Hi folks. I'm looking for general help with my Zigbee network. I'm running a Z2MQTT server, have an SLZB-MR2 coordinator centrally in my house, have about 150 mains powered devices throughout the house... but my link quality is terrible (the median LQI is about 90, I think) and the network refuses to pair anything new. If I try to view the nework data in the "Network" tab of the Z2MQTT UI it just shows "Loading..." with the (depressingly appropriate) infinity animation and never returns. I'm struggling to figure out how to diagnose/debug this thing.
