2 stars is generous, gave as it has potential to be great but my guess is the ROI isn't worth it to Google History lags 1+days behind, data that should be available such as outdoor temp, humidity, etc. isn't included, doesn't always record data properly (ran 5h, shows 2h), data not available real time via app so you can see usage for day (servers update 1x a day), must email to get history and depending on request takes a long time (week or more), drops wireless connection often, and more.
