Yellow flag? Yellow lights! Bring the F1 25 game into your smart home

Share your Projects! Custom Integrations

A while back, I was trying to create a Python script to make my Hue lights yellow when F1 25’s UDP output showed there was a yellow flag in the game.

That’s when it dawned on me: Creating a Home Assistant custom integration for the F1 25 game would make this much easier and offer thousands more possibilities! :sparkles:

:racing_car: So here it is:

Open your Home Assistant instance and open a repository inside the Home Assistant Community Store.

Or find it on Github: F1 25 Telemetry for Home Assistant! :checkered_flag:

Now, you can trigger colored smart lights that match flags (or make all lights dramatically turn off when you DNF :grimacing:), create real-time dashboards with tyre wear and lap time data, or make something that I haven’t thought of!

Home Assistant’s amazing graphs can also help you do some nice analysis work after a session.

Here are some of the most important entities:

  • Damage (in general, per part, or when terminal)
  • DRS and ERS
  • Last and Fastest Lap Time
  • Flag (Blue, Yellow, Green, etc.) and Safety Car
  • Fuel Remaining
  • Leader
  • Current Position
  • Weather
  • Session Status
  • Start Lights (if you have 5 smart lights in a row, you can mimic them irl!)
  • Track Temperature
  • Tyre Age, Compound, Temperature and Wear for each tyre

(Note: Some super high frequency sensors are disabled by default to prevent hammering your Home Assistant instance. You can enable them manually, but be careful.)

There’s also a feature that makes Home Assistant re-transmit the raw telemetry packets to another IP/Port, which can be useful if you have an existing dashboard on a phone or steering wheel, and don’t want to enable UDP broadcasting.

Have fun testing, and let me know how you’re using this!
