+## Optional Features
+NOTE: Your AC has to support these features for it to be used.
+```
+     temp_sensor: This attaches an external temperature sensor to your AC. Gree unfortunately doesnt support a "current temperature" on its own.
+     lights: This switches the backlight of the AC Display on or off
+     xfan: This dries the AC after being used. This is to avoid nasty smells from usage.
+     health: The air goes through a filter to "clean the air".
+     sleep: This will enable a comfortable sleep mode. The AC won't make a lot of noise using this.
+     powersave: It seems this mode should be an efficient way of approximately reaching the desired temperature (temperatures will vary using this).
+     eightdegheat:  This feature maintains the room temperature steadily at 8°C and prevents the room from freezing by activating the heating operation automatically when nobody is at home over a longer period during severe winter
+     air: This feature will extract air from the room. This is to remove hot air or nasty smells from the room.
