SSR and other relays

Hi im stuck with my project when i try to configurate my devices. Im using a Raspberry pi 3 and a Arduino UNO slave. I got two solid state relays that i cant find, am i supposed to find these on the device configuration?
Im using uxcell SSR-25 DA 25A 3-32V DC / 24-380V AC Solid State Relays

SSRs cannot be automagically detected. BrewPi just returns a few default pins that were used on the original BrewPi shield as SSR outputs.
You should see those in the device list when you refresh, given that your script is running and there is successful communication with the Arduino.

Please not that we stopped officially supporting Arduino builds.
