Frequently asked
Quick answers.
How do I get started? +
Open the app at app.led.fyi and sign in with a free account. Drag out a wall, pick a panel from the library, and the engine does the topology and load math as you go.
Can I import my old projects? +
Yes. led.fyi v2 imports projects from the original blinkingthings / v1 simulator. Open the file from the File menu and it converts in place.
Does it work offline? +
The web app keeps working once it has loaded, and the desktop app runs fully offline — designed for the job site and locations with no connection.
How is my data handled? +
Projects you don’t save to the cloud stay on your device. See the Privacy page for exactly what we collect and how it’s protected.
I found a bug — what do I do? +
Email support@led.fyi with what you were doing and, if you can, the project file. The more detail the faster we can reproduce and fix it.
