### 1.  Introduction

<div align="left"><figure><img src="/files/ttjzKBYKXuiPFVUEVfJI" alt="" width="239"><figcaption></figcaption></figure></div>

SRS01 2PM is a compact dual-channel relay switch featuring independent power monitoring and wireless connectivity. It allows real-time control and monitoring of two separate AC loads, making it suitable for dual-circuit automation scenarios.

#### Product Highlights

* **Mini Dual-Relay**: Ultra-compact (38×42×16mm) fits behind switches. Controls two independent circuits (10A/ch, 16A Total) without changing your original switch style.
* **Independent Monitoring**: Measures real-time power and energy for each channel separately, providing precise per-device data unlike common total-sum solutions.
* **2-Channel Control**: Compatible with both toggle and momentary switches. Independently control two loads via App or 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.

#### Typical Applications

* Smart Lighting: Install behind the roof or wall switches

### 7. System Integration

Products equipped with different communication SOC firmwares connect to different systems and cloud platforms. Users can select the appropriate version based on their specific application requirements.

{% tabs %}
{% tab title="Tuya WiFi " %}
The Tuya WiFi version can only be integrated into the Tuya Cloud using Tuya's encrypted MQTT communication. It cannot be integrated with any third-party cloud platforms, ecosystems, or gateways.

However, Tuya's Smart Life App is user-friendly and straightforward, making it ideal for entry-level smart home users who prefer simplicity and basic energy consumption monitoring.
{% endtab %}

{% tab title="Standard Zigbee 3.0" %}
The Standard Zigbee 3.0 version can seamlessly connects to third-party gateways. Thanks to the standardized application-layer integration of Zigbee 3.0, it is highly convenient and widely applicable for both residential and commercial building projects.
