ZHA Zigbee change channel

DerekO · January 28, 2021, 1:59pm

I’m wondering this too - I’ve a Sonoff Zigbee Bridge running over ZHA and I’ve no idea what channel it is using, so can’t tell if it could be overlapping wifi, etc.

Here is a safe way (via logs, I did not spell it out in post, but shown below) and an unsafe way:

2021-01-25 09:04:00 INFO (MainThread) [bellows.zigbee.application] Node type: EmberNodeType.COORDINATOR, Network parameters: EmberNetworkParameters(extendedPanId=cc:cc:cc:cc:e3:ab:00:78, panId=0x3498, radioTxPower=20, radioChannel=11, joinMethod=<EmberJoinMethod.USE_MAC_ASSOCIATION: 0>, nwkManagerId=0x0000, nwkUpdateId=0, channels=<Channels.ALL_CHANNELS: 134215680>)

Hey @DerekO did you ever try modifying your channel? The HA ZHA page gives us instructions on how to push to a new channel. I’m hesitant because I dont really want to go through and re-pair all of my devices after the channel change. If I hear you did well with the push to the end of the frequency band I might do that as well. Here is the link to the instructions on moving the channel – plus I’ll paste the config instructions too:

DEFINING ZIGBEE CHANNEL TO USE

zha:
  zigpy_config:
    network:
      channel: 15             # What channel the radio should try to use.
      channels: [15, 20, 25]  # Channel mask

YAML

Copy

This is a good reference for channel selection Zigbee and Wifi Coexistance

@Liorm0505 I’m thinking the same thing as you-- but after pouring through the forums, some warned that not all devices can play in the full range of frequency bands. Im pretty lucky because I just have two vendors - so i can just test both. (Sonoff and Aquara). Any luck on your end? If it sounds like nobody has pushed all the way out to 26 maybe I’ll be the guinea pig.

No, I didn’t. After analysing what channels I’m using the ZHA network wasn’t a big issue. The Hue network was though so I changed channel on that, but with Hue it auto re-rapirs everything so it was easy (and made a massive difference to reliability)

My ZHA installation a while ago defaulted to ch 15:

2021-05-27 22:55:41 INFO (MainThread) [zigpy_znp.zigbee.application] ZNP is already configured, not forming a new network
2021-05-27 22:55:45 INFO (MainThread) [zigpy_znp.zigbee.application] This build of Z-Stack does not appear to support LED control

Will consider changing to 26 or 25. Morons in my neighborhood using channels 3, 5, 8 and 10. Doing that does not remove you from interference from 1, 6, 11…if anything it worsens it as now you get “noise” from both sides. WiMCA using ch 5 is overlaping my ZHA ch 15…

Hey, this was great help to get at least the Elelabs shield info, but I’m trying to change the channel and the terminal just gets stuck forever with no confirmation after I enter:

bash-5.1# bellows -b 115200 -d /dev/ttyAMA0 info 
[08:6b:d7:ff:fe:48:d2:b1]

EmberZNet version: 6.3.0.0 build 178
bash-5.1# bellows -b 115200 -d /dev/ttyAMA0 form -D zigbee.db -c 20

Any hints on what could be it?

I think you need to leave current one first.

Another option is to do a backup, change the channel in the backup file and then restore it and it will change the channel and retain all other settings. If you do this you may be able to just power cycle mains powered devices (leave them off for a minute or 2) and they may find the coordinator on the new channel.

adrianrdzv · September 30, 2021, 12:53am

You were right, I first needed to trigger “leave” and then I was able to change channel. Thanks!

Hi,
From where can you run this bellows command. I have HA running in a VM and have the SSH add-on, but once in there I can’t find the command.

This solved it for me and I am so happy i found it… 2+ years later.
Just got the SkyConnect and gonna migrate from my Conbee2 and Deconz.
I’m also thankful to everyone who actually read every word in the documentation… (lol)
Thank you!

You also need to “migrate radio” from the ZHA configuration.
Then “reconfigure current radio” → “select device” → “Erase network settings and create a new network”. You should still see all your previously connected devices after the reconfiguration in complete, but unfortunately you will probably need to reset and reconnect them all to update the channel and get data from them again.
Finally, you should see the channel updated in the GUI.

Yes things have changed since October 2020
