Question 1

How do I set up OnAirScreen with Home Assistant?

Accepted Answer

Enable MQTT in OnAirScreen settings, and it automatically publishes device configurations for switches, sensors, and text entities via MQTT autodiscovery. Ensure your Home Assistant instance has MQTT configured to receive these entities seamlessly.

Question 2

OnAirScreen vs hardware on-air lamps: which is better?

Accepted Answer

OnAirScreen offers more flexibility with customization, remote control, and cost savings, but hardware lamps provide physical durability and zero software dependency. Choose based on your need for digital integration versus simplicity.

Question 3

Can I control OnAirScreen from my phone?

Accepted Answer

Yes, but only through the web UI accessed via a browser, as there's no dedicated mobile app. The web UI supports real-time updates and dark mode, but the experience may vary on smaller screens.

Question 4

How to customize labels and colors in OnAirScreen?

Accepted Answer

Use the settings dialog or remote commands like CONF:LED1:text=FOO and CONF:LED1:activebgcolor=COLOR. The README provides UDP and HTTP examples for dynamic configuration changes.

Question 5

What are the system requirements for Raspberry Pi?

Accepted Answer

OnAirScreen runs on Raspberry Pi with a ready-to-run SD card image available from the developer's shop. It's optimized for low-cost hardware, but performance may depend on the Pi model and display resolution.

Question 6

Why are my UDP commands not working in OnAirScreen?

Accepted Answer

Check if UDP port 3310 is open and not blocked by firewalls. Use the CONF:Network:udpport command to adjust settings, and ensure commands match the format in the README, like LED1:ON.

Question 7

Is OnAirScreen free for commercial use?

Accepted Answer

The source code is open-source, but precompiled binaries are sold commercially. For commercial deployments, consider licensing or self-compiling from source, as noted in the donation section for support.
