# Ness Alarm

> Ness Alarm is a built-in integration for Home Assistant. It has 48 installs sharing analytics and works locally.

Ness Alarm is a built-in integration that connects Home Assistant to a Ness alarm panel. It communicates locally with the panel and is set up in the UI using the panel's host and port. It provides alarm control panels and binary sensors. An option can infer the arming state from zone activity, and another option shows or hides the arm home mode on the alarm panel. Two actions are included: one changes the state of an aux output, and the other triggers a panic alarm.
