The new(ish) solar panels on the roof came with an monitoring app from SunPower which, naturally, stores lots of information about the house in the cloud somewhere. I'm sure that their management of, say, the realtime consumption data is entirely secure, nothing to worry about there.
Today the app said that we were producing nothing, despite this being a beautiful cloudless Colorado day. Some digging into their web site turns up a page (
https://us.sunpower.com/solar-resources/home-solar-system-troubleshooting-questions-and-answers) suggesting to log out of the app and back in; failing that, the trick is to uninstall and reinstall. Sure enough, that worked. Quality engineering there.
My intention to figure out how to get the data directly out of the monitoring system and short these people out is growing...
