What you need before you start
Before you set up anything, you should make sure you have a few things ready. Home Assistant should already be running on your device. It can run on a small computer, a server, or any machine that can keep the app open each day. You should also have a Stream Deck connected to your computer. It can be a basic one or a bigger one. All of them work fine for this task.
Your computer must have the Stream Deck app installed. This is the main app that lets you add buttons and change the layout. Once you can see your Stream Deck inside the app, you are ready to move to the next part.
How To Setup Home Assistant on the Elgato Stream Deck
How to install the required plugin
The Stream Deck does not connect to Home Assistant by default. You need a plugin that acts as a bridge between the two.
Start by opening the Stream Deck app. On the right side, click the store icon to open the plugin marketplace. Once it loads, search for Home Assistant. You will see a plugin designed specifically for this purpose. Click install. This adds new Home Assistant actions to your Stream Deck.
At this point, the plugin is installed, but it is not yet connected to your Home Assistant system. You still need to link the two.
How to connect Stream Deck to Home Assistant
Home Assistant uses long lived access tokens to allow external apps to send commands securely. Think of this token as a key that gives the Stream Deck permission to control your smart home.
Open Home Assistant in your browser and click your profile picture in the bottom left corner. Scroll down to the section labeled long lived access tokens. Create a new token and copy it immediately. You will not be able to view it again, so make sure it is saved somewhere safe.
Next, return to the Stream Deck app. Drag a Home Assistant action onto any button. In the settings panel on the right, you will see fields for your Home Assistant address and the access token. Paste the token into the token field and enter your Home Assistant URL. This will usually look like:
If a test button is available, use it to confirm the connection. If everything is set up correctly, the plugin will successfully connect to Home Assistant.
