Linear/GoControl Light Switch (WS15Z-1) wrong status

I have a Z-Wave Linear light switch (WS15Z-1).
I’m using the default Z-Wave Switch device type.
I can turn it on/off fine, but in the app the status always shows as off.
Anybody know how to tweak the Device Handler groovy code in order to fix this?
Or anybody has a Device Handler that works with this model?
I have searched the web and the github repo without success.

Mobile App version: 2.1.5
Hardware: hub v2, US customer Rev E
Firmware: 000.014.00040

Have you figured it out? I have a handful of Linear switches that stopped working over the last couple of weeks. They work normally with triggered physically, but I can no longer turn them on/off from the mobile app or any smart app.

My other light switches from GE and Leviton still work just fine,

No, I haven’t been able to resolve the issue. The switch works. I can turn it on/off from the mobile app, the problems is that the app doesn’t show the actual state of the light which is incredibly annoying since that means I can’t do it remotely because I don’t know if I’m turning the light on or off.

I see. My current problem is different then.

Now that I think about it, I did have the same problem as you have with some switches I no longer use. Read that thread:

Hi @pakmans
Do the outlets works now? I’m about to buy this model and wonder if it works correctly with ST.

I never got it to work. I haven’t tried any further. I just use it as a repeater.
