram plug (2 not connected), 4 x xiaomi motion sensor, 2 x ikea remote switch
the 2 x osram not disconnected, is normal

  1. The other 3 x devices , i have no idea what they are, they are not in phoscon also?
  2. on every floor i have a osram to repeat the signal, so why are all my xiaomi sensors connected to the conbee, while the osrams plugs are nearby, thats my issue with the 4th xiaomi sensor, it disconnects soemtimes, i dont know why it doesnt connect to the osram plug , thats a few feet away?

Not all zigbee routers are able to route/repeat all zigbee devices. Are you sure the osram plugs are compatible?

I use tradfri plugs, and a range of bulbs which my xiaomi sensors are happy to connect with. What happens if you take the battery out of a sensor, turn off the conbee and replace the battery before turning the conbee back on? (some sensors you can press reset briefly rather than removing battery).

yes, the osram are repeaters, i know because first i had ikea pir sensors, replaced them by xiaomi
the ikea pirs were linked to osram without a problem

ok, gonna try the reset stuff

dont get it actually, the conbee is 2 floors upstairs, downstairs there is also a xiaomi, with an osram verry close, but it searches the conbee 2 floors upstairs instead

ok, seems the 4th xiaomi is now linked to the osrman instead, so thats resolved

still dont know those 3 devices, those are unknown to me? whats that all about?
