### 1. Device Overview

This profile applies to the following smart meter models. All devices communicate via the standard Zigbee 3.0 protocol with the default Endpoint set to `1`.

> 💡 **User Best Practices**
>
> 1. **Default Reporting Configuration**: For all reportable attributes, the default configuration is `Report Min Interval: 30s`, `Report Max Interval: 30s`, and `Report Changeable: 0`. This means the device is factory-defaulted to automatically report its data every 30 seconds.
> 2. **Multipliers & Divisors**: It is highly recommended to read all multiplier and divisor parameters **only once** upon device power-on/network joining. **Do not** configure reporting for these static parameters to avoid network congestion.
> 3. **Calculation Formula**: `Actual Value = Raw Value * Multiplier / Divisor`

### 2. Common Clusters

The following Clusters are **identical** across all Single-Phase, Two-Phase, and Three-Phase devices.

### 4. Metering (0x0702)

This Cluster is used to read the accumulated energy data (Delivered/Received energy).<br>

> 💡 **Implementation Note for Multi-Phase Energy** In the standard Zigbee ZCL specification, the `Tier 1/2/3` attributes are originally designed for Time-of-Use (TOU) pricing. To simplify gateway integration and keep all data unified on a single Endpoint (EP1), we have mapped these Tier attributes to represent the individual phase energy:
>
> * **Tier 1** maps to **Phase A**
> * **Tier 2** maps to **Phase B**
> * **Tier 3** maps to **Phase C**

### 5. Custom Cluster

#### Modbus CFG (0xFC00)

This is our proprietary Custom Cluster, specifically designed for configuring devices with Modbus functionality.

> ⚠️ **Prerequisites & Requirements**
>
> * **Applicable Models**: Only **SDM01 Combo (3-phase version with Modbus)**.
> * **Version Requirement**: Requires Firmware V10+.
> * **Authentication**: Reading and writing to this Cluster requires the Manufacturer Code `0x1216` to be included in the Zigbee payload.
