Seems like I have exactly the same issue (Zigbee not pairing, athom not responding ), have you been able to resolve this?
Somewhat I did resolve it. And I would say that my solution is a combination of everything that has been suggested by @Peter_Kawa and @robertklep so I cannot really pinpoint one single factor.
In summary I have:
- reinstalled the Homey with “full software download”
- changed the original power supply with an iPad charger
- Added more repeater (a few Ikea Tradfri and a couple of Aqara plugs)
- reset and rebuilt the Zigbee from scratch
I am still in the process of reconnecting all the zigbee devices (the infamous Temperature Sensors are now connected) but overall the network seems more stable and reliable so far.
The only thing that I was not always able to do as suggested, is to pair every device to its nearest repeater. With some devices, no matter how many times I tried, it simply doesn’t work. In those cases, I paired them with homey directly and then placed them in their final location. It seems that the network adjust itself after a bit anyway.
Hope this helps.
And thanks again to @Peter_Kawa and @robertklep
