[Possible feature] WiFi Manager #22
Description
It might worth looking into the WiFiManager. It would allow much easier configuration (even after deployment), and would be much easier to experiment with different layouts.
The idea is to set up the configuration via the Wifi Manager using the web UI (WLAN access, timestamp, number of short and all-day events, etc), so that config can be saved and stored on the ESP and every time it triggers the Google Script it would be able to send that config in the request body. Based on that config the Google Script could create a response dynamically.
Possible failures with the rendering might happen with a bad config. Need to find a way if it is possible to avoid...
