Working great for me. Useful as is.
Battery level is also shown.
I was thinking that the Point reports temperature, sound, and humidity. The temperature looks, by eye, a bit over reported. Maybe in the future, it would be cool to have a table with the values read and the time-of-day.
Would be nice to format the date/time according to Windowa locale (mine is dd/mm/yy & 24-hour clock).
The ads are tastefully done. Good on ya.
On the 24-hour chart, it would be nice to have all 24 hours marked and without the date.
On the7-day chart, it would be nice to have each day marked (Mon, Tue, ..., Sun). Of course, you would need to find the start day of the week from the Windows locale. When I am from, the start of the week is Monday.
Great job. I will use it regularly as is, but am looking forward to future enhancements.
