3. **Add a new device**
   
   In the **Add Device** wizard, start with the device configuration:
   
   -   **Device type**: select the type of device you want to add, for example PCS, BMS, Energy Meter, or PV inverter.
   -   **Brand**: select the manufacturer of the device.
   -   **Model**: choose the correct model from the list.
   -   **Device name**: enter a clear and unique name, for example *PCS1*, *BMS Rack 2*, or *Main Meter*.
   -   **Parent device**: select the parent device in the electrical hierarchy, typically the main meter.
   -   **Description**: optional notes about the device or installation.
   
   Click **Next** to continue.

5. **Configure device communication**
   
   Define how the EMS communicates with the device:
   
   -   **Protocol**: select the communication protocol, for example *Modbus TCP/IP*.
   -   **IP address**: enter the static IP address of the device.
   -   **Port**: enter the communication port, commonly `502` for Modbus TCP.
   -   **Slave ID**: enter the Modbus slave ID. The default is often `1`, unless specified otherwise.
   
   Optional actions:
   
   -   **Test**: Click **Test** to verify communication before saving.
   -   **Previous**: Go back to adjust device details if needed.
   
   Click **Save** to add the device.
