I agree with the smoke detectors, I feel the listeners are just a way to fill a known gap. The First Alert z-wave would be perfect if they could be hardwired. I’m due to replace my current hardwired smoke detectors (7) and want them to integrate with my Ring alarm. This should be an easy fix since First Alarm already makes a battery powered one that works.
Garage Door senors and ability to operate the door through app would be a great addition. I currently use the door sensors on my garage doors to monitor open and close, they are also then monitored when the alarm is armed. The door sensors are not currently designed for this application, but with a small door hinge and some inginuity you can make it work. It would be nice to have a sensor designed for the garage rather than having to make “somethign work” as I did.
