Cheap/bulk Water/Leak Sensors?

TL/DR: If these fall off the mesh, they might stop regularly reporting battery until you reset/pair them, remove them, and then re-pair them from scratch.


I recently did a Hub Protect migrate from one C-7 to another. That kept my Z-wave network intact (except for one hiccup), but it meant I needed to reconnect my 120 Zigbee devices, basically by resetting each in turn while doing a Zigbee pairing. That mostly went smoothly except for two classes of devices: a huge issue with the Sylvania/LEDVANCE strips and these Linkind water sensors.

Although the issue with the Linkind water sensor was minor. A reset (holding the button on the back for 5 seconds) let them immediately pair with the new hub. However, they no longer reported battery at all, so they started going off in my Device Activity Check daily report. They still worked; making them wet (touching metal to the contacts) caused them to alarm, both locally and to raise it to Hubitat. They just weren't making regular battery reports anymore.

I specifically removed them from the hub and then paired them again from scratch (without the device pre-existing). That let the battery updates start up again. It just meant I needed to re-add the device to all the apps they were in before I removed them.


This issue is minor and easily corrected, and not likely to occur to many people. I still think these are a bargain.
