ESP01 D1 mini Motion sensor + photoresistor + grid of led +

Flash the esp-D1-mini to install Tasmota

Flash Tasmota using a Chrome based browser for ESP82XX and ESP32

GPIO on a ESP-D1-mini

Configuration of MQTT

Info

To find the MQTT settings, you can go to the MQTT configure on Homeassitant

Change : Host, User, Passwd and topic parameters.

A new entity is automatically added to the MQTT list of entities already found (+1 in the number of entities)

Add the LED grid - WS2812

See: tasmota.github.io/docs/Lights/

Add a single led

Add the Photoresistor

See: tasmota.github.io/docs/ADC/

The change in the photoresistor value is unfortunately not sent automatically with each change. You must therefore define a rule directly in Tasmota. See : PIR-Motion-Sensors documentation

Automation

Turns ON the LED grid if movement is detected and there is not enough light

Turns OFF the LED grid if the "detected" state changes to "not detected"
