Features 1. Automatic closing: the product can be closed automatically when the line is in normal operation, or can be set not to close when the line is incoming. 2. Leakage protection: When the leakage current is greater than the set value or when the person is electrocuted, the protector will automatically disconnect within 0.1S. 3. With metering function: voltage, current, power and electricity can be displayed 4. APP control: remote control by APP anytime, anywhere, shareable for multiple control 5. Timing: Schedule /Timing, countdown, cycle timing 6.Voice control: Yandex Alice ( )/Google Aistant/Amazon Alexa 7.Energy monitoringSet power unit price ,can caculate house device power consumptionDownload data to sheet Parameter Working voltage:110V-220V,50/60Hz Current type:10A-63A(optional) Wirele type:Wi-Fi 2.4GHz Support system:Android/iOS Q&A Q:does it work with the smart life application?
