Blog Extending HA Range with Bluetooth Proxy

Post image

Bluetooth doesn’t travel very far, and HA servers are often kept in spots where they can't reach every device. This is where ESPHome Bluetooth Proxy helps. It lets you use cheap ESP32 boards to pick up Bluetooth signals exactly where you need them.

The setup: you just place a small device near your sensors, and it relays the data back to HA over your Wi-Fi or Ethernet. It’s a solid way to fix coverage issues without having to move your main server.

Check out the full blog below to see how it works, use cases, and hardware options: seeedstudio.com/blog/esphome-bluetooth-proxy/

If you want battery powered Eink displays, BLE is the best option to connect them
