I,
No one here can tell if adding 2.24 ppm of chlorine to your pool each day is too low, too high, or just right.. Only you can tell that.
This whole site's main purpose in life is to show other pool owners how to test the chemicals in there own pools and then decide if they are correct or not..
Besides testing, the key to the whole process is keeping your FC (Chlorine) and CYA (Stabilizer) levels in relationship with one another, per the saltwater portion of this chart.
FC/CYA Chart
I assume that you do not test your own pool water, and currently have no clue how much chlorine your pool uses each day.
Back to the faulty readings.. As a test, I suggest that you change your
Pool schedule from 9 pm to 9 am... to 9 am until 9 am.. That will run the pump in the pool mode 24 hour straight.. During that time, see if you get any alerts.... If so, how often, and at what time do you get them. You only need to do it for one 24 hour period.. This will tell us if the problem is your schedule or the cell..
Cells generally last about 5 to 7 years, but the harder you run the cell the more of it you use.. Who normally adjusts the cell's output? Do you use a "pool guy"?
If you can stick your phone under the cell and take a pic or two, there should be a label with a S/N which will tell us how old the cell is.
Thanks,
