[Blueprint] Presence detection using Door, Wi-Fi SSID and GPS

Blueprints Exchange

Hello, it’s My first blueprint but I thought it might be useful to others.

This blueprint allows you to detect whether someone has entered or left home using a combination of:

• Door sensor trigger

• Wi-Fi SSID (via Companion App)

• GPS device tracker

It’s useful for reliable presence detection, especially where GPS isn’t enough (e.g., apartment buildings or poor signal areas).

Features

• Detects entry or exit based on Wi-Fi and GPS change

• Sends mobile notifications

• (Optional) Logs key data to Logbook

• Works with Home Assistant Companion App (Android/iOS)

Required Inputs

Field Description
Person Name Used in logs and notification messages (e.g., John)
Door Sensor Triggers the automation (binary_sensor, door class)
Wi-Fi SSID Sensor Provided by Companion App (sensor.*_ssid)
GPS Tracker device_tracker.* entity (Companion App)
Home SSID Name Your actual Wi-Fi name, e.g., HomeNetwork_5G
Notification Service Notify target, e.g., notify.mobile_app_johns_iphone
Enable Logbook (Optional) Toggle logging of presence tracking

How it works

  1. When the door opens, it stores current SSID & GPS state.

  2. It sends location request and updates.

  3. Over ~15 minutes, it checks if either SSID or GPS changed:

• SSID home → not home → Exit

• SSID not home → home → Entry

• GPS home → not_home → Exit

• GPS not_home → home → Entry

  1. When detected, it:

• Sends notification

• (Optionally) Logs to Logbook

• Stops automation to avoid repeat triggers

Example Notifications

• John has left home (Wi-Fi)

• John has arrived home (GPS)

• 3 minutes before door opened – SSID: true, GPS: home

• Automation completed

Requirements

• Home Assistant Companion App

• Door sensor (binary_sensor, device_class: door)

• SSID and GPS sensors (Companion App)

• Mobile notify service
