So I've running ST for a couple years and now all of a sudden I have multiple switches, lights, contact sensors are going offline for no reason. Got 2 GE switches next to each other and 1 is off line, 3 Visonic contact sensorsbfeet from each other and 1 goes offline and back constantly either new batteries. My Schlage lock work about 50% of the time. Single story house hub almost in the middle of the house. Not running g any webcore or anything special pretty much a plug and play set up system. And one of the presence sensors works but its not logging any activity. Using Classic App 90% of the time but new app shows same indicators. Did the ZWave repair several times and changed the Zigbee insecure to see if that helped and nada. You guys got any suggestions other than reinstall everything?
