Integrating Custom Energy Meters with OpenEMS!

Hi everyone,

I am exploring OpenEMS for managing energy systems and I have run into a question about integrating custom energy meters. I have a proprietary energy meter that supports Modbus communication but I am unsure about the steps needed to integrate it with OpenEMS.

I need to create a new OpenEMS component for the meter, defining its communication logic.
Implement the Modbus protocol to match the meter’s registers and data points.
Test the integration using the OpenEMS Simulator before deploying it in a live system.
However, I have some confusing points:

Are there any existing templates or examples for creating a custom Modbus-based component in OpenEMS: ??
How do I ensure compatibility with other OpenEMS components like the Energy Storage System: ??
Any tips for debugging Modbus communication in this context: ??

I would appreciate any guidance, best practices or relevant resources. Thanks in advance !!

Looking forward to your insights !!

With Regards,
Daniel Flutter
