I have a scene in the mobile app that the status constantly flips between zero and 5% every couple of seconds.  It does not turn on any lights in the scene, only showing on the app, but it seems to me this may be an indication of a problem.  Perhaps with one of the devices in the scene?  I have disabled a few devices to see if it helps, but so far no success.

Do any of the devices in the scene also change status? 

Try disabling the calculations for all devices in UDM then add back one at a time. This only affects UD Mobile's calculation, has no effect to eisy. 

how do I do that?

Oh my, you are correect , one device is changing status.  I guess that means its going bad?

What kind of device (model number) is it, and how old is it? Some types are more known for issues than others.

Might help explain it. Not sure if options have changed since I know UD Mobile UI has changed slightly over time.

Lamplinc dimmer, pulled it out problem stopped, I will try replacing later today as I have others...this one is probably pretty old.  Thanks much
