I’ve been working to integrate my @Smartthings installation with my Big Green Egg smoker. My first working take involves putting a raspberry pi out at the BBQ with a little daughter card that reads analog values off of thermistor probes and converts them to digital temperature values that I read on the Pi, and expose as a web service. The Smartthings app script then reads the values off the pi.
It seems like I should change it around to have the BBQ probes be just values I read off an Arduino + Thingshield, and put more logic up in the app itself.
I’m trying to figure out how to get started. The shield script itself should be pretty straightforward given that it’s just reading values off the probe board and doing a little compute to convert to Fahrenheit values - what I’m trying to figure out is how to map my raspberry pi daughter board to the Arduino itself.
Suggestions? Any possibility someone has already done this?
