I have OH 2 latest snapshot MQTT installed and configured successfully Item configured to receive a message from a topic and parse using JSONPath Item: String PresenceJF_Phone “JFHome” { mqtt=“<[mqtt:openHAB/in/jfiPhone/state:state:JSONPATH($.lat)]” } On my iPhone I have owntracks installe…

Seems like a service restart has resolved the issue.

update - as soon as I open the Owntracks app on iOS (or switch to the app) this error occurs. I don’t need to manually press the publish button for it to happen.

My guess is you are using the same clientId for both connections (phone + openHAB). The broker will drop one of the connections if another attempt is made with the same clientId.

Thanks for your reply. I’m using “oh” as client for openHAB and “jf” for my phone - unfortunately that doesn’t seem to be my issue.

I just restarted the Mosquitto service and kept an eye on the Mosquitto log file. In there I noticed this: 1477050274: New client connected from 127.0.0.1 as OpenHAB2 (c1, k60). 1477050278: New connection from 192.168.5.3 on port 1883. 1477050278: Client OpenHAB2 already connected, closing old conn…

You need to use different clients from different devices. I use two different users, one for OpenHAB and one for Owntracks. You need to create a few users for mosquitto and use a different one on each “client” Unless in this case it’s just mosquitto resetting the connection because of the OH resta…

OpenHAB has a unique client name. I’ve just changed the name in mqtt.cfg but didn’t see the new name come through, so I’m restarting the OpenHab2 service now

Odd - In services/mqtt.cfg I changed the client name to be OpenHAB_2, but I still see the client name as OpenHAB2 (as it was before the change

I found that for some changes I have to completely restart service and sometimes reboot. I also moved away from using my Pine64 to using a more powerful VM - MUCH quicker to startup! (off-topic, I know)

Even after a reboot of the Pi I’m still seeing the same OpenHAB2 client connect. It would be great if I could track down where in the config this is set. I’m not seeing anything if I run grep on the /etc/OpenHAB2/ directory.

MQTT Connection lost every time an update is pushed
