ZEN15 false readings

The ZEN15 works very well controlling and monitoring the in-ground outdoor sump pump I had installed. See photo of the backyard flooding caused by irresponsible land owner and county subdivision planners. One strange thing though. On the SmartThings app, the ZEN15 shows a status report with historical charts of past usage (see photo). Each bar should indicate watts of power used, but mouseover shows the values to be zero. Why do I see changing bar heights, but zero values for each?
(Photos will not upload. Just photos from my iPhone. Pretty standard stuff. This should work but does not.) see hpoc.org for photos)

This sounds like a SmartThings display issue. I’d recommend sending these screenshot to both our support and ST support for review so we can see where the issue is rooted.
