Devices continuously dropping off my ZigBee network (lemm.ee)

I recently setup my ZigBee network in Home Assistant, using a Conbee III with deConz on my Synology NAS.

I purchased a few Aqara Temperature sensors and a couple of Mini Switches.

I was able to get them to pair just fine, but they won't remain online for more than a couple days. They then drop off and I can't even reconnect them easily. I need to try to pair them again like 10 times before they come back online.

At this point I don't know if the problem is my network, the Conbee III, deConz, or the Aqara devices.

I don't know much about ZigBee, but a couple things that I tried so far were:

  1. Use a USB extender instead of connecting the Conbee III directly to my NAS.
  2. Bring the devices as close a possible to the gateway. I don't have a big home, so I don't think distance is a factor here, but still, I put of the sensors right next to the gateway, and it would still drop after a while.

Do you have any hints on things to try to get this fixed, or at least identify the problem?

I had issues with my Aqara temperature sensor dropping out within hours of setting it up, sleuthed the internet a bit and found that it worked better if connected through another Aqara device. Set it up through "Add devices via this device" on my Aqara smart plug through ZHA and it hasn't dropped out in weeks. Would've thought it worked the same as just adding it regularly but apparently not.
