Open / Close Sensor stuck on open

Drats - just had this issue twice. Hopefully it’s not a manufacturing issue.

Have removed some batteries - those in multi sensor is too darn difficult to remove. Unplugged hub and going to wait for min 15 mins. Hope I’ll see improvement tomorrow.

In order to get the neighbour tables to rebuild, it is important that the subsidiary devices like the sensors remain powered on while the coordinator, in this case the SmartThings hub, is off power for at least 15 minutes.

the idea is to get the end devices to go into “panic mode” which will cause them to then rebuild their address tables once the Coordinator comes back online. If you have everything off power at the same time, the tables will not get rebuilt. It is the sensor’s inability to contact the hub that prepares it to rebuild its neighbour tables.

FAQ: My Sensor (any brand) is Stuck on Closed (or Open)

When any sensor gets “stuck” in one reporting state, open or closed, it’s almost always one of the following: Low battery. once the battery gets down to about 30%, the signal strength drops by a lot. It just may not be able to report. So you may want to try just changing the battery if it’s getting low. sometimes a new device gets delivered with a bad battery, it can happen. orphaned nodes. Zigbee does have a vulnerability to this. The fix is to unplug the hub for at least 15 minutes, including removing the batteries. This will cause all the zigbee devices to realize they’ve lost connection to the network, and then when you plug the hub back in the address tables will get rebuilt. You may not see an improvement until the next day, it can take a while for the changes to propagate…
