I am a new Hubitat owner and I am just starting the process of moving my devices from SmartThings. Most of my Zwave devices are Zooz switches. I ran into an issue with SmartThings and these Zooz switches where the switch would freeze and would not work until power was removed (eg, pulling air gap or flipping breaker). Zooz support couldn't figure out the issue but it seemed to start happened around the time the SmartThings Classic app was decommissioned, me updating firmware, and adding the switches with S2 security.
If S2 is wreaking havoc on these Zooz switches, is it acceptable to install them with S0 security?
