+## Dimmer Switches as On/Off Switches
+> ### [Feit Dimmers](https://www.amazon.com/gp/product/B07SXDFH38/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1)
+> I tried to find an on/off switch that looked/felt like the Feit dimmers but didn't find anything so I decided to use the Feit dimmers.
+
+> #### Fans
+> I created a custom [tuya_dimmer_as_binary_fan_output.h](./custom/tuya_dimmer_as_binary_fan_output.h) component that prevents the dimmer from being dimmed (always changes it right back to 100%) and can report the change in on/off status back to a fan component.
