Is this binding available in the snapshot yet? I saw it was merged but not available on paper UI There is nothing in the add-ons docs either I got my hand on a bargain Grohe sense and after downloading the jar binding I was able to create the bridge thing but the sense thing created errors when I added it and it remains uninitialized.

Errors:

@vzorglub What exactly do you mean with "downgraded" the binding (from https://github.com/openhab/openhab2-addons/pull/3696#issuecomment-419699637). I've never tested the SENSE device, at I don't have such device in the account I used to develop this binding with, so it could be, that the device model for the SENSE is completely different from what it is for the SENSE Guard.

Closing as I can't reproduce the issue. Please re-open if it occurs again or open a new issue :)
