To create an automation, navigate to Configuration and then Automations in Home Assistant. Click the “Add Automation” button and choose a name for your automation.
Under the “Trigger” section, select “Voice Command” as the trigger type. Here, you can define the exact phrase that will activate the automation.
Think carefully about the phrases you use to trigger your automations. Choose phrases that are easy to remember and pronounce, and that are unlikely to be confused with other commands.
Consider using natural language when defining your voice commands. For example, instead of saying “Turn on Living Room Lights,” you could say “Turn on the lights in the living room.”
You can also use synonyms and variations of your voice commands to make your automations more flexible. For example, you could define both “Turn on the lights” and “Switch on the lights” to trigger the same action.
When naming your automations, use descriptive names that clearly indicate the purpose of the automation. This will make it easier to manage and troubleshoot your automations in the future.
Test your automations thoroughly after creating them to ensure they are working as expected. This will help you to identify and fix any issues before they become a problem.
Defining Actions and Conditions
After defining the trigger, you need to specify the actions that will be performed when the voice command is recognized. Under the “Actions” section, you can add multiple actions to be executed in sequence.
Actions can include turning on/off devices, adjusting the thermostat, playing music, or sending notifications. You can also add conditions to your automations to make them more context-aware.
For example, you might want an automation to only turn on the lights if it’s after sunset. Conditions can be based on time, day, device state, or any other available data in Home Assistant.
This allows you to create intelligent automations that adapt to your specific needs and preferences. Save the automation, and it will be active immediately.
When defining actions, consider the order in which they are executed. The order can be important for achieving the desired outcome, especially when dealing with multiple devices or services.
Use conditions to create automations that are more context-aware and responsive to your environment. This can help to prevent unintended actions and make your smart home more intelligent.

Don’t be afraid to experiment with different actions and conditions to create automations that are truly personalized and useful for your daily life.
Example Automation: “Goodnight” Routine
Let’s create an example automation for a “Goodnight” routine. This routine will turn off all the lights, lock the doors, and set the thermostat to a comfortable sleeping temperature when you say “Goodnight.”
First, create a new automation and name it “Goodnight Routine.” Set the trigger to “Voice Command” and enter the phrase “Goodnight.”
| Action | Device/Service | Parameters |
|---|---|---|
| Turn off | All lights | (Select all lights) |
| Lock | Front door lock | (Lock action) |
| Set thermostat | Thermostat | Temperature: 68°F |
| Play music | Bedroom speaker | Stop |
Next, add the actions: turn off all lights, lock the front door, and set the thermostat to 68°F. You can also add an action to stop any music playing in the bedroom.
This “Goodnight” routine is a great example of how you can automate multiple tasks with a single voice command. It simplifies your bedtime routine and makes your home more secure and comfortable.
Consider adding additional actions to your “Goodnight” routine based on your specific needs and preferences. For example, you could add an action to turn on a night light or set an alarm for the next morning.
You can also add conditions to your “Goodnight” routine to make it more context-aware. For example, you could add a condition to only lock the doors if they are currently unlocked.
Experiment with different actions and conditions to create a “Goodnight” routine that is perfectly tailored to your lifestyle.
Remember to test your “Goodnight” routine thoroughly to ensure it is working as expected. This will help you to identify and fix any issues before you rely on it for your daily routine.
Defining Custom Voice Commands
Home Assistant allows you to define custom voice commands using natural language processing (NLP). This enables you to create more intuitive and personalized voice interactions.
By leveraging NLP, you can use more natural language when speaking to your voice assistant, rather than relying on rigid and specific phrases.
To define custom voice commands, you’ll need to use the “Sentences” integration in Home Assistant. This integration allows you to define a set of sentences that Home Assistant will recognize and map to specific actions.
You’ll create a `sentences.yaml` file in your Home Assistant configuration directory. This file will contain the sentences and their corresponding actions.
Using custom voice commands allows for a more natural and conversational interaction with your smart home. You are no longer limited to pre-defined phrases, making the experience more user-friendly.
The “Sentences” integration provides a flexible way to define your own vocabulary and grammar for voice control. This allows you to create voice commands that are tailored to your specific needs and preferences.
By using NLP, Home Assistant can understand the intent behind your voice commands, even if you don’t use the exact same phrase every time. This makes the voice control experience more robust and reliable.
The `sentences.yaml` file is a central repository for all your custom voice commands. This makes it easy to manage and maintain your voice control system.
Remember to back up your `sentences.yaml` file regularly to prevent data loss. This will ensure that you can easily restore your custom voice commands if something goes wrong.
Configuring the Sentences.yaml File
In the `sentences.yaml` file, you’ll define each custom voice command along with the actions to be performed. The structure of the file is straightforward, using YAML syntax.
Here’s an example of a custom voice command to adjust the living room lights: “`yaml language: “en” sentences: – “turn on the living room lights” – “switch on the living room lights” – “lights on in the living room” action: service: light.turn_on entityid: light.livingroom_lights “`
This example defines three different ways to say the same command: “turn on the living room lights,” “switch on the living room lights,” and “lights on in the living room.” All three phrases will trigger the same action: turning on the `light.livingroomlights` entity.
You can define multiple sentences for each command to provide flexibility in how you speak to your voice assistant. After creating or modifying the `sentences.yaml` file, you’ll need to restart Home Assistant for the changes to take effect.
Pay close attention to the indentation in your `sentences.yaml` file. YAML is sensitive to indentation, so incorrect indentation can cause errors.
Use a text editor that supports YAML syntax highlighting to make it easier to read and edit your `sentences.yaml` file. This will help you to identify and fix any syntax errors.
You can use variables in your custom voice commands to make them more dynamic and flexible. For example, you can use a variable to specify the brightness level of a light.
Test your custom voice commands thoroughly after adding them to your `sentences.yaml` file. This will help you to identify and fix any issues before you rely on them for your daily routine.
Consider using comments in your `sentences.yaml` file to document your custom voice commands. This will make it easier to understand and maintain your voice control system in the future.
