Error WiFi ...no matching function for call to 'WiFiManager::WiFiManager(Stream&)' about wemos-matrix-shield

[dragondaud]

That error is caused by not using the development version of WiFiManager. The build.sh update script will install the correct version if you use "-u" to update libs. I recently updated it to also use new versions of core and other libs, too.

Thank you, thank you!
You've helped me a lot. It never occurred to me to look in the development area.
Now the compilation went through and I get a time display. But two things are not so good yet:

1. The clock is two hours slow. 1 hour probably because daylight saving time is not taken into account, but the other hour? Europe/Berlin is given as country.
   There is still the possibility to enter a timecode in the web interface, but where do I get it from?
2. in the left corner an error code is displayed in red: 401 and sometimes 404. if I am right, this indicates missing weather data, because the key I entered in OpenWeatherMap is not accepted.

With kind regards

Hello!
You can forget my last question, I found everything. The clock was running for a while, but when I wanted to show my grandson how to connect the clock to the wlan via the web-interface, it didn't work anymore. The web-interface does not transfer data anymore. I can tell that because when I call save config in the interface, the "config.json" is empty. It is also a different interface, because e.g. the color selection looks different.
When I restart apply config, above the clock (it is running, without timecode and without weather data with the wrong zip code and in english) in red letters appears: "config failed". That was it.

With kind regards

I think this one is not related to this shield but on the clock software, should be fixed with latest version.
