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.
Flirc cases are nice, but the rubber parts do not handle the high temperatures well.
One of my pis is running inside a cupboard, so not ideal in terms of ventilation. The rubbery top and bottom of the case has started to dissolve into a sticky oil that was a bitch to clean up. The plastic underneath looks OK, so once the rest of it dissolves it will look normal again.
The other pi with the same case that’s out in the open shows no signs of degradation.
