Comparison with Utility meter

[kevin1]

Hayward, welcome ! Here are a few thoughts and questions.

1. 14kWh is a lot. What is your house configuration ? Do you have solar w Sense Solar ? How much energy do your typically use in a day ? Are you sure you have your Sense on the house mains and not just a single sub panel (yes, that has happened several times on this forum) ?

2. Take a look at your Power Meter and Trends to see if there are any places that look like Sense has dropped data (total usage drops to zero). There was an issue with the Sense API and backend a few days ago, that did not drop data, but left some unprocessed. The fix has been percolating through everybody’s readings, but might not hav reached you yet.

3. Which utility do you use and how did you get access to the utility measurements ? Many utilities use smart-meters, but that doesn’t guarantee accuracy if you are looking at their measurements via their website. Some utilities only do “actual reads” every so often, even with a smart meter in place. In between they do “Calculated reads” which can be off by a large margin, especially over a days time without any more actual reads.

4. Do a more detailed comparison to find the problem area. This posting includes a bunch of ideas for easiest to hardest:

So You Just Installed Your Sense and You Want to See If It's Really Working

You just installed your Sense and you are raring to see it start detecting devices in your house. The first question that many users ask while waiting for that first detection is “How do I convince myself that the Sense numbers are accurate (or figure out that you have a cheating utility company) ?” This is a short primer on ways to double check the basic numbers coming out of your Sense. What can you do ? Just believe - Lots of other people have validated Sense’s accuracy in their particula…
