Switch going on/off

I have a ceiling fan on a Z-wave switch. Not a Z-wave plus switch. The only place I have that switch being used is in Dashboards. And I use the Z-wave poller app to poll this and a couple other non-plus devices.

Recently the fan just started coming on by itself. I checked the events for the fan and it shows it going on/off quite often. Most of the time the on time is just a second or 2 which is why I never noticed it. The fan doesn't actually get going.

But a couple times the fan has actually come on and stayed on.

Any ideas what to look for? Could the polling be causing this?

I doubt the poller could be triggering it, but one never really knows. Does the In Use By section (on Device details) show the fan in use by anything other than Dashboards? Is the switch in use by the Maker API? If it is, maybe there is an external app triggering it? What about Alexa/GH?

I have to go through this all the time when I have strange behavior in a device because I have so many sources touching my devices. Makes troubleshooting a nightmare, but luckily, I love troubleshooting things. :slight_smile:

That's the first thing I looked at. To see if I had it in use by something else. Nothing there but the dashboards and the poller.

Ordered a new switch, plus style. I'll change it out. Could be the switch itself.

Absolutely possibility. This is what I see for events in my only Z-Wave fan switch. If I trigger it manually, it shows physical as opposed to digital. Does your switch do this?

Yep, it shows physical. Didn't think of that. Been wanting to change all my non-plus's to plus's anyway. Guess this is a good start.

Is this a GE non-plus switch?
If so, a known issue (on HE, no issue on ST) and something myself and others suffer from.
So-called ghost events.
There are a few topics in this forum on it with no solution to the issue itself except to replace it.

If I had it to do over again I would skip z-wave plus and go straight to zigbee. Just my 2c.

Didn't know if it was a GE or not till I removed it. And yes it was a GE non-plus switch. I had 4 of these. I replaced them all. The problem just gave me an excuse to do so...

One thing I noticed after replacing the switches. I did a Z-Wave repair. Before I replaced them the repair took about an hour. After the replacement it only took about 5 minutes. A whole lot faster.
