I currently use the Arduino Yun but am testing the Arduino Mega, Yun mini and Uno Wifi.
This is my brew setup,
With Solid State Relay

The Arduino Yún is now discontinued but you can use this replacement called Seeeduino Cloud
Just finished a waterproof prototype!
It's Back! Arduino Yún Rev 2 is set to be on sale April 23, 2018!
I really enjoyed your project. Have you tried using the arduino uno with network card?
I would love to use your brewing automation ..
Sorry for writing mistakes, my language is Portuguese .. I'm from Brazil.
Ronald Yea you can use a Dragino Yun Shield with an Uno.
Hi...its a nice board the Yùn–a small Linux machine and a microcontroller in a small Arduino form factor–found its way into hundreds of thousands of projects and professional applications. Last year, we decided that it was time for a refresh and began working hard to develop a true open-source design, with more compelling features and better overall software support.
