Oh, man this seems to go on for 2 years.
I just got mine and installed it five times and did all the settings above mentioned, it's just showing the blue light and no data.
What I did:
1. installed Growatt 12k inverter
2. Added annoying app to phone and the Wifi module. a week after 09/21/2023
3. It showed up in the plant as item, but never showed any data.
4. Reset and re-added five times, but no connection
5. When I start the app the scanner comes on first place and says no device, even though it's in the list and the blue LED is on.
6. Like many other videos and instructions show to use dataloggers Wifi, but the dongles wifi doesn't seem to work.
Found this, you need to press the button twice. Not working yet, but got the Wifi from the dongle:

TROUBLESHOOTING / QUICK REGISTRATION PROCESS:
Note: If after completing the registration process by following the manual, the LED flashes blue, but are unable to view any data, we need to make sure the Wifi Module is connecting to the USA Server. (Just been created recently)
NOTE #1 : a press of more than 6 seconds duration resets the Wifi Module. (Tiny hole, use a sharp pointed object)
NOTE #2 a press of less than 0.5 sec puts the Wifi Module into Access Point Mode (Thus transmits its Wifi SSID). (Tiny hole, use a sharp pointed object)
This is also an alternative registration method:
- Connect Wifi Module to USB Port on inverter
- Insert pin or another tiny sharp object into the tiny LED hole for 6 or more few seconds, until the Light is steady White(ish)
- Insert pin or another tiny sharp object into the tiny LED hole for less than 0.5 seconds, until the Light is steady /flashing White(ish)
- On your phone or PC connect to the Wifi Name that matches the serial number on the Wifi Module (Hint -also on the box)
- Sometimes your phone will ask if it is ok to connect to this network without internet access (affirm this and connect anyway)
- From your phone or PC browser, type in the “192.168.10.100” IP address just as shown here, and go.
- log into the blue login screen “admin” password “12345678” see example: http://watts247.com/manuals/gw/WifiConfig-0.jpg

7. This brought me closer. The first time I had the dongle states with online, good quality of service, but still not reporting service. It's like a dead dongle connected to a server.
Update 10/01/2023
No problem to add and remove the datalogger to the plant either way, but it just doesn't deliver any data to the server, even with connection status excellent. I guess I have to return that unit.
