MQTT Camera Instructions on how to use an MQTT image message as a Camera within Home Assistant.
Camera
0.43 Configurable mqtt

The mqtt camera platform allows you to integrate the content of an image file sent through MQTT into Home Assistant as a camera. Every time a message under the topic in the configuration is received, the image displayed in Home Assistant will also be updated. Messages received on topic should contain the full contents of an image file, for example, a JPEG image, without any additional encoding or metadata.

This can be used with an application or a service capable of sending images through MQTT.

Configuration

To enable this camera in your installation, add the following to your {% term "configuration.yaml" %} file:

# Example configuration.yaml entry
mqtt:
  - camera:
      topic: zanzito/shared_locations/my-device

The sample configuration above can be tested by publishing an image to the topic from the console:

mosquitto_pub -h <mqtt_broker> -t zanzito/shared_locations/my-device -f <camera_imaga.jpg>
