They shouldn’t reside at the outside “ring” of your zigbee devices, you should place them somewhere half way Homey and the farthest sensor.
.
My Aqara sensors stopped sending updates after I added Ikea lights.
Issue with Homey zigbee: as soon as an Aqara sensor starts to use an Ikea lamp as router, it stops sending updates, AND it doesn’t look for other routers or the controller anymore.
It’s very likely your Ikea light is causing the same issue.
I’m under the impression this years old bug won’t get solved by either Ikea or Aqara (plus, Ikea now is completely into Matter, they might hope the issue fades over time):
.
Interesting fact:
With zigbee2mqtt and my Ikea + Aqara devices this issue isn’t occuring.
