Self configured energy meter
When your energy meter has configurable modbus addresses (or when your energy meter is not in the list of supported devices)
, we supply a feature to configure an energy meter yourself.
It's a process that allows you to set up the energy meter as a modbus slave, enabling it to communicate with the a-TroniX Controller .
Caution Caution WARNING: Special support terms apply:
*Please note that this feature is provided “as-is” and should be used at your own risk.
If you run into any issues or need dedicated assistance, we’re happy to help under a support contract.

Connect the meter to the a-TroniX Controller using RS485 or Modbus TCP.
For Modbus-TCP ethernet : Please follow For RS485 : Please follow
Also, check your meter's manual for the correct wiring and connection details and check if any settings need to be
changed to enable the modbus communication .
Collect the following information from your energy meter:
Modbus address : The address of the energy meter on the RS485 bus.Baud rate : The communication speed of the energy meter (e.g., 9600, 19200, etc.).Parity : The parity setting of the energy meter (e.g., None, Even, Odd).Register information : For each measurement you want to read, you'll need:
Register address (in decimal)
Data type (e.g., int16, uint32, float32)
Word order (if applicable for multi-register values)
Any scaling factor or offset needed
The type of measurement (e.g., voltage, current, power)
Open the a-TroniX Controller web interface and navigate to the energy meter configuration section.
Then, find the "Generic" driver:
Select the interface you'd like to use (RS485 or Modbus TCP).
You'll need to provide a JSON configuration that defines which registers to read and how to interpret them. The configuration follows this structure:
[ { "dataType" : "float32" , "address" : 3000 , "wordOrder" : "bigEndian" , "scaleFactor" : 1 , "measurement" : "actualPowerTot_W" }, { "dataType" : "uint32" , "address" : 3002 , "wordOrder" Each register configuration requires:
dataType: The type of data stored in the register (e.g., "int16", "uint32", "float32")address: The Modbus register address in decimalmeasurement: The standardized measurement name (e.g., "actualPowerTot_W", "importedAbsEnergyTot_Wh")
wordOrder: How multi-register values are ordered ("bigEndian", "littleEndian", "middleEndian", "reverseWord")scaleFactor: Value to multiply the raw register value by (default: 1)offset: Value to add after scaling (default: 0)bytePosition: Position within a byte array (if applicable)enumMapping: For enum types, maps values to stringslength: For arrays or byte fields, number of itemssigned: For numeric types, whether the value is signed We strongly recommend including at least:
Total Power (actualPowerTot_W)
Total Imported Energy (importedAbsEnergyTot_Wh)
Total Exported Energy (exportedAbsEnergyTot_Wh) if bi-directional
Enter the code in this place:
I see an error The input is strictly validated, and will not accept any mistakes:
The example above is not accepted because the user choose total power instead of actualPowerTot_W.
The following measurements are accepted:
actualPowerL1_W actualPowerL2_W actualPowerL3_W actualPowerTot_W reacPowerL1_VAr reacPowerL2_VAr reacPowerL3_VAr reacPowerTot_VAr importedAbsEnergyL1_Wh importedAbsEnergyL2_Wh importedAbsEnergyL3_Wh importedAbsEnergyTot_Wh importedEnergyTodayTot_Wh importedAbsReacEnergyL1_VArh importedAbsReacEnergyL2_VArh importedAbsReacEnergyL3_VArh importedAbsReacEnergyTot_VArh importedEnergyDeltaTot_Wh grossImportedEnergyDeltaTot_Wh importedReacEnergyDeltaL1_VArh importedReacEnergyDeltaL2_VArh importedReacEnergyDeltaL3_VArh importedReacEnergyDeltaTot_VArh exportedAbsEnergyL1_Wh exportedAbsEnergyL2_Wh exportedAbsEnergyL3_Wh exportedAbsEnergyTot_Wh exportedEnergyTodayTot_Wh After filling in the required information, save the configuration.
The a-TroniX Controller will now attempt to communicate with the energy meter using the provided settings.
Tip Tip For better organization, you can create your JSON configuration in a text editor first, then paste it into the configuration field. This makes it easier to edit and validate the structure before applying it.
