OK so I had my first major issue with reef-pi. My ATO has been working great and doing it's job keeping my water level where it needs to be. Last night the power went off for about an hour and when reef-pi restarted the ATO ran until the ato container was empty dumping about 1 1/2 gallon of water into the system.
I just noticed it when I went this morning to fill my ATO and saw the pump was still running and the container was empty. Not a huge deal as it only changed my salinity from 1.026 to 1.025 and the pump didn't burn up.
I'm just glad it didn't happen when the reservoir was full. So after a water change with some strong salt mix I got my salinity back to where it needs to be.
I did some testing on the sensor to check that it was working properly and found that when I put the sensor in water the outlet controlling the pump is staying on no matter if the sensor is in or out of the water.
Could it be the sensor got damaged with the power going off? Or maybe something in the software?
I seem to remember reading somewhere that there was an issue with these sensors not responding correctly if reef pi starts and the sensors are submerged but I can't find the post now in the mega thread.
@Ranjib any ideas?
