Inquiry on Minimum Hardware Requirements and Controller Options for OpenEMS Edge (Latest Versions)

1

Greetings,

I’m working on a new project with plans to implement OpenEMS Edge. To ensure compatibility and performance, I’d like to better understand the minimum hardware requirements for recent versions of OpenEMS Edge, specifically regarding:

  • CPU cores

  • RAM (recommended and minimum)

  • Storage capacity and type (e.g., eMMC, SD card, SSD)

  • Supported communication protocols (e.g., Modbus, SunSpec, MQTT, HTTP/S)

  • Connectivity (Ethernet, Wi-Fi, CAN, serial interfaces)

Additionally, while I’ve seen references to Revolution Pi (RevPi) and BeagleBone Black as common controller platforms, I’m interested in learning about other widely used or more capable alternatives—particularly those offering improved reliability, scalability, or industrial certification (e.g., DIN-rail mounting, wide temperature range, long-term availability).

Could you please share insights on:

  1. Currently preferred industrial-grade controllers or SBCs running OpenEMS Edge?

  2. Any benchmarking or field deployment data comparing performance across platforms?

  3. Recommendations for cost-effective yet robust solutions suitable for real-world building automation?

Thank you in advance for your expertise and suggestions.

Happy New Year!
