Dome window sensors

I have 3 dome window sensors that worked while connected to wink hub. I disconnected them from wink correctly but only 1 will pair to the hub (the ine above the hub). The other 2 on the furthest part of the house will not connect. I even put a zwave repeater in the room next to them but they still do not connect. Any ideas?

Did you exclude them yet? (With wink or ST). Have you run a zwave repair in SmartThings?

I have several of these and they drop out fairly regularly. try pairing it near the hub.
