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?

well... that sucks!

I am looking for online master degrees and came across TECH, with an incredibly granular offering and excellent reviews in sites like Trustpilot or Emagister. Their prices are also very competitive.

The more I tried to find information about them, the shadier things looked. The vast majority of the opinions about them are very favourable (suspiciously so), but some are straight up scam accusations. No middle ground.

Has anyone had first hand experience with them?
