Control your WS2812B LED strip over WiFi with ESPHome!
The cost of the entire build is low (about 5€) and the controller can drive WS2812B led strips of any length.
The firmware is built with ESPHome, so the controller can be easily integrated in Home Assistant; a lot of LED effects are also supported.
The capacitive touch button on the top allows you to control the LED strip like a normal (non smart) device. With a long press of the button the brightness can be increased or decreased.
