I’ve been running Z2M for over a year with minimal issues. Recently, all my motion automations stopped working (all of my motion sensors are zigbee). I researched, and zigbee2mqtt was stopped. I started it (or pushed “start”) in the UI and it wouldn’t start. I checked the logs, and it said it was “started”. I click back from logs to the main page to try again, and it said “this addon is not running”. I messed with it for quite some time without progress. I tried resorting to a backup from a couple days prior (when it was working). Same thing. As things have progressed, I’ve uninstalled Zigbee2mqtt, I’ve gone to backups from 2 weeks ago. Uninstalled mosquito broker, replaced my sonoff usb 3.0 plus p coordinator, replaced the USB hub and extension cable. I’ve restarted the VM, and restarted my unraid server. I will occasionally get it to start (turn green); and can actually get into the webui (sometimes), but when I do, all my devices are “offline”. Sometimes only the hard-powered devices show online. If I try to “permit to join” it will freeze up and go offline again. I’ve deleted the zigbee2mqtt folder, restored the config file, started fresh with a new file, regenerated pem files, changed network keys in teh config file. It doesn’t seem to matter what I do, I can’t consistently get it to stay running. At this point I’m “ok” with completely restarting from scratch with the Zigbee stuff, but can’t fathom starting over with a new HA instance. It seems like I’ve eliminated software possibilites and also hardware issues. There are NO errors whatsoever in the logs (even when it stops), so I don’t have any clue where else to go to resolve. Any help is appreciated.
Try reflashing the firmware on your stick.
Sorry, I should have mentioned, that I tried that as well and also tried a completely new stick
