I have two probes and they will only work in the temp 1 plug. I have tried both probes in each plug and both of them work in plug 1 but neither work in plug 2. I have rebooted and reloaded but that doesn't seem to make a difference. I used the script to install Reef-pi. I have also done some research, but what I see doesn't match what I'm seeing in the instructions. How do you get the second temperature plug to work?
