After about a month of owning an ST v2 hub I’ve come to the conclusion that Z-Wave is useless compared to Zigbee.
I’ve tried two different contact sensors (one was a GE, can’t remember the other) and an Aeon MultiSensor 6. As long as these devices are in the room with the hub they work. Go right outside the room and its about 50/50. Beyond that and there’s zero chance they work. This is with three of the Iris Smart Plug Zigbee/Z-Wave repeaters, which as far as I can tell only actually repeat Zigbee (which they do a great job of, btw).
I’ve tried numerous Z-Wave network rebuilds (after unplugging hub for 15 mins w/no batteries), device exclusions/inclusions, device replaces, etc. but I just can’t get any range to speak of out of the Z-Wave devices I’ve tried.
Yet I have 10 Zigbee contact sensors throughout the house and only one location needed a repeater (the Iris Smart plug) for two sensors at that location. All of them work instantly or near instantly every time and I have yet to have any fall off the network or give any false open/closes. Makes no sense to me since Zigbee is on the same frequency as Wi-Fi and I have 3 APs throughout the house and numerous 2.4ghz devices yet Zigbee works so well and Z-Wave doesn’t.
Is there any thing else I can try? If i could find more advanced sensors like the Aeon and door locks that use Zigbee I wouldn’t care much but I do want to use these devices and Zigbee seems to be limited to switches and contact sensors.
