The Icare. But it also tests your water and tells you what to add but you can watch your water from anywhere. shopthehottublady.com/collections/icare-monitors
The iCare is still better though, right? I mean, the iCare does this and so much more... and you don't need to be near the controller to see the temperature either.
There are some serious differences between the Icare and the IBS-P20R. The IBS-20R is just a thermometer and it allows you to see it inside….. and it is super affordable if you looking for temp only this is a great accessorie
