unfortunately your binding is not working with openhab 4 anymore. A user compiled it so it worked with 4.0 but now with 4.2 it's broken.
Possible Solution
I could try to create a new binding based on your code, but only if you're ok with that (I guess you're not into openhab anymore? ...which is a pity because it has developed incredibly )
