Hi,
I originally reported a Z-WaveJS bug related to the Kwikset Home Connect 620 deadbolt locking mechanism more than a year ago (around April 2025).
Please see the old thread for background and details. “[C-8 Pro/2.4.1.xxx] Kwikset z-wave deadbolt randomly unlocked by itself, potentially after switching to use Z-Wave JS”
The issue now appears to have resurfaced after recent Hubitat software updates.
@aaiyar — since you were able to reproduce the issue previously, could you help confirm whether the problem exists if you still have the Kwikset Home Connect 620 deadbolt available for testing?
My current Hubitat configuration:
- Hardware: C-8 Pro
- Hub firmware: 2.5.0.135
- Mobile app version: 2.1.3.92 (432) on Samsung Android phone
I performed additional testing and found that the issue only occurs when using the Kwikset 1-touch locking button on the exterior keypad. Other locking methods/scenarios appear to work correctly.
I’m attaching a few pictures below for reference.
Thanks.
