Component Description
KWS-306WF – WiFi‑Enabled Energy Meter for Smart Home Management
The KWS-306WF is a compact, wall‑mounted sensor that continuously measures AC voltage, current, real power, apparent power, and energy consumption while transmitting data in real time to a Tuya‑based ecosystem. Powered by a 3.7 V Li‑Ion battery and a small μC‑based controller, the device delivers low power consumption (≈30 mA in sleep mode) and operates over 65–265 V AC, supporting both single‑phase residential and commercial mains.
With 0.2% accuracy for voltage (±0.5 %) and current (±1 %) measurement, the KWS-306WF provides reliable data for detailed household load analysis. Its built‑in Wi‑Fi (802.11 b/g/n, 2.4 GHz) automatically syncs to the Tuya Smart app, allowing users to monitor consumption on smartphones, set alerts, and trigger automation workflows via compatible smart switches or lighting systems.
- Voltage Rating: 65–265 V AC
