Please note that you need an Ecoflow powerstream (which is different from the Stream) to use the delta for charging and discharging on demand. Without the powerstream it will be a backup battery. Unfortunately these powerstreams are no longer available in shops and are expensive secondhand. I just bought one on the german Ebay (.de), where they are still reasonably priced. You will need a german address though to order with shipment or use an international shipping company in between.
The powerstreams were originally sold in 600W and 800W. Apparently the hardware is the same and you can upgrade them for free with a software update to 800W. More than 800W is not allowed through a wall socket.
I don’t know if the delta 3 works with this app. I bought a delta 2 with still 100% SOH secondhand. You could consider this as well. It looks less sleek, but had more ports. In the ecoflow app you can see the SOH in the settings.
Installed the App and connected my Stream Ultra and Stream Pro AC but its always saying, that they are inactive. Cant use any flows or change any settings. Any Ideas what to do or ist this the actual state of the App and nothing more to do yet ?
Workaround when EcoFlow devices no longer appear in “Add Device”
I’ve been having an issue with the EcoFlow Homey app where I can no longer add new EcoFlow devices. Existing devices in Homey continue to work, but when trying to add a device, no devices are found.
Creating new EcoFlow API credentials did not solve the problem.
To find out whether the problem was with my EcoFlow account/API or with the Homey integration, I tested the EcoFlow Open API directly from Homey using HomeyScript.
All devices linked to my EcoFlow account are returned correctly
In my case, the API returned all 15 currently installed EcoFlow devices
My PowerStream can also be read directly using /iot-open/sign/device/quota/all
So at least in my case, the EcoFlow Open API and API credentials are working correctly. The problem appears to be related to device discovery/pairing in the Homey EcoFlow app.
As a workaround, I now bypass the EcoFlow Homey app for my PowerStream.
I have a HomeyScript that communicates directly with the EcoFlow Open API and updates Homey Logic variables with values including:
PV1 power
PV2 power
Total PV power
AC/inverter output
Battery state of charge
Battery charge/discharge power
Power consumption/demand
Battery temperature
PV temperatures
The script is currently running automatically once per minute and is read-only, so it does not send any control commands to the PowerStream.
This is working successfully on my Homey at the moment. I’m monitoring it for stability before moving the existing Homey flows that still depend on the old PowerStream device over to these new API values.
Important: your EcoFlow AccessKey and SecretKey should remain private and should never be posted on the forum. In my setup they are stored locally in the HomeyScript.
If other people are experiencing the same “no devices found” problem, it would be interesting to know whether the direct EcoFlow API also returns their devices correctly.
If there is interest, I can share the complete HomeyScript and setup instructions once I’ve confirmed that it remains stable.
