I wonder if it’s related to this

Z-Wave storms - looks like HE Hub's fault?

Ok Zniffer trace and hub log output below. It's the hub that is spamming with loads of Basic Get commands and the log just shows the responses to the Get. I've been chasing phantom nodes and buying $100 of debugging equipment by now. Doesn't this look like HE is the culprit? What am I missing? I have turned off scenes and groups. This is just a RuleMachine 4.0 turning on a fan, triggered by a doubleclick of a switch. [hubitat] [zniff]
