Integrating Google Home with OpenHAB for Seamless Automation

Hello everyone,

I’ve been exploring ways to integrate my Google Home ecosystem with OpenHAB to create a more seamless and automated smart home experience. One of the challenges I’ve encountered is controlling my TV, which is connected to a Google Chromecast. I wanted to automate the process of turning on the TV and setting it to the last-used mode when I arrive home, without manually interacting with my phone or the Google Home app.

My Setup

I’m using the latest OpenHABian version on a Raspberry Pi 3B. My TV is powered off when I’m away, and I want it to turn on automatically when I come home. The TV should start in the last-used mode, which is typically the TV input rather than Chromecast. I’ve set up a scene in Google Home that does exactly this, but I wanted to trigger it directly from OpenHAB.

The Solution

After some research and experimentation, I found that I could use the Google Home Actions binding in OpenHAB to send commands to my Google Home device. This binding allows me to trigger scenes and routines that I’ve set up in the Google Home app. Here’s how I did it:

  1. Install the Google Home Actions Binding

    • Go to the Paper UI in OpenHAB.
    • Navigate to Configuration > Add-ons > Bindings.
    • Search for “Google Home Actions” and install it.

  2. Set Up the Google Home Device in OpenHAB

    • After installing the binding, add your Google Home device to OpenHAB.
    • Make sure your Google account is linked properly.

  3. Create a Rule in OpenHAB

    • I created a rule that triggers when I arrive home (using a geofence or a smart sensor).
    • The rule sends a command to my Google Home device to execute the “Start TV” scene.

Here’s a snippet of the rule I created:

java
rule “Start TV when arriving home”
when
Item Presence_Arrived changed to ON
then
sendCommand(GoogleHome_Device, “execute scene Start TV”)
end

  1. Testing the Integration
    • I tested the integration by simulating my arrival home and watched as the TV powered on and switched to the correct input.
    • It works seamlessly, and I no longer need to manually interact with my phone or the Google Home app.

Benefits of This Integration

  • Convenience: The TV starts automatically when I arrive, saving me time.
  • Energy Efficiency: The TV stays off when I’m away, reducing standby power consumption.
  • Customization: I can modify the scene in Google Home to suit my preferences, such as setting the volume or changing the input source.

Conclusion

Integrating Google Home with OpenHAB has been a game-changer for my smart home setup. It allows me to leverage the powerful automation capabilities of OpenHAB while still benefiting from the seamless integration and user-friendly interface of Google Home. If you’re looking to automate your TV or other devices, I highly recommend exploring the Google Home Actions binding in OpenHAB.
