Integration with ORNO OR-WE-504

The purpose of this article is to present an example of integrating the energy meter with the Grenton Smart Home System. The following integration is using the Modbus RTU communication protocol.

The energy meter used in this example is ORNO OR-WE-504. Documentation of this device is available here.

According to the documentation - the default transmission parameters are as follows:

• address: 1;
• baud rate: 9600;
• stop bits: 1;
• parity: None.

This integration allows us to receive the following information:

• value of voltage and current;
• value of active and reactive power;
• frequency;
• value of power factor;
• value of active and reactive energy.

To complete this example, we need:

• CLU Z-Wave
• Gate Modbus
• ORNO OR-WE-504 

Configuration of the ModbusRTU virtual objects

1. Add ModbusRTU virtual objects on Gate Modbus module:

2. Enter the values of Embedded features in ModbusRTU virtual objects as follows:

* Voltage:


* Current:


* Active power:


* Reactive power:


* Frequency:


* Power factor:


* Active energy:

3. Send the configuration to the Gate Modbus module.

4. The read register values ​​look as follows in the myGrenton application:
