QRCam
This custom component creates cameras displaying qrcodes. The QRCodes can be static or generated from templates. If you use a template as content the camera will update with a new qr code when the template updates.
This component will set up the following platforms.
| Platform | Description |
|---|---|
qrcam |
Display QRCodes in Camera entites. |
Installation
Configuration
Example configuration.yaml entry:
camera:
- platform: qrcam
name: "Test Camera"
content: "Hello World"
another a bit more complicated example using a template:
camera:
- platform: qrcam
name: "Test Camera 2"
content: "{{states('input_boolean.karl')}}"
fill_color: "0,255,0"
back_color: "0,0,0"
displaying a wifi qr code (replace {SSID} and {PASSWORD}):
camera:
- platform: qrcam
name: "WIFI"
content: "WIFI:S:{SSID};T:WPA;P:{PASSWORD};;"
