The "Pool Monitor Card" is a home assistant plugin that display information of 1 to 12 pre-defined sensors of your swimming pool : temperature, pH, ORP levels and TDS but also if you need them : salinity, CYA, calcium, phosphate, alkalinity, filter pressure , free chlorine, total chlorine
Some sensors may need a minimum limit value. For example, Phosphates and TDS do not have a negative lower threshold since you just want to stay under a certain number as a high limit. I’ve configured TDS to be 0-2500 as the ideal range using setpoint and step but then it displays negative values for values under 0, which isn’t possible.
