RJ45 to RS232 COMM not working

Hey Guys
New to the forum here so I have my fingers crossed that I can find some help here.

I've recently installed a hybrid inverted (techfine 3kw) and all well with the installation, however for the life of me I cannot seem to understand why the COMM light on the RJ45 to RS232 wifi data logger won't come on immediately. Everytime I remove the RS232 datalogger and install it back in or restart it, the thing takes a few hours for the COM to be start working and provide me with data.

I have for the past 3 days trying to connect the data logger to the watchpower app & everytime I go through the setup, the app requires I restart to finalize setup. I'm failing at this ..

I'm currently using the SmartESS app & I don't have the "data chart" function to monitor my energy generated/consumed information.

The Wi-FI antenna on those are probably very cheap and doesn't reach more than 5 meters or through things. Is your router very far away? Are you splitting 2.4Ghz and 5Ghz SSID's. ESP32's and STMs prefer 2.4Ghz band and by splitting the Wi-Fi it tends to help these and other IOT things connect with more a stable setup. Note that all these inverters also are very electrically noisy. Can you move the dongle away from the unit with an extension cable. Hope that helps.
