Incorrect Lock Status

I have a U-Bolt Pro Series, Z-Wave lock, and an Z-Wave Contact Sensor on the back door of my garage. Both are controlled by a Hubitat Elevation Model C-7. I have a Z-Wave automation that will lock the door if the Contact Sensor indicates the door status has been changed to CLOSED. I have another automation that notifies me if the door has been left OPEN, or UNLOCKED.

There have been several instances when was away from home when the Hubitat indicates my lock is UNLOCKED, and the door is closed. This can be very alarming! I’ve always thought it was a problem with my coding automation. However, it happened while I was home. The Hubitat Status indicated the door was CLOSED, but lock was UNLOCKED. I can only assume that this is what had occurred numerous times as well.

Upon investigation, I could see the door was physically LOCKED and the U-Tec app indicated the door was LOCKED. So my Hubitat and U-Tec logs showed a different status. When I compared the Hubitat Log, to the U-Tec app log. I tried to put together the sequence of events.

  1. The U-Tec log indicates the lock was last UNLOCKED with an authorized fingerprint.
  2. The Hubitat Log indicates an automation Command called to LOCK the door.
  3. The U-Tec log indicates then Z-WAVE LOCKED.
  4. The Hubitat did not receive any indication that the lock actually LOCKED.
  5. A few hours later, when I recognized the issue, I manually UNLOCKED the door.
    This is shown in the U-Tec Log as Manually UNLOCKED.
  6. There is no indication in the Hubitat Log that the door has been UNLOCKED, but my automation, (likely triggered by the contact sensor closing), initiated a Command to LOCK the door.

At this point both the Hubitat and the U-Tec statuses were synchronized. Likely because the error repeated itself again and toggled the U-Tec status without toggling the Hubitat.

I believe that in both there were two cases where the lock failed.
a) When the lock was UNLOCKED with a fingerprint, the lock did not communitcate to Hubitat that the status that the door actually UNLOCKED, and

b) when the door was Manually UNLOCKED (from inside the garage), the lock did not communicate to Hubitat that the door was actually UNLOCKED.

It seems the fix is easy, just Manually UNLOCK the lock which seems to repeat and resynch’s the door status. But it is very alarming when I am away from the home and cannot manually LOCK/UNLOCK the lock to resynch it.

I remember seeing another post recently about a similar instance where the user had to manually LOCK or UNLOCK the lock to re-synch.

Any help you can provide would be great.
Thanks,

I ordered the same lock as I have a Hubitat as well but it has not arrived yet. I have a C-8 Pro but that shouldn’t make any difference. I have found the connectivity is limited at this point but I’m hopeful someone will release a custom driver that would open up the capabilities using rules in Hubitat. I assume you are using the Generic Z-Wake lock as the type?
I’ll let you know when I get mine if I can get it to work with Hubitat.
