Tongou SY2 163JZ / SY2 163JW Intelligent Circuit Breaker with Metering: Built-in measurement of load current, voltage, and power consumption
This Tuya Intelligent Circuit Breaker is for the homeowner who wants to monitor energy use and control appliances remotely. Think of it as a smart upgrade for your electrical panel, letting you check on a basement freezer or schedule a water heater from your phone.
Beyond basic home security, it offers peace of mind through energy management. You can see real-time power consumption, so you know if a device is drawing too much current before it trips a breaker. The built-in measurement tracks usage by hour or day, helping you spot inefficiencies. For example, the app alerts you to unusual spikes, so you can address issues like a faulty appliance quickly.
Control it wirelessly with the TuyaAPP or use voice commands via Alexa compatible systems. The three timing modes automate tasks, like turning off lights on a loop to save energy. Comprehensive protections against over current and voltage keep your devices safe, with automatic disconnection if thresholds are exceeded.
