IKEA devices apparently work very well with Aqara

When it comes to zigbee devices, don't combine the aqara wall switches with large (4 buttons) ikea remotes.

The wall switches tend to execute the commands from the remotes instead of just routing them to the coordinator.

My Zigbee network also improved a lot when I set up some IKEA plugs in the loft.

I have similar experience with the ikea bulbs. More of them I connect, more stable the whole network gets.
