I have a fairly decently sized ZigBee network (around 80 devices, half mains powered / routers, half end devices).
Moved to the ZBT-2 from the Sonoff ZBDongle-P using Z2M purely in hopes that it would solve a couple of range issues. Migration was a bit of a pain, but got there eventually, for around 50% of the time, the network performs much faster (and my range issues are resolved), however I now face a new problem where packets are not being delivered to the coordinator consistently, almost like the whole thing locks up for a few moments, this means some of my lights take an extra 30 seconds to actually come on (or they don't come on at all) with constant delivery timeout errors logged in the logs until suddenly it comes back to life for a unknown number of messages.
Has anyone had similar? Or noticed any improvement when using the 8.x.x firmwares? At a complete loss as to how I can solve this, moving the ZBT hasn't made any difference, nor changing usb ports etc.
