Shelly EM + 50Aクランプは、住宅や商業施設での電力消費を監視するために設計されたコンパクトなエネルギーメーターです。付属の50Aクランプセンサーを使用して単相の電流を測定し、Wi-Fi経由でリアルタイムデータを提供します。
Setup took me under ten minutes even though I'm not super handy, and the live readings in the app update fast enough that I can see the washer kick on in real time. The 50A clamp fit my main panel wire without any wrestling, which was my biggest worry.
The 50A clamp is the star here—it snaps on firmly and the readings match my multimeter within a hair. Setup took maybe ten minutes and now I can see exactly what that old fridge is pulling from bed.
Glad I grabbed the 50A clamp version instead of a smaller one — the sensor slides right over my main breaker wire and the app updates almost instantly. It’s nice to finally see exactly which circuit is eating all the power each month.
