[Zigbee] ZHA Shows Network at nearly 90%. Help! | Home Assistant | Page 1

My zigbee Network shows utilization of nearly 90%. I have the zigbee adapter connected by usb extension. I now have 3 Zigbee repeaters around the house.

However, I do have a total of 55 Zigbee devices. Some already did connect to the repeaters, some did not. Yesterday I added about 20 new devices to the zigbee network…which probably caused the high utilization.
So, the only way to improve this situation is to get more repeaters, or should I switch the base Zigbee adapter that is connected to the raspberry? I am using the SONOFF Zigbee Adapter

Thx in advance

Zigbee channel 15 utilization is 89.94%!
If you are having problems joining new devices, are missing sensor updates, or have issues keeping devices joined, ensure your coordinator is away from interference sources such as USB 3.0 devices, SSDs, WiFi routers, etc.

Well have you checked interference? Is the coordinator away from interference sources? WiFi can interfere as well. Note that repeater is more of a WiFi term. In the Zigbee world devices that can route are called routers.

weak pike Well have you checked interference? Is the coordinator away from interference so...

I always mix up routers and repeaters. Sorry. I did move the WiFi adapter away from the raspberry as far as possible. However. The raspberry itself is connected by cable to a FritzBox Repeater…. Which itself is connected to the main Fritz Box by WiFi. But I wouldn’t know what else I could do to improve the situation. I wonder why some devices wouldn’t even pick up some of the routers… is there a maximum of devices that can connect to a router? (There probably is). If so, what would that number be? Thx in advance. My HA is relying a lot on Zigbee… so, the Zigbee network failing is a real nightmare

#

I also wonder… one of the SONOFF Thermostats, which is about 2 meter away from the main zigbee adapter is reporting weak signal (gray connection)… weird

#

… and the LQI for said SONOFF Thermostat is shown as 216… so.. actually that’s pretty good… maybe I am reading the colors wrong?

I don't know the limits at the top of my head. For generic recommendations see here: https://www.zigbee2mqtt.io/advanced/zigbee/02_improve_network_range_and_stability.html

I would ignore the message unless you're having issues

#

It'll be removed in the next release

Hi @silver lichen,
Is your zigbee located on a channel tht id being interfered with from WIFI. There are many zigbee channels to choose from. Some are much better than others.

Okay, its starting.... I get lots of dropped packets and heaters are off at morning... yikes

#

Will be getting another repeater today... hope it helps SOME.... I since did replace the USB extension cable with a isolated USB cable... doesnt seem to be of any help for now

#

The top right seems to be a capable repeater. Getting another one of that kind today... hope to be able to get some of the devices on the upper left to that new repeater. The bottom right is a cheap AliExpress repeater... which doesn't really pick up much it seems...

I'll now check if I can do anything bout wi-fi channel interference... but afaik our wifi doesnt run on channel 15... pretty sure it was 12 or something the last time I checked

So, from that I get that Channel 15 and 20 are most suitable while 26 could be nice but isnt supported by all Zigbee devices

#

my Fritz.Box router doesnt show channel 15 for the manual channel selection... it claims to be at channel 5 ....but the graphic also shows high channel usage... not sure if thats for another channel though

#

#

Zigbee channels are different than WiFi channels.

silver lichen Nov 12, 2024, 7:24 AM

#

Oh.... okay. So, what options do I have then? I thought I could toggle stuff on our router perhaps... if thats not an option then only repeaters can help?

#

wow.... the repeater picks up a lot of signals. I have to change some automations probably to help with performance a little... I do have 8 autoomations run at the same time every 15 minutes... should move those to be worked on in sequence.... though, that might only decrease spikes

#

No switching Wi-Fi Channel from 5 to 6. Answers on the net suggest that 6 on Wi-Fi and 15 on Zigbee can corelate fine

#

Changing zigbee channel would be my öast choice

#

Kind of. See metageek link.
