I have 3 working fine. They are rather finicky and sometimes loose pairing after hooking up new wired sensors such as light switches or garage door opener. I think that is because these are acting as repeaters and the lock starts talking through these confusing the aħ. Either a reboot it re-enrollment fixes this. In fact they have become more reliable as I added these other devices. Make sure they are not already enrolled , try removing first. Other than that were did u get them as there are a bunch for sale on ebay without the zwave module?
