My implementation of GrovePI kit, to monitor temperature and humidity where I put my RPi. Requires 32-bit Raspbian for the GrovePi stuff to install.
- Display is plugged to I2C-1.
- Temperature sensor is plugged to D7.
- Button sits with D4.

Also set up a service via systemctl to start up the code, so it works headless.
