To bad, last things where I remember this regular drop-out there was some kind of communication at play. HomeAssistant, MQTT or Adafruit IO stuff and the like. Look at this thread here, one person mentioning that his RTC seems the culprit and another mentions HomeAssitant.
No but, after reading every post and trying everything. I decided to disable temp sensor in reefpi which was the only other thing plugged into the robo tank. Reloaded and ph started working with no drop out. Enabled temp sensor ph continue to read correctly and has for a couple days now. I don’t understand why especially after doing 3 fresh install with the same problem. Question for you did you ever get the acs712 working if so would you mind sharing your code.
To go back to my problem even now that it’s working I still get an intermittent error message for under voltage. Sometimes the time stamp will be the exact time I check for errors even though I don’t get the red error message at the bottom of the screen.
