Hey, I just noticed my PH probe stopped reporting data a few days ago.
What should I check first?

Hi, sorry to hear, can you try running the following command in the Pi terminal, it should print a list of addresses, 40, 70 and 63.
i2cdetect -y 1

Ok, looks like the address for pH changed to 0x6f or 111.
In reef-pi can you first disable the pH on the pH tab. Then go to configuration tab, then drivers tab and edit the pH driver. You'll see it has address 99, change that to 111 and save. Then go to the admin tab and press the reload button. Now go back to pH tab and enable circuit and it should be working.
