Can anyone help with the Solarman app?

Hi ​@Johanhendrik , where are you based? Your image suggests not the UK.

As this is a UK based forum our technical understanding may not match your equipment 

I had a similar issue when setting up a small solar system. Before changing the app settings, I found it useful to check that the inverter, Wi-Fi logger, and data logger were all connected correctly. A weak network connection can also stop the app from updating properly.

I've also been reading about how different countries support residential solar adoption. In my case, I recently looked into the *removed by mod* to understand how households can check eligibility and registration for government-supported solar projects. Although it's a different topic from Solarman, it's interesting to see how software and online tools are becoming an important part of managing home solar systems.
