I use the Visualization under Device Info/Zigbee Info/View Network to see how devices are connected to each other, but I not sure what the line numbers mean.
I see some lines with a single number. Some have 2 numbers like 103/70.
I assume the line color of Red, Yellow or Green is some qualitative measure of some connectivity value…but don’t know what it is.
Can anyone tell me what they actually are? Is there documentation on this? Is there a better way to view this information?
Thanks
This is from Zigbee2mqtt’s map:
I assume you are using ZHA by the description you gave, but it is similar.
I believe the ZHA “network visualisation” was originally a dashboard card. It was absorbed into ZHA and the card is now deprecated, but the repository is still on Github with an explanation of the colours and numbers.
Probably not… and it’s of limited use in any case. The routes messages take across the network change, you can’t control them. The numbers represent LQI values, which are a measure of error rates (higher is fewer), but they need to be taken with a pinch of salt. I have a sensor with an LQI of 0 which still works most of the time.
Each Zigbee device should have an LQI sensor (disabled by default in ZHA) which you can put on a dashboard if you want to.
The map can give you a feel for the health of your network, but don’t obsess over it. 
Yes I’m using ZHA, I should have said that. There are no dashed lines ow star for coordinator, so may not be same as mqtt.
Thanks for the link to github…answers some of the questions.
I would LOVE to get hold of the LQI for my devices. Right now I have to manually go the the Device Info in the 3 vert dots and manually grab the number. Maybe I can figure out how to enable the LQI sensor LQI and solve the problem!
You just have to enable the diagnositic sensor. It is disabled by default. See: HA 11.5 Dashboard with LQI? - #2 by tom_l
Don’t be alarmed if LQI values for battery operated devices are unavailable. They only report at intervals - it can take half an hour or so for them all to check in after a restart.
This is working very well for me. I was getting Unknown for the value of LQI and almost gave up, but if you display the LQI in a graph card, you get a GREAT chart of the time evolution of real-time LQI, including shaded bands, I assuming the range of LQI during that data sampling time. RSSI doesn’t seem to do the same and may not be doing anything.
You’ll likely get more responses if you ask in the Zigbee forum.
That was my fault. Moved it to the correct category this time.
Thanks for the info. Fortunately the folks here gave me all the info I needed to stand a long-standing problem I had to monitor LQI like a battery for my devices.
Thanks to all for your help!
