With the update of the ESH stable build yesterday, I’m now going to update the Z-Wave binding use a new feature that’s been added to improve the way entries are added to the discovery inbox. I hope that this will solve the issues where people have been having unknown devices discovered (obviously it won’t fix unknown devices that aren’t in the database! ;)).
You MUST update OH2 to use this. Any new versions of the Z-Wave binding after today will require an update to an OH2 build from today or newer.
