To ensure that your meter can be smoothly integrated into the HEMS system, it is recommended to follow the steps below:
Step 1 – Confirm the connection method and interface parameters of the meter to the HEMS system
- Modbus-RTU communication has been established between the HEMS Controller and most models of Schneider Meter. You can use RS485 wiring to connect the two devices.
- Refer to the Schneider Meter User Manual to confirm the exact location of the RS485 interface, as well as the factory default parameters and the method for modifying them.
Step 2 – Establish the correct connection between the meter and the HEMS Controller
- Based on the RS485 interface parameters of the Schneider Meter, connect the RS485 cable to the corresponding RS485 interface of the HEMS Controller.
- (The interface parameters and configuration method for the HEMS Controller can be found in the detailed examples below or in the User Manual and other materials.)
Step 3 – Enter interface parameters in the enjoyelec app
- After completing the wiring, power on the devices. Open the enjoyelec app to bind the device and enter the interface parameters that match the actual setup.
- (For detailed instructions on configuring the app, please refer to the User Manual.)
- Once the configuration is complete, the Schneider Meter will be integrated into the HEMS system, allowing you to perform functions such as querying and controlling the device via the app.
Example
The following provides a detailed explanation of the process for integrating the meter into the HEMS system, using the Schneider Meter model IEM3155 as an example:
Step 1 – Confirm the connection method and interface parameters of the meter to the HEMS system
IEM3155:

- The communication interface of the Schneider Meter is located at the bottom of the device. By consulting the meter’s User Manual, you can find that the Communication interface (COM) marked as ‘C’ is located as follows:

- According to the user manual, the COM port marked as “D0″&“D1”are used for RS485 communication. The pinout of the RS485 connector is shown in the diagram below:

- The baud rate of the RS485 port on the Schneider Meter is typically set to 9600 by default,and the address is 1.
If you need to verify or modify relevant parameters, you can use the Schneider Meter user manual to make changes.
Step 2 – Establish the correct connection between the meter and the HEMS Controller
When connecting the meter to the HEMS Controller via RS485, it is essential to ensure that the port parameters of both devices match. The port location for the controller with a baud rate of 9600 is shown in the diagram:


(For selecting a different baud rate, please refer to the user manual for verification.)
- When wiring, please pay attention to the color differentiation of the A and B cables to ensure that the port wiring sequence on the Controller side correctly matches the port sequence on the meter side.
- If a different baud rate port is required, you can refer to the User Manual to locate the corresponding port, or use the enjoyelec app to set the port parameters on the Controller.
Step 3 – Enter interface parameters in the enjoyelec app
After completing the physical connection between the meter and the Controller, the relevant parameters need to be configured in the enjoyelec app:
- In the app, select the device type, brand, and model of the device connected to the Controller.
- Configure the communication method between the Controller and the meter in the app, including the communication protocol, physical port number, port parameters, etc.
- Once the parameter configuration is complete, send the configuration information to the Controller. The Controller and the sub-device will begin pairing and establishing a connection, enabling data collection and control of the sub-device.
