Have been using the older app for 3 years now, but it’s now being retired and replaced by this one. Unfortunately, this provides less info than the old one, as I cannot see a table of data here at all only graphical.Other suggestions for enhancement:1. Would be very helpful if the app provided something like a year-over-year comparison of, for example, month to date or year to date performance.2. There’s also no panel level data presented, so with 32 panels installed, I have no idea how any of them are performing in comparison to each other, or to how they performed a year ago. This would be good to know if as a homeowner I notice a drop in the overall system performance. It might also have avoided an issue I experienced after my initial system install where several panels produced absolutely NO power for months, and neither Sunpower nor my Sunpower installer proactively noticed it! It was only after I submitted a ticket inquiring on the consistently lower than expected system output that someone finally took an action to address it.

INITIAL REVIEW: I was pretty excited about being able to track my usage, but I was quite disappointed. I have no confidence in the accuracy of its reporting. Yesterday, for example, it showed us producing 0.1 kW. (A cloudy, rainy day, so this is no surprise.). It showed home usage of 1.4kW. So, naturally, you would expect the readings to show 1.3kW being pulled from the grid. Instead, the app happily showed us feeding 1.5 kW *into* the grid. So, the app was 2.8kW off on reporting 0.1kW production. (This was so startlingly inaccurate that I even took a photo of it, just to make sure I was remembering this correctly.) Unfortunately, it was not the only time yesterday that the readings were off. UPDATE: I contacted Sunpower, and the app is reporting readings that make much more sense. There is still a problem of the occasional crash, but this is working MUCH better, and I am adding two more stars. Thanks, guys! NEW UPDATE, October 2021 Well… the numbers are consistent now. No strange math. However, the production and consumption numbers are still way, way, off. I downloaded Smartmeter to see what my meter readings were, and compared them with what MySunPower was telling me, and they have never matched, ever. According to Smartmeter(the local utility’s meter-reading app), for the last few months I have a 310 KwH surplus. According to MySunPower, I have a 2,500 KwH surplus. This is not a trivial difference!

The fundamental issue I have with this app is the fact that it would often fail when it was needed the most. Let me expand. In the San Jose area we had numerous big storms and some of which resulted in electrical outages (PGE) and some were hours long. We would monitor the weather and wind forecasts and when we thought there was a good chance of an outage we would attempt to change the battery settings from “self supply” to “reserve” and the app would fail. Note, we still had power and still had internet service at those times but for some strange reason the app wasn’t working so we couldn’t make that change. And worse yet, during several of those storms (and we had many storms this season) I would find the app wasn’t working or updating our data. I would have to go outside to visually look at our batteries charging status to know if the system was running correctly. And worst yet on a few occasions the status lights on the battery didn’t give any information! I tried calling your service line to complain and there was no immediate response nor was there any answer to why the app or batteries status wasn’t working. When did get a response it was weeks or a month later and who cares! Why can’t I have a physical switch at the batter to change the operating mode?

I’ve never written a review before but here it goes. For the first 3 or so months it worked great. Was able to see how much was produced every day and have a history of it. Then I noticed it stopped working for a bit and my history was lost during that time but at least it started to keep track of the history when it started working again. I lost about a month’s worth of history. Not too big of a deal but I called and they said they are doing a data migration and would be done in about 2-3 months. Quite a long time with no warning. Called again at the end of that period and they told me same thing. Would be done in another 2 months but same result. I eventually gave up and a couple months later it stopped keeping track of my data all together for the day. So I called again and what do you know, they are still migrating data. So essentially the app is almost useless to me. We’ll see if anything improves in the next month but poor experience so far with no promising improvements.
