Introduction to Presence Detection in Home Assistant
Smart environments respond to your movements like an invisible butler. They adjust settings based on where you are—without buttons or voice commands. This capability stems from location awareness systems that interpret device connections and movement patterns.
Zone-based systems create virtual boundaries around physical spaces. When your smartphone enters a designated area, connected routines activate. For example, your air conditioner might lower the temperature as you approach your neighborhood.
Two primary methods power these responsive systems. Mobile apps share GPS coordinates, while network sensors monitor device connections. Combining both approaches reduces errors caused by temporary signal drops or delayed location updates.
Implementing this technology streamlines daily routines. Lights illuminate when needed, and security systems arm themselves automatically. These adjustments conserve energy and personalize your living space through context-aware behavior.
Core Concepts of Presence Detection
Modern living spaces become smarter when they adapt to human patterns. At the heart of this adaptability lies a system that identifies whether occupants are physically present. Let’s break down how this works and why Wi-Fi plays a key role.
What Is Presence Detection?
Presence detection determines if specific gadgets—like smartphones or sensors—are active on your network. When your phone connects to Wi-Fi, the system marks you as “home.” Disconnections trigger departure actions. This method uses real-time data from device trackers, which monitor network activity to update statuses.
Benefits of Using Wi-Fi Devices for Tracking
Wi-Fi-enabled gadgets offer distinct advantages over other methods. They’re already part of most households, require no extra hardware, and provide instant updates. Here’s how they compare:
| Method | Accuracy | Cost | Setup Complexity |
|---|---|---|---|
| Wi-Fi Tracking | High (room-level) | $0 (uses existing devices) | Low |
| GPS Tracking | Moderate (zone-based) | Free (mobile apps) | Medium |
| Bluetooth Beacons | Very High | $20+ per sensor | High |
Combining Wi-Fi with other methods reduces errors. For example, pairing network data with mobile app signals creates reliable room-level tracking automations. This approach minimizes false triggers caused by temporary disconnections.
Device tracker entities in smart systems act as digital fingerprints. They store connection histories and trigger rules based on patterns. When integrated with automations, they adjust lighting, climate, and security without manual input—making your space truly responsive.
Preparing Your Home Assistant Environment
A well-prepared foundation transforms basic automation into intelligent responsiveness. Before implementing location-based triggers, ensure your system meets technical requirements and connectivity standards.

Remote Access and Mobile App Setup
Install the official mobile application from your device’s store. During installation:
- Grant location permissions “Always”
- Enable background refresh in app settings
- Pair with your instance using QR code
Configure sensors under Settings > Devices & Services. Activate Wi-Fi scanning and motion detection toggles. Test connectivity by triggering manual updates through the app’s notification panel.
Setting Up Mobile Device Tracking
Your smartphone holds the key to smarter automations. By configuring it as a tracking device, you unlock location-aware adjustments that respond to your movements. The process centers on the Home Assistant Companion app—your gateway to seamless integration.
Enabling Location Tracking on Your Mobile
Start by installing the Companion app from your device’s store. During setup:
- Allow “Always” access to location services
- Enable background refresh in system settings
- Scan the QR code to link your instance
These permissions let the app share real-time data with your system. A device tracker entity automatically appears in your dashboard, updating whenever your phone connects or disconnects from networks.
To confirm it’s working, open the app’s notification panel. Tap Send Sensor Update—your location should reflect within seconds.
“Test tracking during different activities: stationary, moving, and switching networks”
advises a community expert.
Fine-tune responsiveness under Settings > Sensors. Adjust update intervals from 1-15 minutes based on battery preferences. Pair this with Wi-Fi triggers later for layered accuracy.
Implementing home assistant presence detection with Wi‑Fi Devices
Transform your existing network into a responsive system through precise configuration. This section walks through creating template sensors that translate Wi-Fi signals into actionable data. You’ll establish rules that interpret device connections as occupancy states.
Configuration Steps and Key Settings
Start by editing your configuration.yaml file. Add these lines to create a template sensor:
binary_sensor:
- platform: template
sensors:
phone_home:
value_template: "{{ is_state('device_tracker.iphone', 'home') }}"
friendly_name: "Phone Home Status"
This code checks if your phone’s device tracker shows “home” status. Replace iphone with your device’s entity ID from the dashboard. Save changes and restart your system to activate the sensor.
Adjust these settings for better results:
- Set update intervals to 30 seconds for real-time accuracy
- Combine multiple device trackers using OR conditions
- Enable entity history to review connection patterns
“Always test sensors individually before combining them in automations”
Your system now interprets connected as “home” and disconnected as “away.” Create automations using these states under Settings > Automations. Pair Wi-Fi data with motion sensors later to reduce false triggers during brief network drops.
Utilizing Wi-Fi Network Names (SSID) for Accurate Detection
Your network’s unique identifier becomes a powerful tool for precise location tracking. By monitoring which Wi-Fi name (SSID) devices connect to, you gain room-level awareness without extra hardware. This method reduces errors caused by temporary signal drops or overlapping zones.
Enabling the Wi-Fi Connection Sensor
Start by activating SSID reporting in the mobile app:
- Open the Companion app’s Settings
- Navigate to Sensors > Wi-Fi Connection
- Toggle “Report Network Name” to enabled
This creates a new sensor showing your device’s current SSID. Test it by moving between different networks. The state updates instantly when switching connections.
Creating Template Sensors for Device Tracking
Transform SSID data into actionable triggers using this code:
template:
- sensor:
name: "Living_Room_Presence"
state: >
{% if is_state('sensor.phone_ssid', 'Main_Floor') %}
Occupied
{% else %}
Vacant
{% endif %}
| Tracking Method | Accuracy | Setup Time |
|---|---|---|
| SSID Monitoring | Room-Level | 5 Minutes |
| IP Address Tracking | Building-Level | 15 Minutes |
| GPS Geofencing | Street-Level | 30 Minutes |
Set automation conditions using your SSID sensor states. For example, trigger lights when the living room sensor changes to “Occupied.” Combine multiple template sensors across floors for whole-house coverage.
Combining GPS and Wi‑Fi for Enhanced Accuracy
Merging location technologies creates a safety net against automation mishaps. Standalone tracking methods sometimes misinterpret brief disconnections or delayed updates. Blending GPS coordinates with network signals filters out these errors.
Integrating Multiple Data Sources
GPS excels at outdoor positioning but struggles indoors. Wi-Fi tracking works well inside buildings but can’t detect approaching users. When combined, they fill each other’s gaps. Your system checks both sources before triggering actions.
| Method | Error Rate | Response Time | Setup Complexity |
|---|---|---|---|
| GPS Only | 12-18% | 2-4 minutes | Medium |
| Wi-Fi Only | 8-10% | 10-30 seconds | Low |
| Combined | <3% | 15-90 seconds | Medium |
Set conditions that require both signals to agree. For example, lights turn off only when:
- GPS shows you’re 500+ feet away
- Wi-Fi disconnection lasts 5+ minutes
“After combining methods, my false triggers dropped from weekly to once a year,” reports a Reddit user in r/homeautomation.
Time delays prevent rushed decisions. Add 2-3 minute buffers before activating departure routines. This accounts for brief network drops while grabbing mail or taking out trash.
Test your setup by simulating common scenarios. Walk around the block while monitoring automation states. Adjust time thresholds until the system works seamlessly with your daily patterns.
Advanced Automations for Home and Device Management
Elevate your smart system from basic timers to intelligent routines that adapt to your lifestyle. By leveraging real-time status data, you can craft rules that respond to patterns rather than fixed schedules. This approach reduces manual adjustments while maintaining precise control over your environment.
Triggering Actions Based on Presence State
Create responsive rules using device status changes as activation points. When a smartphone disconnects from your network for five minutes, it could initiate a “leaving” sequence. Combine multiple triggers for reliability—like requiring both Wi-Fi disconnection and motion sensor inactivity before shutting down systems.
Use this YAML template to manage office lighting:
automation:
- alias: "Office Lights Automation"
trigger:
platform: state
entity_id: binary_sensor.office_occupied
to: "off"
action:
service: light.turn_off
target:
area_id: office
Examples of Practical Home Automations
Implement these time-saving routines:
- Activate security cameras when all residents disconnect from Wi-Fi
- Send phone alerts if motion sensors trigger during “away” mode
- Adjust thermostat settings based on active device count
| Automation Type | Trigger Condition | Resulting Action |
|---|---|---|
| Energy Saver | No devices connected for 30 mins | Lower HVAC output by 50% |
| Security | Unexpected motion during vacancy | Flash lights & send SMS alerts |
| Comfort | First device reconnects | Brew coffee & open blinds |
“Layered conditions eliminated my phantom triggers—now lights only turn off when I’m truly gone,” notes a Home Assistant forum contributor.
Test each sequence under different scenarios. Gradually increase complexity by adding delay timers or requirement thresholds. This ensures your setup remains efficient without becoming overly sensitive to temporary status changes.
Integrating ESPresense and BLE for Room‑Level Tracking
Take your automation precision to the next level by pinpointing movements within individual rooms. ESPresense combines Bluetooth Low Energy (BLE) signals with affordable hardware to create detailed occupancy maps. This approach lets you trigger room-specific actions, like turning on bedside lamps when entering a bedroom.
Installing and Configuring ESPresense on ESP32
Start with an ESP32 board ($6-$10) and a USB cable. Follow these steps:
- Download the ESPresense firmware from GitHub
- Connect your device to a computer
- Flash using ESPHome-Flasher tool
After installation, access the ESP32’s web interface through its IP address. Name each unit based on its location—like “Living_Room_Tracker”—and set broadcast intervals to 2 seconds for real-time updates.
MQTT Integration and Device Tracking
Connect ESPresense to your MQTT broker for centralized data handling. Modify these settings in the web interface:
- Broker address: Your Home Assistant IP
- Port: 1883 (default)
- Topic: espresense/devices
Create template sensors in your configuration file to interpret BLE signal strength. For example, track two family members simultaneously by assigning unique device MAC addresses. When a person enters the kitchen, their smartphone’s BLE signals trigger coffee maker activations.
“My setup distinguishes between upstairs and downstairs movements with 98% accuracy,” shares a DIY smart home enthusiast.
Test your configuration by walking through rooms while monitoring MQTT messages. Adjust signal thresholds to prevent overlapping room detections. This sensor-driven method eliminates guesswork, ensuring lights and appliances activate only where needed.
Conclusion
Creating an intelligent living space starts with reliable automation foundations. By blending Wi-Fi tracking with complementary methods like GPS and BLE, you achieve precise control over your systems. Detailed configuration ensures lights, climate, and security respond accurately to real-time patterns.
Double-check settings during setup to avoid common pitfalls. Verify network names, update intervals, and sensor thresholds match your house layout. Cross-referencing multiple data sources reduces errors caused by temporary disconnections or signal interference.
Following this guide helps maintain default stability while customizing automations. Make sure to test scenarios like brief exits or overlapping device connections. Review entity histories periodically to fine-tune responsiveness without compromising energy efficiency.
With proper implementation, your house becomes a coordinated ecosystem that adapts to daily rhythms. Keep documentation handy for future upgrades—clear information management prevents configuration conflicts. Start small, validate each step, and watch your automated environment evolve seamlessly.
