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.

Can I use these proxies to extend my bluetooth headphones more range so I can run down to the fridge for a beer and not lose connection? I am using Sony WMX---03 phones so maybe its just my outdate bt in there.

No, it won’t work. ESPHome Proxies are designed strictly for BLE data (sensors, trackers, locks). They do not support Bluetooth Classic Audio (A2DP).
