Github Klausmu Esp32 Fan Controller Esp32 Fan Controller 51 Off This project describes how to use an esp32 microcontroller for controlling a 4 pin fan (pwm controlled fan). main features are: mode 1 (fan mode or pwm mode): directly setting fan speed via pwm signal. mode 2 (climate mode or temperature controller mode): fan speed automatically increases if temperature is getting close to or higher than target.

Github Klausmu Esp32 Fan Controller Esp32 Fan Controller 51 Off Fan1, fan2 offset, fan heater, fan filter. modified static code for curve points, min, max, to listen to cmd topics for the settings. created discovery messages to add these to home assistant, through number component. i created a different mode for fan filter, this is added under fan component, so i can be set in speed like a fan. relais:. The esp32 fan controller will automatically be integrated into your home assistant installation via mqtt discovery. thanks a lot for the contribution from s4saken and niklas . if you are interested, here is the discovery message for the climate, please also see here . The esp32 is powered with 3.3v and the i o pins are not 5v tolerant. normally a 4 wire fan would expect a 5v pwm signal, but in my tests the 3.3v from the esp32 were always enough. if it is not enough for your fan, you could use a level shifter, please see here. Learn how to use esp32 to control fan. how to program for esp32 to turn fan on off. the detail instruction, code, wiring diagram, video tutorial, line by line code explanation are provided to help you quickly get started with esp32. find this and other esp32 tutorials on esp32io .
