SRS 1PM

Single-Channel Smart Relay Switch with Power Monitoring

SRS01 1PM is a compact single-channel relay switch with integrated power monitoring and wireless communication. It provides real-time measurement of voltage, current, power, and energy, making it ideal for smart home automation and lighting control.

- Mini Retrofit Design: Ultra-compact (38×42×16mm) fits behind existing switches. Supports 16A max load, keeping your original switch style while adding smart control.

- Real-time Monitoring: Measures real-time voltage, current, power, and energy for precise consumption tracking across home and commercial devices.

- 16A Control Support: Works with both toggle and momentary switches. Control lights via App or physical wall switch simultaneously without conflict.

- Flexible Connectivity: Available in 3 editions to match your needs: Tuya Wi-Fi (Easy App), Matter over Wi-Fi, or Open Wi-Fi <-> Standard Zigbee 3.0 Switchable.
- Built-in Safety: Equipped with over-temperature, over-current, and over-voltage protection to extend product lifespan and minimize failure risks.
