  1 | # ecoflow-iot-reverse
  2 | Trying to understand how to communicate with Ecoflow Portable Power Stations in **OFFLINE** mode.
  3 | 
  4 | ## Initial considerations
  5 | 
  6 | - Device cannot be reset to "factory settings".
  7 | 
  8 | - The ip of an Ecoflow Delta Max in offline mode is 192.168.4.1
  9 | 
 10 | ## Known open ports:
 11 | * 80
 12 | * 6093
 13 | * 8055
 14 | 
 15 | If you do an aggressive port scan with nmap (as soon as you touch port 6093, for example), it will exit offline mode.
 16 | 
 17 | - On port 80 there's a http server where can change the wifi connection parameters. 
 18 | If you delete the SSID, password and save, it will no longer connect to the internet.
 19 | 
 20 | - If you make a connection to port 6093, the device will return to IOT (online) mode.
 21 | 
 22 | - The app communicates with the device via byte-stream to port 8055.
 23 | 
 24 | - If you do an aggressive port scan with nmap (or touch port 6093), it will exit offline mode.
 25 | 
 26 | 
 27 | ## Communication with device
 28 | Classes that a priori take care of communication with the device from the app in offline mode:
