Shelly EM + 120A 클램프는 전력 소비 모니터링을 위한 에너지 미터입니다. 이 장치는 전류 측정용 120A 클램프를 포함하며, Shelly EM 시리즈의 일부로 릴레이 기능을 제공합니다.
Setup was easier than I expected—the clamp snapped right around my main line and the app showed live wattage within a couple minutes. The 120A rating gives me plenty of headroom for our whole panel, and the data updates feel instant when I flip on the dryer.
Took about ten minutes to wire into my panel, and the 120A clamp reads are spot-on compared to my utility meter. The app updates fast enough that I can watch the dryer kick on in real time, which is oddly satisfying.
Installed it in my breaker panel and paired it with Home Assistant in under ten minutes. The 120A clamp reads my whole-house draw accurately enough that my utility bill matches almost to the digit each month.
