Ratings and reviews

The app is buggy and needs fixed. The "month" button shuts down the app for some reason. I had successfully used the month button previously. We have had the system in for 6-8 weeks, so I'm not sure what could have happened since there is no update. Otherwise it seems to provide good information. We have compared it to our meter readings and they track.

Great app and measuring devices. I haven't had any stability issues. It is missing a much needed feature. Most billing does not start at the beginning of the month and end at the end of the month. Please add a feature to change the start and end date for the billing cycle. It is possible to to use custom dates to view usage but it does not provide a total for the custom date range. Also, you have set the dates each time you go into that section. Keep up the good work. Add the feature, 5 stars.

Worked fine for me, paired my device pretty easily, got an error about the CTs being the wrong direction even though they weren't, but I hit try again, and that seemed to do it. App worked fine, able to read energy in real time without freezing.
