Good Evening,
since a couple of days my Zigbee Mesh is really bad. It seems that it gets bad since the Zigbee2mqtt Software Update on the HA ( the Update with the new UI).
Actually i use a Sonoff zbdogle-P Plus, it was really good before and now lot of bad lqi.
Im not sure but i think befor the endpoints conected to more than one routers.
Actually ive 73 devices in my network and i wanted to conect 18 more, don´t know what happend.
Does anyone have idea what could be the problem now ?
Hello Rainer T.,
Make sure you have a meter or 2 extension cable on the dongle and hang it away from any other computers.
Also make sure you are routing on any bulbs that get physically powered off. This messes with the mesh.
Hello, i use a USB 2.0 Cable ( read to better use them except USB 3.0) and my Bulbs ( Powerd devices) are connected, i´t worked well some days ago, don´t know what happen…
Is there a way to activate the routing ?
i got on every floor several powerd zigbee devices to let the endpoints conect, but i see just one conection from each endpoint to one of the bulb routers, and the endpont choose not the best router.
I really dont know.
I Mangade 2 months ago my zigbee to the sonoff dongle, checked the wifi channel and manged them away from zigbee channel, i use Channel 11 on zigbee.
I didnt change anything on my hardware, nothing…
Check here about interference with WIFI and other things to check. When I was talking about zigbee bulbs, it you use a non-smart switch to turn them on an off, that is sometimes a problem. The Home Assistant Cookbook - Index
Are you actually experiencing issues like delays in your automations, or are you basing everything on the new map in the frontend?
Asking because I noticed the new map shows only 1 connection to my coordinator after the update (there were loads more before). However, the network itself is working perfectly fine.
No idea whether this also affects LQI values because I don’t really pay close attention, but it could be just a visual thing if everything seems to be working normally.
Good morning,
I use Shelly behind my Switches and normal LED Lights in my house, most of the shelly are Wifi bit i placed aware 10 Zigbee shelly in the house to gat a stable zigbee network, i also got 9 RGB-LED Controller working on zigbee to get it more stable, they are on power plug and work as router. All my end devices should have near router to connect, and when i check the map in Zigbee2mqtt i see they use often a router farer away and i got slow reactions now.
My wifi is manually manged with the channel’s, ive an asus rog router and 3 lan connected access point, all with different channels and away from the zigbee channel, ( i know zigbee channel isn’t same frequency like wifi :), i just got one neighbor and his wifi is far away, so this cant ne the reason i think, and it was working much better before the update.
And yes, i also see just one connection to my coordinator, and that router akso has just one connection to the next router, dont know why, before there were several connection between routers and between coordinator and routers, now just one…
It seems that this comes with the update. Thats really annoying because i built my system based on zigbee, even my alarm system is working with zigbee sensors on windows and movement detectors also so thats not funny.
I try to connect an enddevice manually to the nearest router ( allow to join only on one router) and that helped a bit i got better lqi and faster reactions, but at least shouldnt the mesh do it by itself? And why is just one router to coordinator, i could understand that that makes the system slowly now. Is there a software side possibility to tell all devices to reconnect and see if it works better after ?
80 devices manually connecting is a big deal and not the idea behind the system i think. Hopefully there will be a better solution than manage a automatic system manually…
Any news until now?
My zigbee network still is really bad and I’m afraid mounting my other 20 zigbee movement sensors…
Z2M is running on channel 11 — same as my setup.
I also configured my 2.4 GHz Wi-Fi to channel 11 with a 20 MHz bandwidth to ensure the cleanest spectrum possible.
In theory, this should avoid interference between Zigbee and Wi-Fi.
Did you try stopping Z2M for a short period (around 2 hours) to force the devices to rebuild the mesh?
Sometimes this helps routers and end devices establish new and stronger routes.
