binding with SolarEdge and EVCC

1

Hi,

I am using the SolarEdge binding in openHAB together with EVCC for energy management.

The system works correctly, but I notice significant latency in live power values (PV, battery, consumption). This causes issues with real-time applications like EVCC, where energy balancing depends on synchronized data.

Current setup:

  • SolarEdge system (master + slave inverter)
  • openHAB SolarEdge binding (cloud API)
  • EVCC using openHAB data

Problem:

  • Data updates are delayed (15–30 seconds)
  • Leads to inaccurate or lagging energy flow visualization in EVCC

Questions:

  1. Is there a way to get faster / near real-time updates from the SolarEdge binding?
  2. Are there plans to support Modbus TCP (local inverter access) in the binding?
  3. Any recommended approach for real-time energy monitoring with SolarEdge in openHAB?

Thanks!

  1. via cloud? I don’t think so. Delay is inherent there.
  2. No. But you can use the generic Modbus binding instead of or in parallel to the SE binding.
  3. my own HEMS https://storm.house/ems :rofl: . But beware it’s commercial.
    In short, for SE devices it uses the Modbus binding.
    And do the visualization in OH, there’s some nice PV widgets on the marketplace.
    No need for EVCC on that part.
