Pimoroni's Flotilla First Steps

README.md

My first attempt (basically just a test) to use Node Red and Pimoroni's Flotilla Medium kit. It connects to a flotilla daemon via Web Sockets and display weather data into debug console. Inspired by this blog post. First value in the output is a temperature (deg. * 100), second - athmospheric pressure (hPa * 100).
