This question is about a Z-wave wink contact sensor with a SmartThings v3 hub. Now first off, I’ve already ordered a different sensor, but I’m trying to understand why this sensor dropped offline all the time.

It’s in the basement. I have many other zwave & zigbee sensors in the basement & 1 may drop off in a rare occasion - but that’s it. For this Wink sensor, as soon as I replaced the battery or removed it & stuck it back - it came right back online. It lasted for a few hours & then permanently off line until I did the battery thing.

This is more about trying to learn & understand what possibly could be going on here for future reference opposed to making this particular sensor work. Things I did:

1. Reboot hub.
2. Replace battery with new (old was 77%)
3. “Rebuild” zwave network. Whatever that does(I think nothing)
4. Delete the sensor in zwave exclusion & add it back again.
5. Get a zwave smart plug that acts as a zwave repeater about 15’ from the sensor.
6. Tried another driver. One was “switch” & one “sensor”

Does a zwave actually mesh an an “extender” do anything? For this is did nothing. I dunno if that is marketing or can actually make a difference. I have 3 other Wink contact sensors that rarely go offline & if they do; they get back on shortly in their own. They are in the same floor as the hub.

Anyone have any clue what could be going on here?
