Ecoflow STREAM (new generation)

Add-ons Bindings
1

Hi,

I’m currently trying to integrate a new EcoFlow balcony power system into openHAB using the official EcoFlow binding.

Setup:

  • Device: EcoFlow STREAM Microinverter
  • EcoFlow developer account with access key / secret key configured
  • Cloud bridge in openHAB is online and shows status ONLINE

Issue:

  • Device discovery does not find any devices
  • Manually adding a PowerStream thing is possible, but it remains in state UNKNOWN

From what I understand, the STREAM series (https://de.ecoflow.com/products/stream-microinverter) is a newer generation compared to the older PowerStream devices. The microinverter supports Wi-Fi/Bluetooth connectivity and cloud-based monitoring via the EcoFlow app, similar to PowerStream, but may use a different API model or device type.

So:

  • Is the EcoFlow STREAM series currently supported by the openHAB binding (and I am just too dumb to configure)?
  • Has anyone successfully integrated a STREAM microinverter?
  • Are there plans to add support for these newer devices?

Thanks in advance.

PS: I also attempted to use EcoFlow’s MQTT server, but could not establish a connection. The broker consistently remains OFFLINE in openHAB. Authentication appears to work (incorrect credentials produce proper authentication errors), but with correct credentials the connection still does not come online.

I was able to get the EcoFlow STREAM microinverter working in openHAB via the official EcoFlow developer API (MQTT). Since there is not much concrete information available yet, here is a minimal working setup. Currently, updates on are only received while the EcoFlow app is open. Without the app, only very few new MQTT messages are delivered (maybe every 13-16 min), and I have not found a solution for this yet.
