I’ve always been passionate about integrating all my home devices into a seamless smart ecosystem, and recently, I achieved a milestone by successfully connecting my Vizio SmartCast TV to Home Assistant. This journey wasn’t without its bumps, but the result has been absolutely worth it!
Initially, I was a bit overwhelmed because I couldn’t find any official API documentation for the Vizio SmartCast TV. After some research, I stumbled upon a GitHub repository that provided the necessary API details. This discovery was a game-changer, and I couldn’t wait to dive in.
I decided to use Node-RED for the integration since it’s flexible and well-supported within Home Assistant. The process involved setting up a command line switch in my configuration.yaml file. I configured it to send HTTP requests to the TV’s IP address, controlling power and volume. Here’s a snippet of my setup:
yaml
- platform: command_line
switches:
living_room_tv:
friendly_name: TV
command_on: ‘/usr/bin/curl -k -H “Content-Type: application/json” -H “AUTH: xxxx” -X PUT -d ‘{“KEYLIST”: [{“CODESET”: 11,“CODE”: 1,“ACTION”:“KEYPRESS”}]}’ https://TV_IP_ADDRESS:9000/key_command/’
command_off: ‘/usr/bin/curl -k -H “Content-Type: application/json” -H “AUTH: xxxx” -X PUT -d ‘{“KEYLIST”: [{“CODESET”: 11,“CODE”: 0,“ACTION”:“KEYPRESS”}]}’ https://TV_IP_ADDRESS:9000/key_command/’
One challenge I faced was generating the correct authentication token. The GitHub documentation was a bit vague on this, so I had to experiment a bit. I discovered that the token could be extracted during the pairing process, which involved a series of curl commands to simulate the pairing steps.
Once everything was set up, I tested the integration thoroughly. It was incredibly satisfying to see my TV respond to commands from Home Assistant. I even created a custom card in my Lovelace dashboard to control the TV, making it seamlessly integrated with my other smart devices.
This project taught me the importance of perseverance and the value of community-driven solutions. I’m now looking forward to exploring more integrations and enhancing my smart home setup further. A huge thank you to the GitHub contributor who made this possible and to the Home Assistant community for their continuous support!
If anyone has questions or needs help with their own TV integration, feel free to reach out. I’m happy to share what I’ve learned!
