Basic app. Needs more controls

So this is a water heater but some more info would be appreciated. On the main panel of the unit in the garage you can easily see what the max temperature is set to and what the current temperature of the water leaving the unit is. The app you can only see what the max temp is set too.
Having controls of the schedules and peak/off peak would be great. Especially for rentals and remote homes.
Reporting is basic. Would love to see max and average temperature over selected times. Like max/average by selected hour. Or max and average by selected day
Also total power utilization by hour/day/week/month/year as well as selected periods.

Ability to export to iPhone function to pdf/Email/text would be great.

Notification integration for alerting/alarm so app can tell us right away if there is an issue would be truly useful.

Automatic notification in app of any alerts/alarms actions would be good.

App is too basic

No real-time data, so more info is available right on the unit monitor it is a shame not to have that in the app
