Hi, Will Zigbee 3.0 works on ST Version 2 hub ?
In short, yes…however there may be some zigbee 3.0 protocols that may not. Someone with more knowledge of this will hopefully chime in
Touchlink commissioning and Zigbee green power devices like the Hue Tap don’t work with any ST hub at the present time, but both are optional features under the 3.0 standard.
I don’t know the rest of the details.
I have successfully used several Zigbee 3.0 devices on my v2 ST hub.
(I’ve since moved those devices to an alternate brand of hub).
