Water Valve Shut off

Hi, I was wondering if there are any water valve shut off devices that support larger pipes? I have a backflow prevention device right next to the main valve which is bigger than the 1.25" maximum on the Qolsys IQ Water Valve product. (I think I could attach one side to a ~1" diameter pipe, but then the backflow device would be larger on the other side.

Has anyone had success pairing a non-Qolsys device to the iQ4 / alarm.com or found a way to make the Qolsys IQ water valve work on a larger diameter pipe?

Would it work to create some sort of secondary mounting point perhaps and attach it to that vs. directly to the pipe?

Alarm.com compatible devices can be found here:

For mounting purposes if you have special considerations, it is strongly recommended to contact a plumber regarding making changes to the plumbing.

Can you post a photo of the valve and the backflow prevention you are referencing?
