A way to use the M5Stack PoESP32 as a bluetooth-POE adapter with esphome and Homa Assistant, great for bleproxy and madoka thermostats.
- Check DrJohnM61 on how to connect and program the device.
- Flash a blanc ESPHOME firmware or a custom with BLEproxy.
- Connect a u.fl Wifi/BLE antenna.
- Assemble the device and connect to a POE cable.
- Start playing with you new device in Home Assistant.
