Getting started with micropython

  1. Download micropython from the official website preferably esp8266-20170108-v1.8.7.bin
  2. Copy it into the homeAutomation/nodemcu folder
  3. Rename the exampleConfig.py to config.py

To start mqtt server as a docker container and also start ngrok which exposes the mqtt services 5. Get the url from ngrok. It should look something like this
