My ST Multipurpose sensor shows as offline, however if I open the door it’s attached to it’ll immediately report as Open, same when it closes. I can poll it for temp and I get a current/accurate temp. This is the only device in my network experiencing issues at all. There are no 2.4Ghz wireless devices nearby, and no changes have been made to my network that would explain this device going offline.
I have 20 Zigbee devices (8 zwave) connected to my ST Hub. I’m fairly confident that my Zigbee network is pretty robust. There are 2 Zigbee devices in the same room as this ST sensor, and several within range, not to mention that this sensor in particular is likely in range of the ST hub directly.
