Personalized 🔆Brightness

1. Automate Community
2. Personalization

Inspired by A9-Pie Adaptive Brightness, it's "machine learning" without AI. It generates a customized brightness map based on your preferences in real time, and automatically sets the brightness based on that map and the sensor's output.

This is targeted at devices that have A8 or earlier and/or users who want a lite edition of Adaptive Brightness.

The recommended range for PR is 2 to 512 inclusive. The recommended range for Delay is 0 to 15 inclusive. If you decrease PR, you should decrease Delay. You can play with the parameters until a specific combination is good enough for you.

The precision reducer (PR) is necessary to reduce memory usage, processing, training time, and error margin.

This uses a variant of piecewise-constant interpolation, because linear and spline interpolation require more memory, energy, and blocks.

If you change PR, you should avoid using a backup, because the old map needs to be re-scaled to work with the new PR value. Sorry for inconvenience.
