WiFi Smart CT, No Cut Off Circuits: The SA1 is a WiFi smart current transformer designed for energy monitoring. It cannot cut off circuits. Only requires the 2.4GHz Wi-Fi during the pairing process

Easy Installation and Broad Compatibility: SA1 with 80cm (31.5in) neutral and live wires for quick connection. Compatible with most U.S. household circuit panels. Supports 120VAC single phase (L 120VAC+N) or 240VAC split phase (L 120VAC+L 120VAC) systems

Flexible Placement Without Space Limits: As a window-type current transformer, the SA1 uses its sensing hole to collect energy data from any single circuit within its 31.5in range, free from space or location constraints

Real-Time Unidirectional Power Tracking (AC Active Power Only): Monitor current, voltage, forward power, forward power consumption and CPU temperature via the Tuya/Smart Life app. Note: Not designed to measure reverse electricity; the app will display the sum of absolute values (forward and reverse electricity) if detected

Comprehensive Energy Data and Analysis: (1)Class 1.0 accuracy ensures reliable monitoring with detailed historical data (view by hour, day, month, or year). Easily track usage trends to optimize electricity consumption, suitable for homes saving on bills and businesses tracking energy conservation. (2)Export historical data via email for deeper analysis. (3)Clear electricity data with one click in the app, saving time and effort

Smart Alarms: Supports customizable alarms for over/undervoltage、overcurrent, overpower, CPU temperature and balance alarm. When thresholds are exceeded, you will receive immediate alarms. Enables quick response to potential hazards or inefficient usage to protect appliances and improve energy habits

Prepaid Electricity Management: Perfect for landlords and tenants. Supports prepaid power recharge, real-time current remaining electricity tracking per room and balance alarm. Encourages energy savings and cost control by promoting conscious electricity consumption
