On Air Meeting Trigger

ON-AIR Meeting Trigger helps you automatically signal when you are in an online meeting.

It detects when you have a Google Meet, Microsoft Teams, or Zoom meeting open in your browser and sends simple ON / OFF signals to endpoints you configure on your local network.

This is ideal for:
- “ON AIR” lights or LED signs
- Home Assistant automations
- Smart relays (Tasmota, Shelly, ESP devices)
- Custom local webhooks or scripts
No cloud services are required. Everything runs locally in your browser.

How it works
1. The extension monitors your open browser tabs for supported meeting services:
- Google Meet
- Microsoft Teams
- Zoom
- Custom service ( your Web URLs here )

2. When a meeting tab is detected:
- ON state is triggered

3. When no meeting tabs remain:
- OFF state is triggered

4. Each state change triggers one or more Targets that you configure
Detection can be configured to:
- trigger when any matching meeting tab exists
- or only when the meeting tab is active

Targets (outputs)
You can configure multiple outputs at the same time.

Home Assistant integration

The extension works well with Home Assistant using the REST API.

Common use cases:
- Toggle an input_boolean when a meeting starts or ends
- Trigger automations that control lights, relays, or notifications
- Drive an “ON AIR” indicator anywhere in your home
Authentication is handled using a Long-Lived Access Token provided by the user.
