Trying to understand how to communicate with Ecoflow Portable Power Stations in OFFLINE mode.
-
Device cannot be reset to "factory settings".
-
The ip of an Ecoflow Delta Max in offline mode is 192.168.4.1
- 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.

This was tested on an EcoFlow Delta Max, when the Android app would not allow 31-char WPA2 password.
This procedure is based on information from GitHub Issue v1ckxy#2
-
Hold IOT button to enter offline mode
-
Connect to EcoFlow WiFi network with computer
-
(recommended) Fetch existing WiFi config as sanity check
curl -X POST -d '{"action":"getSTA"}' http://192.168.4.1
- Carefully craft the command to set the new SSID/Password
curl -X POST -d '{"action":"setSTA","data": {"ssid": "SSID_PLACEHOLDER", "psw": "PASSWORD_PLACEHOLDER"}}' http://192.168.4.1/
For example: SSID = My Network Password = 123abc123ABC
curl -X POST -d '{"action":"setSTA","data": {"ssid": "My Network", "psw": "123abc123ABC"}}' http://192.168.4.1/
- (recommended) Fetch applied WiFi config as sanity check
curl -X POST -d '{"action":"getSTA"}' http://192.168.4.1
- Disconnect from WiFi and reboot EcoFlow, allow it to connect to WiFi online-normally
