Last night, as I was sleeping Tasmota just stopped working. All the devices stated it there were unavailable. I double check MQTT and SetOption19.
I then uninstalling the integration, reinstalled it, and now, none of the devices are being recognized so I can’t add them.
when you access them using your browser,
What do you see in the console log?
normally when there is no connection to HA it shows something.
Also, have you tried restarting your wifi accesspoint?
and just to be sure, SetOption19 should be “OFF”, not “ON”
Disconnected from MQTT server core-mosquitto:1883 (5)
10:32:24 AM – (WARNING) MQTT - message first occurred at 8:20:04 AM and shows up 73 times
Unable to connect to the MQTT broker: Connection Refused: not authorised.
10:32:24 AM – (ERROR) MQTT - message first occurred at 8:20:04 AM and shows up 73 times
Could you recreate the user in MQTT?
or create a new one?
so, after spending half the day on this… somehow in the middle of the night, when nothing was stirring, not even a mouse, my mosquitto broker integration wiped itself clean. I am thankfully back up and running
