Really 2.2.0? You decided to update and choose a release that is well over a year old? Or is this a typo?
The rest seems to point to you’ve installed OH 2.5 M1.
Try Clear the Cache first. You should be seeing entries in openhab.log too. This problem needs to be solved first.
Choosing the 1.x binding is appropriate for now but eventually you will want to upgrade to the 2.x version. Both versions can run in parallel but they work fundamentally different so it’s not just a simple copy and paste of configs to upgrade.
