I have redone my system. MQTT binding is online. I am trying to get my shelly to work.It said online untill I entered the command and Stat and it went offline. I have looked everywher done everything I think needs to be done. Any ideas??
You encountered a frequent bug (about 100 forum posts 
) of OH 2.4. Restart OH after every .thing file change, or dismiss .thing config files altogether or update to OH 2.5M1.
Cheers
Ok all is good. The shelly ID on the shelly app states 2c7929 but MQTT.fx says 2C7929 and that made the difference!! It works!!!
