Looking at the documentation here:
MQTT topics and message structure, I see it is possible to get a graphical display of the Zigbee network. Search for this heading:
zigbee2mqtt/bridge/networkmapYou need to publish a message with the topic:
zigbee2mqtt/bridge/networkmap/routes and payload of
graphviz [Note
no {} around the payload].
This can take a few minutes and you will get a network map data published as a message topic:
zigbee2mqtt/bridge/networkmap/[graphviz. I didn't use this, I just copied the content of the message out of the zigbee2mqtt log.
You can then paste the message starting with
digraph G { and ending in
} into the panel at
WebGraphViz to get a graphical display of your network.
Using this I have confirmed that my INNR plugs work as routers. Having relocated one of the INNR plugs, I reset one of my temperature sensors that was in close proximity and I can now see that the sensor is routing back to the controller via the plug.
