I have tried and couldn't get them to pair in anyway, Abode Tech said they will not work. Bunner I have about 10 sets. Iris don't redem those.
I just double checked a couple V2 contacts to see if anything changed with the update that was done last week. They still pair as a temp sensor. You need to do a factory reset and hold pin down as you insert battery and hold for a couple seconds more. They take a minute or two to pair. I replaced my door contacts to all Abode brand as I wanted my security end to be all Abode devices. I'm a lot more open to HA devices being from different makers and communication protocols. You can always sell any of your old devices on eBay if you want to recoup back a few more dollars.
