Devices the Discord Crew and I have found to be compatible with Home Assistant and ESPHome Bluetooth Proxies
Most of these devices are plug and play auto discovery right into Home Assistant utilizing the Bluetooth or Bluetooth Proxy integration with ESPHome. Need to turn your ESP32 into a BT Proxy? ESP32, ESP32-C3, ESP32 Solo, or use the prebuilt flasher on ESPHome.
A lot of temp/humidity sensors (I use Xiaomi) but the intriguing one is Switchbot Bot which l has the capability of making dumb devices smart.
