As of an hour ago all my Samsung SmartThings Multipurpose Sensors are reporting the dreaded “This device is unavailable” status.
I initially thought it was just the one at the garage door (last reporting 89% battery) and tried to reset it and even uses a fresh battery. Now, it won’t even get discovered by the hub.
One of the “working” ones in the attic went offline as well as soon as I triggered an open.
Motion sensors and light triggers are working fine, so this is specific to the Multipurpose Sensors (version using CR2450 batteries).
I’ve power cycled the hub as well as the network connects, no luck.
Hopefully tomorrow’s firmware update fixes this, otherwise something else on the network is broken!
