Yes, you can scrape the Sense web app for higher resolution data with a few caveats. I did it a while back.
The caveats:
- The Power Meter only gives up relative data for both time and power, plus scales for x and y relative data so you need to do your own transformations back to seconds and watts.
- New development of the current web app has ended, and it is on life support, so there is some risk if you want to rely on it for critical data. I don’t think the risk is high, because Sense seems to want to keep it around for a couple of critical features not found in the new app infrastructure - Data Export and the informal API that powers the Home Assistant.
If you have any familiarity with python coding, the real-time calls in the API might be better for you, though you will need to maintain your own database.
