Architectural overview of intents in Home Assistant
|
||
</p>
|
||
<p>Intents are fired by components that receive them from external sources/services. Conversation, Alexa, API.ai and Snips are currently sourcing intents.</p>
|
||
<p>Any component can handle intents. This makes it very easy for developers to integrate with all voice assistants at once.</p>
|
||
<p>Intents are implemented using the <code class="highlighter-rouge">homeassistant.helpers.intent.Intent</code> class. It contains the following properties:</p>
|
||
