Brightness Detection and Auto-Brightness

Please see a module that samples images from a webcam to calculate the ambient brightness of the light in the room, sends a matching notification with the light level in percentage, while also (optionally) sends a notification to the MMM-RemoteControl to adjust the brightness of the screen accordingly (using that module’s brightness range of 10-200).

The module samples one image every predefined interval (defaults to 1 minute), and currently supports (and tested over) USB Webcams, while I plan to add support for the PI camera module, which I do not currently have handy, but soon.

Hope you’d like it. It was born because the mirror was too bright for me at night, or too dim in the daylight, and I wanted to create auto-brightness.

I’d appreciate your tests and comments!

Thank you!

UPDATE: Now supporting the PI camera, as well as configuring which camera to use, if not the default

MMM-BlinkCameraIntegration

Interfaces with the Blink home security cameras, displays snapshots and latest videos on the Magic Mirror.

https://github.com/eric-h-st/MMM-BlinkCameraIntegration

Next to be added:

• Support periodic snapshots from the cameras
• Support configuration of cameras and hubs

(Screenshot won’t upload for some odd reason…)

UPDATE:
Now supporting displaying and animating brightness changes at the top of the screen.

@Eric_H said in MMM-AmbientBrightnessDetection:

Next to be added:

• Configurable factor to be added to the brightness level sent to MMM-RemoteControl, to make the brightness range more visible in extreme light/dark cases.

• CEC support to change the actual brightness of the monitor, if supported.

• PI camera module support

** Now also supported: **

• Configurable factor to be added to the brightness level sent to MMM-RemoteControl, to make the brightness range more visible in extreme light/dark cases.

Thank you @sdetweil .

• I control the brightness by sending a notification to the MMM-RemoteControl module (code already written and working, no reason to re-invent), found here.
• Since the brightness is set programmatic ally via css in that module, I’m not sure how various monitors would react, but I tested on three here, including the one behind the mirror, and they seem to work quite the same.
• I’m taking a single shot once every configurable interval, with a default of 60 seconds.

Hope I answered all of your questions.

Thank you!

@BKeyport Thank you

Same here.
@MichMich this started after I updated my Raspbian to the latest, and now getting this error that I cannot resolve:
