    My solar died for 6 months, so I built a watchdog▲15

    Hi HN, Shawn here. My rooftop system lost about half a year of production and nobody told me. Not the installer, not the monitoring app, not the utility. I found out from an electric bill that made no sense, then spent weeks digging through the monitoring portal by hand. SunRanker is what I wished existed that day. Connect a system once (Enphase OAuth, or a SolarEdge site ID plus API key) and it reads production daily, shows it in plain language, and emails you when something actually changes. Three alerts only. The connection broke, the monitoring went quiet, or output has been well below…
