Are they internittent? Like the sensor works before and after?

Look at your wiring and doublecheck it. Maybe something worked loose.

Nope like everything was working just fine and then all the sudden as i was walkin out the house to drive two states away i started getting these messages. They are continuing. Ive check wiring. Even rebooted

Try deleting the sensors, reload then add them back in and see

Ok deleting them and redoing them solved the issue. Curious as to why it happened though.

Thats not the only thing. Something happened to my ATO that caused it to stay on and overfill my tank by about 5 gallons. There are redundant sensors as well. Not sure why that happened.

Corruption of the database, probably from a power blink or the like. Sometimes raspian has trouble with time issues and files during a reboot dont get the right time stamp.
I solved the issue with the addition of a real time clock that hooks to the i2c bus...if raspian loses network time, the real time clock keeps the time good so files dont get weird time stamps.

Read my thread to see how i added one

I have read about that a couple days ago. Thats a great idea and i think i even have spare RTC laying around. I still need to seen ranjin that ph probe board

Was there any sudden reboot or power outage ?

Not that i know of it started right there when i was standing in front of the tank.
