Now that I have made peace with the fact that the new mqtt binding is the way to go it is time to make things a bit easier.
I have quite a few SonOff Tasmota devices and have to add them all to my system.
Keep in mind that this is a “dirty” fix as you will need to first setup up the sonoff.things file as well as the sonoff.items file. There after you just need to add the sonoff topic to the payload and the device will be added to the sonoff.things and sonoff.items files. As node red is part of the openhabian system I used that.
Hope it helps !
