   - add light sensor to monitor illuminance --> low priority
   - improve reading by either: reduce power on time of WiFi module (batch logging)
     or by compensating for board own temperature --> WiP
+  - use a local toolchain to compile mbed projects (with trueStudio) --> WiP 
   - add option to choose location from a list and update location tag
   - incrementally convert the project to electric energy monitoring:
         - read 2x simultaneous adc channels using DMA
