Devices keep losing connection.

I have a Vera3. So far I have 3 wall dimmers installed, all on the same floor in my house (first). The Vera is located in my basement. I have a 3-way GE dimmer in my dining room. I have a Linear WD500-Z dimmer in a closet near my front door. I also have an Intermatic dimmer in my family room.

The GE dimmer works fine (although I have no scenes set up for it.)

The other 2 do not work; for now I am focused on the Linear. I have had it working (working = responding to commands and one of 2 scenes I set up for it) but then it just fails. Details: one scene I had it set up for was to come on at sunset. It did this perfectly yesterday and I could even dim the attached lights from my phone after the scene ran. Later in the evening another scene was set to shut the lights off. This scene failed as did an attempt to dim the lights a couple of hours before the scene-configured shut off time.

At this point the system isn’t even detecting the switch at all and I am at a loss for what to do next.

Any guidance will be appreciated.

Happy New Year to all!
