Feature:1. MONITORING ENERGY CONSUMPTION: If the user has a solar photovoltaic system in the home, after installation according to wiring diagram, the smart energy meter can monitor the electricity generated by solar photovoltaic system and energy consumed by city grid2. APP MONITORING: After the smart energy monitor is connected to WiFi(WiFi can be connected to the Internet), users can monitor the device status anytime and anywhere on the for tuya APP or for SMART LIFE APP(mobile phones can get internet signals)3. WITH SENSORS: For tuya smart energy meter come with 2 300A current transformer CT clamp sensors, current measurement range is 300A+300A, efficient and practical4. MONITORING CONTENT: WiFi smart energy meter real time monitor voltage, current, power factor, active power and frequency, operating voltage is AC90250V, and the measuring current is 0.2300A5. DATA STORAGE: WiFi smart energy monitor allow you to view the hour, day, month, and year energy consumption records on the APP, and the APP can keep the records for more than 1 year, support for click and run and automation of other for tuya devices6.
