On the web app, the Power Meter page offers the following timescales:
15 mins, Hour, Day, Week, Month
Those are all useful in their own way, but I would like to add 6 and 12 hour options. I think these would be helpful for certain types of power tracking and troubleshooting.
Related to this, I think it would also be helpful to have set time frames that aren’t dependent on the current time of day. For example, if there was a 6am to 6pm option, that would cover a typical day’s solar production window, and give you a nice clear visual of a day’s production and consumption. Currently the only way to approximate this is to use the day view to see a full 24 hr cycle.
I think another interesting timescale would be the entire solar production window for a day, based on when sense detects wattage coming from the PV system. So this custom solar timescale would vary in length depending on the time of year.
If you are worried about the interface becoming too cluttered with all of the time scale options, you could add a page in settings where the user can choose to display only the ones they want to see. I personally would turn off Month view, as I don’t find it too useful.
If you want to get really fancy about it, you could look at the timescales that people manually zoom to view in the app (assuming you collect that data), and use that data to inform which timescale options to add.
