I decided to add MQTT messaging to to create a couple publicly available dashboards.

When I changed the code to add the Adafruit dashboards, I updated some libraries which led to no end of fun. Long story short, one sensor was sending data to pin 2 on the Huzzah. The updated libraries broke this. When I tested, I assumed my terrible build quality had created the problem. Much testing later, I solved the problem by moving the sensor to pin 12.

There are now two public dashboards:

a week's worth of graphical data


The current (within ~30 minutes) readings.

The updated code has been pushed to my the master branch of my github repository.
