Hi,

I have semi-successfully converted my OH1 setup to OH2 snapshot build 159 using the addons from OH1 build 921 .

The mqtt binding is in addons, and the transport itself should come with the OH2 core if I understand things correctly. Also, I took the necessary part from my old openhab.cfg, and put it into services/mqtt.cfg, removing the "mqtt:" in front of the keys as described in https://github.com/openhab/openhab2/blob/master/docs/sources/installation/runtime.md

I did the same for NTP, onewire and a few more bindings, which I can use successfully.

For MQTT, I see no output in the log file that this particular service is started, neither can I see a connection being made to my local mosquitto server.

So, the question is, does someone have OH2 with MQTT already up and running and could give me a hint or should I expect MQTT to be not running at all at the moment (and switch back to OH1)?

Regards,
Hakan
