Add the compile-time option `-D USERMOD_SSDR` to your `platformio.ini` (or `platformio_override.ini`) or use `#define USERMOD_SSDR` in `my_config.h`.

For the auto brightness option, the usermod SN_Photoresistor has to be installed as well. See SN_Photoresistor/readme.md for instructions.

### auto-brightness-min / auto-brightness-max
The lux value calculated from usermod SN_Photoresistor will be mapped to the values defined here.
The lux value calculated from usermod SN_Photoresistor or BH1750_V2 will be mapped to the values defined here.
The mapping, 0 - 1000 lux, will be mapped to auto-brightness-min and auto-brightness-max

WLED current protection will override the calculated value if it is too high.
