Sonoff basic DIY dimmer

[lordzid]

This video prompted me to such a homemade product.
Since I have a task for illuminating a barbecue and, in general, now there is an option to make lighting along the contour of the gazebo, I remembered about the basic and the ability to screw a PWM module to it (sold by kilograms for a ridiculous price).

PWM module

The characteristics of the module allow you to connect a tape with a wide range of power supply.
I connected a 12V tape.

We find a diode on the BASIC board and cut off the diode. We need one contact (see photo)

Sonoff basic

We collect everything according to the scheme (I’m not an artist, but I hope everything is clear)

The code … here’s my favorite ESPHOME and the Home Assistant integration.

Made buttons to quickly switch to a given percentage (100, 80, 60 and 40).
The buttons for turning on the tape and the relay turn on and off each other, so that the power supply remains without load and only the BASIC is powered.
