Remote heating system for my CAMP.

Bought an IoT Sim card and service from hologram.io

 This was the original plan...but the board on the left (SIM900) won't work anymore since the candian cell network has dropped 2G and moved to more advanced cellular comm.

So I decided to replace it with an old Android phone and and ESP8266 microcontroller.


Here are the new components.
Using a Cell phone for IoT communications over cellular is a big deal with lots of opportunity.
