I have been using SmartThings since 2015, and am seeing something completely new. Smartthings can see all of the devices in my home (>200), but suddenly it can’t control about 30 of them. This applies to some Z wave switches, Zigbee switches, and even Philips Hue lights. If I turn the switches on and off manually, or control the Philips Hue lights with the Philips app, Smartthings immediately shows the correct status. So it is properly reporting device status. However, if I try to control the device, nothing happens. It doesn’t matter if it is Zigbee or Zwave, the device does not respond. I have rebooted all of the hubs and routers. Also, I have exactly the same behavior whether the control comes from my phone app or from WebCore. About 30 devices no longer respond, but I can see the status just fine. However, most of the house is humming along just fine.
The problem began a week ago, about the same time as a hub update.
Haw anyone else seen this problem of multiple devices suddenly refractory to control, but all of which are clearly reporting their status back to SmartThings?
