Let us know how it goes and if that fixes the extra From Grid usage. I’m especially interested in what a the Day solar summary looks like the subsequent day. Please post a screenshot of the summary for “Yesterday” once you have a summary for a full day of solar operation.
I can tell you that the monitor is already more accurate. The devices are now popping up more consistently.
I will post again tomorrow night with a screen shot of the full solar production.
Thanks ! looking good.
Right now To Grid - From Grid = Net production, as expected. I’m interested in the same display for Aug 8th, but from tomorrow, after Sense has converted / closed the data to Yesterday.
I’ll post the totals for today, tomorrow.
Let’s hope everything adds up!
Thanks. To Grid - From Grid = -13.3 while Net production is -9.8. I think this is a different variant of the issue you saw at the start of this topic (spurious extra load being added to From Grid), but I think it’s a relatively new issue with the solar summary that affects all solar users. I’m still investigating.
ps: The anti-corrosion extension cables do fix a real issue that Sense support can detect from your data, so you did the right thing to install.
Bug is confirmed and in the Sense system. No ETA for a fix yet. Basically the 1AM update of the Solar summary corrupts (adds extra kWh) to the From Grid of the previous day. Same goes for Week/Month/Billing Period summaries. Incomplete Days/Weeks/Months/Billing are correct (To Grid - From Grid = Net production), but summaries for completed Days/Weeks/Months/Billing have discrepancies. The From Grid is to blame !
Thanks for getting to the bottom of this.
Now wait for a solution
Kevin: Thanks for your efforts! Now let’s hope they get the fix in ASAP!
Here’s one where the issue is almost as obvious as your first example.
Here, my From Grid is the same as my whole house usage for the day.
I think what happens is that Sense slips in an extra chunk of From Grid data from the 12AM-1AM period of the subsequent day. In this case that included EV charging !
I just received this message from Sense support, then did a little spot testing myself. it looks like this issue has been fixed and the summaries have been backfilled at least some period of time into the past !
Example: Net Production once again equals To Grid - From Grid (within 0.1kW rounding error)
I am seeing Weekly and Monthly summaries show a difference of slightly greater than 0.1kW between Net Production and To Grid - From Grid, but my guess is that might stem from multiple roundings as the issue.
Fantastic! Thanks for your efforts!
