QRCam

Deprecated. Use this

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};;"

Following is configurable:
