This looks like something is fundamentally wrong. Saw in previous posts you switched to openHAB Milestone 4.1, right?
I did this too and installed binding from Marketplace. Got the same errors!
Problem is within the Milestone version: Whyever Marketplace took the 3.4 bundle which simply doesn’t fit. Using Marketplace for 3.4 and 4.0 are working correct.
So if you’re running openHAB 4.1M1 you need to downlad the 4.1 smapshot bundle from Mercedes Me and drop it into addons folder
