Changes 3.7.1:

Changes 3.7.2:
- adds a menu-option to the LCD-screen when a Sensorbox-2 with old firmware is detected; the menu option will enable you to upgrade your Sensorbox-2 firmware without having to disconnect it, and without having to connect to the USB-C connector. The “Setup” option will provide you with a portal (old fashioned SmartEVSE style) as an access point to your smartphone.
