Sometime in the last couple of days my four Samsung multisensors and Ecolink motion detector have become unavailable. My LifX lights and Arlo Netgear cameras are still functional through the SmartThings hub. There was a notification re. an urgent (no prior notification) update to the firmware on the hub on May 3. I’ve rebooted the hub a couple of times to no avail. Am I the only one having a problem?
