SimpliSafe Smart Alarm System

Quick verdict

SimpliSafe is designed for people who just want a working alarm system without any tinkering. It delivers on that promise well. But from a smart home perspective, it's a dead end for local control - the Home Assistant integration is cloud-only (it can arm/disarm and read sensors, but nothing is local), and everything is proprietary. A good alarm, but a poor smart home citizen.

Standout: The easiest home alarm to set up - designed for people who don't want to think about home security technology.
