Every time I think everything is working perfectly, I get this old issue back again.
Zigbee2mttq interface stops loading. Some Zigbee stuff works, other Zigbee stuff doesn’t. EG, one Zigbee remote controls Shelly stuff, but not Zigbee sockets (almost like it’s gone simplex!).
It’s driving me mad, it’s like an emotional rollercoaster
I’ve reimaged a thousand times (I mean, exaggerating, but not much). And even tried different hardware. What sometimes fixes it is reapplying a snapshot (with the config it was using anyway!). A reboot doesn’t usually help. I don’t think signal is an issue as the map looks fine (when it loads ok!), and most of the affected devices are within a few metres from eachother. Pi is hardwired, and close to the devices.
Set up is rPi (4GB), ZZH (on USB extension), Zigbee2mttq, Node Red
A list of common error codes and what to do in case of them:
MAC_CHANNEL_ACCESS_FAILURE: this happens when the wireless spectrum is too occupied. Mostly happens when a microwave is on or when there are WiFi networks on the same channel. See Reduce Wifi interference by changing the Zigbee channel how to fix this.
