ecoflow-iot-reverse

Trying to understand how to communicate with Ecoflow Portable Power Stations in OFFLINE mode.

Initial considerations

• Device cannot be reset to "factory settings".

• The ip of an Ecoflow Delta Max in offline mode is 192.168.4.1

Known open ports:

• 80
• 6093
• 8055

If you do an aggressive port scan with nmap (as soon as you touch port 6093, for example), it will exit offline mode.

• On port 80 there's a http server where can change the wifi connection parameters. If you delete the SSID, password and save, it will no longer connect to the internet.

• If you make a connection to port 6093, the device will return to IOT (online) mode.

• The app communicates with the device via byte-stream to port 8055.

• If you do an aggressive port scan with nmap (or touch port 6093), it will exit offline mode.
