I’ve been diving into the world of ESP32 integration with Home Assistant, and it’s been an exciting journey! I currently have a HA server running on a Raspberry Pi, and I’ve successfully configured an ESP32 board to act as a BLE tracker. This setup allows me to connect devices like my Xiaomi thermometer sensor via BLE to the ESP32 and then to the HA server—everything works seamlessly so far!
However, I’ve been pondering whether it’s possible to connect a second ESP32 board to the first one via BLE and have it appear in Home Assistant as if it were connected via WiFi. Essentially, I’m wondering if the first ESP32 can act as a BLE hub, enabling the second ESP32 to communicate with HA exclusively through BLE. This would be a fantastic way to extend my setup without relying on additional WiFi connections!
I’d love to hear if anyone has experience with this kind of configuration or has any insights or suggestions. Maybe there’s a way to use existing HA features or integrations to achieve this? I’m eager to explore and learn more about the possibilities here. Thanks in advance for any guidance or ideas you might have!
