Arduino and 8chanel relay


I looking into the possibility to expand my fermentation control. I currently use a RPI 3, arduino(two sensors and two SSR) controlling one chamber. And not to experienced with Brewpi, arduinos and the setup,
What I want is to control two separate chambers: with heat and cooling function, temperature sensor
And a fridge with temperature sensor and cooling. Or do I need multiple arduinos?

Could this be done with one arduino and a 6/8 Chanel relay? And three temperature sensors.


The software does not support multiple control loops. You need 2 Arduinos.

For the Spark we’re working on an update to support multiple control loops, but for the Arduino we will not release any updates.

Thank you!

So I would have to do a three arduino setup with three two channel setups then.
