Module QR Code

QR Code

Module type: qr_code · Category: Content · Pro

Generate QR codes from URL, plain text, template output, or entity state.

Sources

Source	Use
URL	Encode a static URL.
Text	Encode arbitrary text.
Template	Encode the result of a Jinja2 template (live updates).
Entity	Encode the current state of an entity.

Customization

• Size (px)
• Foreground / background colors
• Error correction level — L / M / Q / H
• Logo overlay (optional)
• Margin / quiet zone

Examples

• Wi-Fi access — encode WIFI:T:WPA;S:GuestNetwork;P:guestpass;;
• HA mobile login — template encoding a long-lived token URL (be careful with secrets!)
• Dynamic ticket — template combining entity attributes
• Door access — encode a rotating code based on input_text.access_code

Tips

• Template-driven QR codes update live, but scanning while it's animating can be flaky — use static codes for things people will scan.
• For Wi-Fi sharing, use HA's QR helper integrations or hard-code via Text source.
• Larger codes encode more data but are harder to scan — keep payload tight.
