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?

Once everything is online have you checked the network map to see how it's all connected? That might give you an idea. If everything is connected directly to your gateway your problem is probably there. If it's all bridged through one relay device that device is likely the issue.

How can I see how everything is connected or check the signal strength at the devices?

Devices and services, click on your Zigbee integration, configure, then network. Not sure if it works the same way for all the integrations, but that's how ZHA works. I know z2mqtt has a network map as well.
