Hello everyone My name is Francesco, i'm building a reef pi for my brother's salt water tank. (already had made him one a few years back, but the sd card just crapped out on it). the setup is Rpi zero W, raspbian lite (but i might reflash with the full recommended programs.) it has a temp probe and ph sensor. just installed reef pi 4.2
here are the issues that im running into, i get an error with the ph (temp works perfect) when i enable it i get:
" {"error":"stats for id: '1' not found"} | HTTP 404 " and in the reported errors i get
" ph subsystem: Failed read probeHError:write /dev/i2c-1: remote I/O error "
the calibration of the ph (when its disabled) i don't get the pop up to do the beginning, mid and end point calibration
here is the process i followed:
i followed the adafruit tutorial for the main installation and ph installation with the exception that i have a electrically isolated ezo carrier board from Atlas scientific with the ph ezo, i didnt add the pullup resistor (i believe the board already has it) i've followed the troubleshooting guid on reef-pi on github, i can post the results of " sudo journalctl -fu reef-pi.service". i've also followed the very first post by Ranjib in this thread, and also the atlas raspberry pi sample code (which with that one i do get reading from the ph in ssh)
sorry for the long post i've tried looking through many posts and i'm a brick wall now. maybe installing an earlier version of reef-pi?
thank you all for your help
