Took a little bit longer to accommodate your recent changes.

• Have a look if you like the new folder structure: the idea is to move from ArduinoIDE to PlatformIO
• Main changes are in commit "Improve WiFi & add influxdb support"
• Other changes are:
  • Notes about required external libraries
  • Minor code cleaning
  • Add some functions for better readability, e.g. battery status
  • Some variables in the loop() are better defined as global vars
  • Avoid overflow by adding space for 0-termination
  • More streamline refreshing of the display
  • Simplified CO2 update check

Issues:

• when power is connected, there is a short display glitch (see comment)
• when power is disconnected: sometimes reboot or reboot loop (ideas for debugging this w/o Serial?)
