Finally got accurate per-phase readings for my workshop’s machinery, and the real-time data in the app is spot-on—no more guessing which circuit is eating power. Setup took a bit of fiddling with the wiring, but once it was live, the refresh speed made it worth the effort.
I’ve been monitoring my shop’s three-phase load for a week now, and the real-time readings on the web interface are spot-on compared to my utility meter. The compact DIN-rail form factor made it easy to fit into my crowded panel. One less thing to worry about.
Set it up in my panel in about twenty minutes and the live data on the app is incredibly smooth. The three-phase readings update fast enough to watch my heat pump cycle without any lag. Exactly what I needed for the shop.
