Who has fortrezz water meter / shutoff products?

Hey everyone,

I am thinking of investing into the fortrezz water shut off value and flow meter. I am curious who all has this and what do they think of the product ?

Can you make the water flow work with out hooking up to zwave ? my plan is to hook it up to HE, but want to know that it will work with out hooking it up to a zwave controller

When looking at the shut off value online, it looks like it has to be plugged in, does anyone know if it has back up power like a batter inside of it ?

I was thinking of this line of product of leak defense. Looking forward to anyone's feedback
