🔧 Best Presence Detector for Home Assistant 🔧

In today’s blog post, we’ll guide you through the installation process of presence detection using the LD2410 sensor, an affordable and highly sensitive sensor capable of detecting even the tiniest movements. This sensor is natively supported in Home Assistant and can be easily integrated with ESP32 and ESPHome. The best part? No soldering is required! Let’s dive in!

Choosing ESP32 Over Bluetooth

When considering the integration options, I decided to go with ESP32 instead of Bluetooth. During testing, I experienced frequent disconnections and stability issues with the Bluetooth integration, as many others have also reported online. On the other hand, my ESP32 setup has been impressively stable for weeks, providing a reliable solution.
