Kodak inverter WiFi module

The Kodak OG3.6 Max has a build in WiFi module. It is impossible to get even to the setup page on the WatchPower App to configure the WiFi to connect to an access point. After consulting with a few people who has similar problems with the Kodak WiFi setup, they overcome the communication problem with a custom made Raspberry PI module to communicate with the inverter. All the manuals "sell" the same setup story. I have come to the conclusion that it is impossible to use the build in WiFi and it is a total waste of time, money and effort to try to get it working. Shop around for a better inverter where everything is working as advertised.
