Generally about 20 feet - but I’ve also tried it within 1 foot.
Curisouly, I’ve got this response from Monoproce:
Thank you for contacting Monoprice.
Upon checking, this item is compatible with Z-wave hub, and we didn’t test it yet with Samsung V2 Hub.
If you want, since your item is still in warranty for refund. I can send refund request instead of replacement.
I do apologize for the inconvenience.
OK, work with @RBoy and hopefully he will be able to help you

Do you have other device handlers in your account? If you’re running into the stale DTH issue, any unused device handler can be blocking it. Just to ensure that it isn’t the stale DTH issue : FAQ: My lock/device does not pair or appears to pair but it won't show up in the mobile app or IDE, remove all device handlers (or republish ALL device handlers one by one), then try to reset, exclude and pair it again within 5ft of the hub.
If it works then it was a stale DTH, now install the custom DTH and either switch the DTH or pair it again.
Another way to check if you’re running into the stale DTH issue, open the IDE -> My hubs -> Click on List Events, there you’ll see it pair successfully in the list of events. If you don’t see a device being paired after the pairing starts (you’ll have to refresh the page), then it’s a bad sensor.
If that still doesn’t work then you may have a bad batch of sensors. It happens sometimes, a few folks have reported it and usually RMA’ing it and getting a replacement solves the issue.
I’ll ask Monoprice for replacements. I’m not too enthusiastic about paying another $70 for shipping.

These events are unrelated (they are UPnP events). Basically your device isn’t pairing itself which is for one of 3 reasons:
It needs to be excluded (can be easily done and when it excludes you’ll see an event in the same place showing that it was excluded). If it doesn’t exclude then you’ve got a bad device.
It’s having trouble communicating (easy to fix, bring it closer and reboot the hub)
Batteries are dead
If it’s neither of the above then it’s a bad batch and you should have Monoprice send you replacements.
