Z-Wave Water Flow Meter

I know there are many posts on people interested in doing a z-wave based water flow meter - however, I have not come across any clear solutions

I am thinking of taking the plunge with a Royallo pulse counter and a water flow meter with a pulse output

Has anyone done this with a Vera 3? I would love to know if anyone has interface the Royallo pulse counter with Vera 3. Don’t want to spend $$$ on this project to find out that the Royallo does not work well with the Vera 3

i found a device "Z-Wave Secure Water Meter " that would monitor water flow rate however it works in conjunction with another device. So follow the site below.
