As an enthusiastic user of smart home technology, I’ve recently delved into the ESP32-S3-Box3, a device that promises a wealth of possibilities for home automation. The journey has been both exciting and challenging, and I’d like to share some insights and tips that might help others navigate this device.
The ESP32-S3-Box3 comes packed with sensors and components, including a radar for presence detection, an IR controller, and temperature and humidity sensors. My initial goal was to integrate these features seamlessly into my Home Assistant setup. While the hardware is impressive, the configuration process required some careful tweaking.
One of the first hurdles I encountered was configuring the display backlight. After some research and experimentation, I found that setting the backlight to GPIO47 resolved the issue. Here’s a snippet of the configuration that worked for me:
yaml
platform: ledc
pin: GPIO47
id: lcd_backlight_pin
light:
- platform: monochromatic
output: lcd_backlight_pin
id: lcd_backlight
name: “LCD Backlight”
restore_mode: ALWAYS_ON
This configuration ensures the backlight remains on, providing consistent visibility. However, getting the display itself to show anything has been a bit tricky, but I’m optimistic that it’s just a matter of refining the text configuration.
The I2C configuration was another area that demanded attention. By setting the SDA to GPIO41 and SCL to GPIO40, I was able to connect the temperature and humidity sensor, an AHT-30. While this sensor isn’t yet supported by ESPHome, I’m hopeful that future updates will include compatibility.
For those looking to integrate the IR emitter/receiver and radar sensor, the schematics indicate that these components utilize GPIO40 and GPIO41. This means careful planning is essential to avoid conflicts and ensure all features function as intended.
In summary, the ESP32-S3-Box3 is a versatile device with immense potential. While the setup process requires some trial and error, the rewards of a fully integrated smart home system make it well worth the effort. I’m excited to continue exploring this device and look forward to sharing more insights as I progress.
If anyone has tips or experiences to share regarding the ESP32-S3-Box3, I’d love to hear them! Let’s collaborate to unlock the full potential of this remarkable device.
