Shelly Pro 3EM 3CT 63

The DIN rail clip snapped right onto my panel's rail and the three CTs fit around the mains without any rewiring hassle. I've been watching each phase separately in the app for two weeks and the numbers line up with my utility bill almost exactly.

Wiring the three CT clamps around my mains feed took about twenty minutes, and the readings match my utility meter almost exactly. Having single and three-phase support in one DIN rail unit saved me from buying two separate meters.

Snapped this onto the DIN rail in my panel and had per-circuit readings within ten minutes. The combined 3-phase CT means I only clamp one cable bundle instead of juggling three separate clamps, which made the install way less fiddly than I expected.
