There was no devices reading so I ended up replacing the Arduino & Pi and it looks like the Arduino board was stuffed so i’ll just use my other Pi for another little project i have in mind.
I just had a whole pile of problems with setting up the wifi after formatting my SD card and reinstalling everything. I finally got it sorted today, and just managed to get BrewPi installed super simply. Thanks a bunch. Lets hope my relays work now, otherwise i’ll be waiting a couple of days while new ones turn up haha
All good, i need to make a starter for the next beer anyway!
Thanks Elco & all above for the posts. Its helped me understand a lot more about the way to work in Terminal/SSH
Just to give an update, uninstalling the heating and cooling devices cleared the device itself and when i reapplied the changes it all clicked on like it should. So pumped to have it back up and running, i also have enough spares to build a second one. Might be able to control my serving fridge a little better and hook up a tower cooling system or something.
