I have about a dozen Zooz z26 switches, four Innovelli fan/light controllers, eight Schlage Connect locks… All working flawlessly with Alexa thru my v3 SmartThings hub for over six months.
Yesterday I added three new devices to the network (another Zooz z26 and two Meross outdoor outlets – all for Christmas lights). In doing this, I needed to turn off the circuit breaker that powered my ST hub (same circuit as the new switch).
When I brought power back up, all three devices were connected to the Hub and work fine with the ST app. However, now I can’t voice control ANY zwave devices at all. Voice control for the few WiFi devices I have works fine. Voice control for zwave (thru ST hub) does not work.
