I came home from work a few days ago and both of my WDC-20's were "off", meaning the screens were blank and the house was cold. I pulled them both off, replaced the batteries, stuck them back on the wall and everything seemed fine except Vera lost them both. I wasn't surprised by this nearly as much as having both of them go the same day. I spent an hour tonight trying to exclude/include them, reading the directions, searching this forum and I'm not able to get Vera to recognize either of them.
I'm willing to accept that they could be dead but before I pull out my pistol and put them totally out of their misery (and mine) and buying a couple Trains I wanted to make sure I'm not missing something.
