Quick verdict
If your house has wired alarm sensors from a previous security system, the Konnected Alarm Panel Pro is the way to bring them into Home Assistant. It replaces your old alarm panel brain with an ESPHome board that exposes every zone as a sensor in HA. Setup requires comfort with basic wiring, but the result is a fully local alarm system with no monthly monitoring fees. Not for beginners, but incredibly powerful for the right use case.
Standout: Retrofit existing wired alarm sensors into Home Assistant via ESPHome with no cloud and no monitoring fees.
