+The gas sensor of the BME68X must be calibrated. This differs from the BME280, which does not require any calibration.
 There is a range of additional information for this, which the driver also provides. These values can be found in HomeAssistant under Diagnostics.

+## Compilation
+
+To enable, compile with `BME68X` in `custom_usermods` (e.g. in `platformio_override.ini`)
+
+Example:
+
+```[env:esp32_mySpecial]
+extends = env:esp32dev
+custom_usermods = ${env:esp32dev.custom_usermods} BME68X
+```
+
 ## Revision History
+
 ### Version 1.0.0
+
 - First version of the BME68X_v user module
+
 ### Version 1.0.1
+
 - Rebased to WELD Version 0.15
 - Reworked some default settings
 - A problem with the default settings has been fixed
 
+### Version 1.0.2
+
+* Rebased to WELD Version 0.16
+* Fixed: Solved compilation problems related to some macro naming interferences.
+
 ## Known problems
+
 - MQTT goes online at device start. Shortly afterwards it goes offline and takes quite a while until it goes online again. The problem does not come from this user module, but from the WLED core.
 - If you save the settings often, WLED can get stuck.
 - If many LEDS are connected to WLED, reading the sensor can cause a small but noticeable hang. The "Pause While WLED Active" option was introduced as a workaround.

+# Update Brightness Follow Sun
+
+This UserMod can set brightness by mapping [minimum-maximum-minimum] from [sunrise-suntop-sunset], I use this UserMod to adjust the brightness of my plant growth light (pwm led), and I think it will make my plants happy.
+
+This UserMod will adjust brightness from sunrise to sunset, reaching maximum brightness at the zenith of the sun. It can also maintain the lowest brightness within 0-6 hours before sunrise and after sunset according to the settings.
+
+## Installation
+
+define `USERMOD_BRIGHTNESS_FOLLOW_SUN` e.g. `#define USERMOD_BRIGHTNESS_FOLLOW_SUN` in my_config.h
+
+or add `-D USERMOD_BRIGHTNESS_FOLLOW_SUN` to `build_flags` in platformio_override.ini
+
+
+### Options
+Open Usermod Settings in WLED to change settings:
+
+`Enable` - When checked `Enable`, turn on the `Brightness Follow Sun` Usermod, which will automatically turn on the lights, adjust the brightness, and turn off the lights. If you need to completely turn off the lights, please unchecked `Enable`.
+
+`Update Interval Sec` - The unit is seconds, and the brightness will be automatically refreshed according to the set parameters.
+
+`Min Brightness` - set brightness by map of min-max-min : sunrise-suntop-sunset
+
+`Max Brightness` - It needs to be set to a value greater than `Min Brightness`, otherwise it will always remain at `Min Brightness`.
+
+`Relax Hour` - The unit is in hours, with an effective range of 0-6. According to the settings, maintain the lowest brightness for 0-6 hours before sunrise and after sunset.
