I bought Z-Wave daughter cards on EBay and managed to configure my Baldwin Keyless locks. You can buy the locks with or without the daughter cards already built-in.
What I did:
- Move my Hubitat pretty close to the locks (~5-6 ft). Took a long ethernet cable (and extension cord).
- Installed the daughter cards (drop-in installation).
- Launched "Discover Devices" on a web client connected to my Hubitat's internal web server. This is accessible on the mobile app as "Connect to Hub".
- Clicked "ZWave"
- Started the Z-Wave exclusion process.
- Pressed the "Z-Wave Ready" button on the lock itself - this is the left button of the two buttons near the top of the reference card. Before you install the Z-Wave daughter card this button does nothing, but once the card is installed it causes an amber light to display through the reference card on the back of your lock.
- Confirmed that "Unknown Z-Wave Device Excluded" displayed on my phone.
- Started the Z-Wave inclusion process
- Pressed and HELD the same button on the lock.
- Stopped when "Z-Wave Device Found" displayed on my phone - it will be a Generic Z-Wave Lock.
Through this pairing I was able to add codes, lock/unlock, etc. Everything I wanted. I'm hoping to be able to get battery low notifications as well, though we'll see. I was also able to move the Hubitat back much farther from the locks and the connection still worked - I think you do need to be fairly close for this pairing as it wasn't working earlier when I tried it with some distance.
Good luck! Just didn't want to leave this thread hanging since I have actually made this work.
