OK, the GE switch by default uses a zwave device handler type that has a problem where it treats every time it is polled as a physical on event from the switch even though the switch doesn’t turn on. This throws off anything which is “following” that switch and it’s a pain in the neck.
Fortunately, there’s a really easy fix, which is just to change the device type handler for that device to a different One that doesn’t have this issue.
Support can do this for you or if you are comfortable in the IDE you can do it for yourself. This is just a software assignment, you could switch it back anytime you wanted.
@sbdobrescu could say more, I believe he’s the first one who reported it in the forums.
