I am trying to do the sump pump project by Felix
http://lowpowerlab.com/blog/2013/04/25/sump-pump-alert-with-moteino-hc-sr04/, replacing the RPi with a CentOS machine near the pump. I wish to log my progress and ask questions here.
With that, my first question:
From Felix's post it is not clear to me what sketch is loaded on the gateway moteino, when it is connected to the serial port of the computer, and receiving the signal from the sump pump node?
The gateway.py is running without any error on the CentOS, when I set the correct serial port.
Now the serial monitor is not registering anything, so I am wondering maybe I need to load the receive sketch there, please confirm.
