So I take it that WWN doesn't include their Protect devices. I upgraded to UI7 this morning and noticed the loss of Watou's plugin for the stat but sure enough the Protects are still intact - albeit I have no idea if they still work.
I added a protect gen 2 today to vera edge, looks like working
it created two device automatically 'WWN Smoke - roomname' and 'WWN CO - roomname'
only issue I noticed so far when setting up alerts was that both devices say "is armed and detects smoke", "is armed and stops detecting smoke", assuming that is a typo for the CO device and it should say 'CO' rather then 'smoke'
that said I have not tested the actual device with smoke or co to set off the alarm, but they look like working to me
