I’ve followed the 5-step (ish) way here: My Danalock v3 Z-Wave Configuration 5. Step Solution
And that worked perfectly.
Used the Z-wave integration in the UI, added the lock secure, and sent the JSON via the service call.
I did notice that I had to make extra sure that there were good enough connection, I had the AEOTEC stick inside the rack, and had to place it on the outside to have a reliable connection.
