I had MQTT running flawless in my previous setup and now after reinstalling everything it keeps losing the connecion to the broker. So I removed everything:
uninstalled binding (is it correct that there isn’t any 2.x version?)
I installed the binding by adding “mqtt1” on the binding line in /etc/openhab2/services/addon.cfg.
Configuration is persisted in /etc/openhab2/services/mqtt.cfg
OH2 then creates config in /var/lib/openhab2/config/org/openhab/mqtt.config by itself.
BTW: You reinstalled the broker but is the service really running ? Or maybe the service is running but only bound to the local interface (127.0.0.1) ? I spent hours looking after “errors” like that …
I noticed indeed that the mosquitto service was not running properly: Active: active (exited)
I reinstalled the service via the openhabian-config menu and saw 2 errors:
$ sed -i /password_file/d /etc/mosquitto/mosquitto.conf
sed: can't read /etc/mosquitto/mosquitto.conf: No such file or directory
$ sed -i /allow_anonymous/d /etc/mosquitto/mosquitto.conf
sed: can't read /etc/mosquitto/mosquitto.conf: No such file or directory
So I created this file:
sudo touch /etc/mosquitto/mosquitto.conf
Afterwards I did a reinstall of mosquitto (again via openhiab-config) and the error were gone + service is running properly.
I’ve tested it via mosquitto_sub and mqtt.fx (for windows): everything looks fine
All actions which are wirkong with mqtt are working again. thanks!
Hey guys , Did you find a solution for this problem .
I have the same issue and struggle too get the service running.
Have tried different settings in .cfg file and config, even installed on a different machine and get the same error.
Can you guys help me out and give me some hints where to look.
