ZigBee on channel 11, wifi on channel 11, same number but not the same frequencies. There is only one other wifi signal I can see from my neighbor but very weak.
The problem : every couple of day I have to re-pair some battery devices that lost the network. Their LQI is ok, battery too, for some of them (ex temp and humidity sensor from aquara) I just have to click on the button without repairing and it’s ok, for others I have to put the whole network on pairing mode and pair them again.
It’s really annoying, I don’t know what to do too fix this. All devices are close to at least 2 or 3 routers (less than 5 meters).
When as the network last working as expected? Remove everything added since then, then pair them again one at a time, waiting about a day between each to see how the network shakes down.
If you can identify where the problem started you’ll be nearer to knowing what it is.
What does your device map look like at couple points in time? If you can capture a snapshot of your device routes when one or more of these problematic devices are connected, are they in fact connecting via your router devices or falling back to connecting directly to your coordinator.
Not being able to capture a device’s ‘route back to the coordinator’ over time and seeing any changes is a real shortcoming in both ZHA and Zigbee2MQTT.
OK. So you’re asking for help troubleshooring a network that has never… er… worked.
LQI ratings don’t mean much - different manufacurers generate them differently and in any case they change all the time - but as an overview I’d say that those in the snapshot you have provided are a bit low.
Here’s mine for comparison (not trouble-free by any means, but nearly all would count as at least “yellow” connections - 129-192 - on the ZHA map):
The co-ordinator is in the study, and LQI ratings there are high, as are those in the rooms directly above (bedroom) and below (living room). The weakest ratings are in the kitchen, hallway and landing areas, all of which are in a newer part of the building separated from the rest by a thick wall.
If you can generate an overview of your own home, associating LQI ratings with areas, I still think there will be places where additional routers will help.
Thanks for your help, I’ll do this kind of dashboard, it may help. About my network it was probably ok 6-7 years ago with a couple of devices but to be honest I have this kind of problems for at least a year or two now and I recently started to make it more stable (adding routers, changing wifi channel, force connect to closest routers )
