Create (templateable) cameras that display qr codes in homeassistant

Last update: Oct 06, 2022

Overview

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};;"

Following is configurable:

Name	Description	Required	Type	Default
`name`	The name of the Camera	Yes	String	-
`content`	The content that shall be encoded (can be template)	Yes	Template	-
`version`	The "Version" of the qr code (which is basically the size)	No	int between 1 and 40	Auto
`error_correction`	How much error correction the QRCode should have	No	see Error Corretion	ERROR_CORRECT_M
`box_size`	The size of the Black Boxes in pixel	No	Positive Integer	10
`border`	Border arround the code	No	Integer > 3	4
`fill_color`	RGB Color for the (normaly black) parts of the QRCode	No	String of form "r,g,b"	"0,0,0"
`back_color`	RGB Color for the background of the QRCode	No	String of form "r,g,b"	"255,255,255"
`edge_color`	RGB Color for the edge of the qr code (only used if color_mask is radial or square)	No	String of form "r,b,g"	"0,0,0"
`left_color`	RGB Color for the left side of the qr code (only used if color_mask is horizontal or vertical)	No	String of form "r,g,b"	"0,0,0"
`right_color`	RGB Color for the right side of the qr code (only used if color_mask is horizontal or vertical)	No	String of form "r,g,b"	"0,0,0"
`color_mask`	Mask for the Colors of the QR Code	No	See Color Mask	"solid"
`drawer`	Options on how to render the QR Code	No	See Rendering	"square"

Error Correction

The error_correction parameter controls the error correction used for the QR Code.

Name	Discription
ERROR_CORRECT_L	About 7% or less errors can be corrected.
ERROR_CORRECT_M	About 15% or less errors can be corrected.
ERROR_CORRECT_Q	About 25% or less errors can be corrected.
ERROR_CORRECT_H	About 30% or less errors can be corrected.

Color Mask

Name	Number in Image
`solid`	1
`radial`	2
`square`	3
`horizontal`	4
`vertical`	5
(WIP)	6

Rendering

Name	Number in Image
`square`	1
`gapped_square`	2
`circle`	3
`rounded`	4
`vertical_bars`	5
`horizontal_bars`	6

Most of this Project is based on the qrcode module for python

Describe the bug

On startup of Home Assistant the following warning appears in the log:

2022-06-02 13:42:59 WARNING (SyncWorker_2) [homeassistant.helpers.service] Unable to find services.yaml for the qrcam integration

As suggested here https://github.com/home-assistant/core/issues/23197 the way to fix this is to add an empty services.yaml file.

v1.0.0.10-hotfix(Apr 3, 2022)

This should fix #3. There are major flaws in the python-qrcode package and it does not seem like the developer is active anymore. I think that they have a dependency on pillow which is not bound to a version. This caused many problems. I will have to look into that in more detail. But generation of qr codes with only fill and back color should work fine.
