- smartthings hub v2
- GoControl Z-Wave Isolated Contact Fixture Module - FS20Z-1
- wired in parallel with linear actuator to raise/lower a downdraft vent
A few days ago at 12:30am I woke up to hearing my telescoping vent for my stove top constantly actuating up and down. I have a zwave relay connected to the vent that is configured as a momentary switch. When the switch is pressed, it raises or lowers the vent, depending on the current position. Somehow, without any action by me, my smarthub decided to force the switch into a constant “on” state. The hub completely ignored my commands until I performed a reset.
First of all, how could this have possibly happened? I don’t see any way in which a momentary switch would be forced into an “on” state unless the hub just completely lost its marbles. Second, why did the hub refuse to respond to my commands?
Here is what the log reported -

3 days ago DEVICE /physical switch on Range Fan switch is on
2016-06-08 6:16:54.352 PM CDT
4 days ago DEVICE /digital switch off Range Fan switch is off
Notice that is says the switch was physically actuated. But how could that have happened without me touching it? Does that mean the internal relay stuck on randomly? I am not convinced that is the case however, because I did not command it to do so, and my hub locked up and didn’t respond to my commands when I tried to reset it.
I would also be interesting in learning if anyone that has the GoControl Z-Wave relay has had them randomly fail into an “on” state.
Any help is appreciated.
