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
Is it possible to add a battery for devices such as Ico Ondilo (and probably also Flipr and iopool)?
