# Probe Plus

> Probe Plus is a built-in integration for Home Assistant. It has 44 installs sharing analytics and works locally.

Probe Plus is a built-in Home Assistant integration that reads sensors from a probe device locally. It adds sensors for relay battery and relay voltage. Home Assistant spots the device on its own and offers to add it. During setup in the UI, a probe is selected from the devices found. New devices show up later without setting the integration up again. Nothing extra needs to be installed, since it is built into Home Assistant.
