I’ve been experiencing repeating issues in #HomeAssistant with devices not responding. It’s been manifesting in the system log as an error:

cp210x ttyUSB0: failed set request 0x12 status: -110

That’s Zigbee dongle. The workaround was to reboot the system, but I’ve changed it’s USB port and it seems to be gone.

The system is #RaspbianOS on #Raspberry Pi5. Pi is powered via PoE and it should have sufficient power budget, though it’s running of an nvme.2 and with USB hard drive, so who knows…

@ssamulczyk If you still have issues and you haven’t yet also consider putting it on a USB extension. Plugging directly into the USB port can cause interference issues. I’ve seen and others have reported this.

@GavinCampbell It’s already on a long-ass extension, because otherwise it would have been hidden and crammed along with 2 Pi’s, router, switch and modem… Way to much interference!🤷🏻‍♂️

@ssamulczyk Nice. Well that eliminates that issue. :)

@GavinCampbell I’ve also had, for a brief time, a separate Ikea Tradfri gateway.

So I had 2 Zigbee networks competing for the already narrow band…😂

That is some finicky shit, but when you do it just right, it works. I have 40+ Zigbee devices and that USB error was my only remaining issue…🥹

@ssamulczyk I’ve been through a number of controllers. Right now I have the Home Assistant ZBT-2 as my primary zigbee with the Aqara M3 for my legacy Aqara devices. I also have a ZWA-2 for zwave and another ZBT-2 for thread. That’s a lot of signals around my house. But it has never been more stable.

@GavinCampbell At least it’s all 2,4GHz… Also, sounds like a real nightmare to diagnose in case of a failure… Can’t imagine swapping controllers, as I think the data of the network is held on the controller.

I’ve once, accidentally, changed the controller’s channel and it took me hours to bring it back to normal…🥹

For me - a single network - was between either Zigbee or Z-Wave. Zigbee is just less expensive and there are more DIY things…🥸

@ssamulczyk Swapping controllers is a pain. I have a few hundred devices. Zwave is much easier with newer firmware you can back up and restore. Zigbee always was a pain and still haven’t really perfected that one. But with these controllers I’m now happy. I eventually want to get rid of the m3 but that may require replacing some devices too.
