[ProjektC]

Hi

- New SD Card
- Current Raspberry installed
- All updates and upgrades
- Last stable Domoticz version installed
- Domoticz is started
- Domoticz finished via putty
- Plugins and scripts copied from backup
- Last db database imported

Now Domotizc starts only always offline

bye

from wiki https://www.domoticz.com/wiki/Raspberry_Pi :

WARNING nov 2021: Raspberry Pi OS based on Bullseye is giving issues with Python plugins on Domoticz 2022.1 Stable!! Please do not upgrade or use this OS version for fresh install (instead use Raspberry Pi OS Legacy, based on Buster). Other option is to move to Domoticz Beta version as it is solved in this version.

This has something to do with MQTT.
Have installed it but unfortunately it does not work

2022-09-28 18:02:08.076 Error: SellyMQTT: Disconnected from MQTT Server: 192.168.0.184:1883

That error would not set Domoticz offline.
Is your Domoticz crashing or is it still running but you cannot connect? Did you clear your browser cache as that is the most common solution for user interface issues. Try to access Domoticz with your browser in incognito mode to check.

Perhaps a firewall blocks port 1883 ?

This was all working so well and now I can't get it to work after hours.

It is a fresh Respberry installation

sudo systemctl enable mosquitto.service

I don't understand why this does not work

So now Buster installed but has brought nothing.
listener 1883
removed and then it worked

There are unfortunately many sites that write even with 2.0.11 it must be in.
