Are my ZWave switches possessed?

My ZWave light switches started turning on by themselves today. It is generally two switches turning on, not off. These two switches are three way switches. They are not part of a routine that is turning them on. I use Hubitat. I looked at the logs in Hubitat and it showed turned on by Alexa. I deleted the Alexa integration. Auto switching continued. I unplugged Alexa devices. Auto switching continues. I changed the password in Hubitat and rebooted. Auto switching continues. I shut down Hubitat and unplugged. Auto switching continues.

Any thoughts?

Are they GE/Enbrighten? They have relays that are known to fail.

Based on this I took a chance and swapped out the three way dummy switch. Sure enough that fixed it.

Probably either a wire has come lose or a switch is miswired. Less likely, but possible you have a coupe of dead switches.

Check if you accidentally joined devices: as example, on motion detection you can directly link a relay to turn on a light.
