Utility Bill Comparison to Dashboard #348

Open aesculus opened 1 year ago

aesculus commented 1 year ago

Well after running the system for a month I just compared it to my utility bill. It was spot on. Maybe less than 1/2% off on some power figures but certainly well within tight tolerances.

This tool is going to be very valuable in monitoring and tuning optimal Powerwall and energy use.

What a great tool and thank you for putting this together.

Hi @aesculus, I appreciate you taking the time to share your positive experience with the project and the measurement observation. Your kind words are a great source of motivation for all the dashboard contributors. Thank you! 🙏

It's not even close to my utility bill that just came in today ... ;-)

LOL (not really!) this is because Xcel is buffoons and despite PTO in late August, their billing department hasn't "caught up" yet ... it "takes a while" to "enable solar" on my account. Over a month - WTF?!?

In case my sarcasm isn't obvious, GREAT job @jasonacox (and others) for your fine work on a really nice tool.

Keep an eye on it! We had a similar thing after our PTO. The bill didn't change. Our utility company said it could take a month or two. I check in with them after a month when it wasn't fixed and found out the "change" didn't go through so they had to do it again. A few months later and it was fixed. It's a bit ridiculous, but in the end, they recomputed all the months to did the necessary adjustments.
