Man, there’s no sneaking anything past this community
What you are seeing is a side effect of some work I did back around the 0.25 release laying some initial ground work for us to explore potential tools to more easily debug Zigbee connectivity/mesh/device issues. I can not confirm or deny if this involves a Zigbee mesh diagram and/or routing table
These events would have started to show up in the IDE event logs with the most recent hub FW update and to be entirely honest this was not an intended feature. I would not expect them to stick around long term as these messages can be very misleading and on their own do not provide enough information to understand how your Zigbee mesh is routing messages.
