Is there any tools that have z-wave capability that has the ability to test the water for chemical levels, such as chlorine, etc?
The only thing available is replacing your controller unit for your pool controls. And I’m not sure once installed what Vera would output to you. So if the unit will report chlorine I would assume somewhere on Vera you should be able to see the readout. Same thing with salt as an example.
Correction to the above, it’s www.mysensors.org.
