Automating Your Home Lighting with Home Assistant and Raspberry Pico: A Guide to Controlling Your Living Light Based on Light Sensor Data
4 min readMar 27, 2023
In this tutorial, you will learn how to construct a basic light sensor that utilizes Home Assistant and Raspberry Pico Wireless to regulate the living room light based on a specified threshold.
The light will turn off when there is sufficient lighting and turn on when there is insufficient lighting. However, the light will only be activated if there is a continuous period of no adequate light for at least five minutes.
Configure the Hardware Components
We need to have the Raspberry Pico Wireless version and a LDR (light dependent resistor).
To establish a connection for the LDR, attach one end to GP27 (which corresponds to GPIO 27 or ADC1) and connect the other end to a GND (ground) pin.
