@sudden quiver I'm a bit late to the party. But I'm struggling a bit, I run on Home Assistant Core. How to get this python script to work when I'm on HA Core?

sudden quiver Use https://github.com/zigpy/zigpy-cli#changing-the-network-channel instead

I can't get Zigpy to work on HA core

Save this script as something like change_network_channel.py within your /config/ folder: https://dpaste.org/KOAHo

#

@quasi cliff then run it just like you did the energy scan tool: python /config/change_network_channel.py -v --channel 20 /dev/serial/by-id/...

#

None of your battery operated devices will migrate (though some could!) but I just tested it with a small network of a ZNP coordinator and a few bulbs and they all switched channels after ZHA was restarted

#

If you have any battery-powered devices that are practically impossible to rejoin due to location (and aren't Aqara) it's in theory possible to modify the script to migrate them as well, but it'll require a ton more effort

#

@sudden quiver thanks! I've saved it, I'll let you know how it went

#

and it's great, if this works, It'd save me a lot of effort anyway

sudden quiver Jun 12, 2022, 5:17 PM

#

Sounds good. There's no way to view the current channel within ZHA so run a network backup afterwards just to triple check

quasi cliff Jun 12, 2022, 5:17 PM

#

rejoining a few sensors is not that much of a bother in comparison

#

will do!

#

tbh most of my sensors are aqara lol

sudden quiver Jun 12, 2022, 5:19 PM

#

Yeah you're out of luck with those sensors, they're effectively send-only devices after they join and don't implement this part of the spec to begin with 😆

quasi cliff Jun 12, 2022, 5:20 PM

#

lovely!

sudden quiver Jun 12, 2022, 5:21 PM

#

But now that they've joined it should be very easy to re-join them, since ZHA knows all it needs to know about the device

quasi cliff Jun 12, 2022, 5:21 PM

#

just the matter of finding them physically.

sudden quiver Jun 12, 2022, 5:22 PM

#

One thing to watch out for is that they can get into a state where their battery has just enough juice to send periodic reports, but not enough to actively scan for and join a new network. You may have to change batteries if you've been using them for a few years if they don't seem to reliably re-join.

quasi cliff Jun 12, 2022, 5:22 PM

#

yes, I did notice weird pairing behaviours depending on battery level...

#

welp, a round of general maintenance with fresh batteries for the network won't hurt

#

thanks again

sudden quiver Jun 12, 2022, 5:24 PM

#

And Aqara sensors don't have reliable battery reporting to begin with so you just gotta check by feel and how alive the blue LED looks 😆

#

No problem, let me know how it turns out

quasi cliff Jun 12, 2022, 10:13 PM

#

Worked, thank you!

#

lost all battery operated buttons, aqara opple and ikea, a couple of thermo sensors, and a single bulb, for some reason

#

a tuya battery operated thermostat held out though

#

the only reliable way to get them back for me is to delete the device from the integration and rejoin, but still, not a big deal all in all

#

thanks again 🙂

sudden quiver Jun 12, 2022, 10:17 PM

#

Thanks for the feedback!

#

You should be able to just permit joins and reset the device, without having tor remove it

quasi cliff Jun 12, 2022, 10:18 PM

#

i tried handle_join and misc_reinitialize from the zha toolkit, calling the devices via ieee, but that didn't work

#

ah, i see, there's zha.permit

sudden quiver Jun 12, 2022, 10:20 PM

#

Just the + Add Device button is fine

quasi cliff Jun 12, 2022, 10:44 PM

#

yup, worked fine 🙂
