Home Assistantist and Siri integration

If you already have Apple HomeKit devices in your home, you don’t need to replace them to start using Home Assistant.

You can bring many of your existing HomeKit-certified devices directly into Home Assistant using the HomeKit Devices integration. Once added, they behave like any other native Home Assistant device—ready for dashboards, automations, helpers, and advanced logic.

Understanding the Integration Names

In Home Assistant, you’ll see two similarly named integrations:

  • HomeKit Bridge → Exposes Home Assistant devices to Apple Home
  • HomeKit Devices → Brings Apple HomeKit devices into Home Assistant

If your goal is to use a HomeKit device inside Home Assistant, you want:

HomeKit Devices

What Devices Can You Add?

Many HomeKit-certified devices can be paired directly, including:

  • Lights and switches
  • Smart plugs
  • Thermostats
  • Fans
  • Motion and contact sensors
  • Locks
  • Garage door openers

If the device supports local HomeKit pairing, it will usually work.

Step 1: Remove the Device from Apple Home (If Needed)

If your device is already paired to Apple Home, you’ll need to:

  1. Remove it from the Apple Home app
  2. Factory reset the device

HomeKit devices can only be paired to one controller at a time. Resetting puts the device back into pairing mode.

Step 2: Add “HomeKit Devices” in Home Assistant

  1. Go to Settings
  2. Select Devices & Services
  3. Click Add Integration
  4. Choose HomeKit Devices
  5. Select your device when it appears
  6. Enter the HomeKit setup code (found on the device or packaging)

Once paired, the device becomes a fully native entity inside Home Assistant.

Use It Like Any Other Device

After pairing, your HomeKit device works like any other Home Assistant device:

  • Add it to dashboards
  • Use it in automations
  • Combine it with Zigbee, Z-Wave, or Wi-Fi devices
  • Trigger helpers or advanced logic
  • Include it in scripts and scenes

At this point, it’s no longer “just a HomeKit device”—it’s part of your broader smart home system.

Why Bring HomeKit Devices Into Home Assistant?

More Powerful Automations

Home Assistant allows complex logic that goes beyond basic HomeKit automations:

  • Multi-condition triggers
  • Presence-based logic
  • Helper-based state tracking
  • Advanced timing and conditions

You get more control without replacing your hardware.

Cross-Platform Flexibility

Once in Home Assistant, your former HomeKit device can:

  • Work with Alexa
  • Work with Google Assistant
  • Be exposed back to Apple Home via HomeKit Bridge
  • Integrate with non-Apple ecosystems

You’re no longer locked into a single platform.

Local Control and Reliability

Many HomeKit devices communicate locally over your network.

When paired through HomeKit Devices:

  • Commands are fast
  • Automations continue working without internet
  • You reduce reliance on external cloud services

That’s a big reliability win.

Using Siri with This Setup

If you want Siri control and Home Assistant automation power:

  1. Pair the device to Home Assistant using HomeKit Devices
  2. Enable HomeKit Bridge in Home Assistant
  3. Expose that device back to Apple Home

Now:

  • Home Assistant becomes the central brain
  • Apple Home becomes the interface
  • Siri controls the device through Home Assistant

This setup gives you the best of both worlds.

Things to Keep in Mind

  • Some devices require manufacturer hubs
  • Not every HomeKit device supports direct pairing
  • Resetting devices may interrupt existing automations
  • It’s best to migrate devices one at a time

Final Thoughts

If you’ve invested in Apple HomeKit devices, moving to Home Assistant doesn’t mean starting over.

With the HomeKit Devices integration, you can adopt your existing hardware into a more flexible, powerful automation system—while still keeping the option to use Siri and Apple Home.

It’s a smart way to expand your setup without replacing what already works.
