Normally, this is what you will see if the binding is not running - is the controller online? If not, what is the state? Are you sure the binding is running (I know you said it is, but, just checking… )?
looking at the openhab.log is see this error:

I’m not 100% sure as it’s not been discussed yet in the maintainers discussions, but over the past couple of years, there have been 2 releases per year - one in December, and one around June. So, I would guess December…
You don’t necessarily need to move to the snapshot if you don’t like the idea of this - you can also use the milestone builds which are updated periodically (about every month) and M4 was released very recently. I’m not sure if you need a very recent version of the binding or not (ie if we’ve made any database updates that you need in the past week or so) - if not, M4 might be a good option for you.
