Maximum # devices on zzh stick with zigbee2mqtt?

Configuration Zigbee
1

I have 114 devices now connected to my ZZH stick with zigbee2mqtt.
I have 3 dedicated zigbee routers but also half of the devices are bulbs and sockets that also act as router.

With this number I experience that devices randomly loose their connection and need to reconnect with power cycle or repair.

This looks similar like when I got more then 40 devices on the basic CC2531 stick until that became unstable. Does that mean that I have reached the maximum for the ZZH stick?

Are there people with more devices connected to this stick or experience the same?

In our experience, more than 150 devices on the CC2652 cause significant delays. Therefore, it is better to divide the network into several segments. In the case of simple sensors with rare data sending and a small number of clusters, the network will work up to 200.
