Tongou SY2 163JZ / SY2 163JW Intelligent Circuit Breaker with Metering
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.
