Bluetooth over ethernet with POE esp board

A developer named Heppu built an ESP32-POE-based Bluetooth-over-Ethernet bridge to eliminate latency in remote gaming setups, using an optical HDMI connection and a Claude subscription to solve Steam Link's input lag. The project, available at esp-hci-bridge, provides remote Bluetooth controller inputs that feel identical to local connections, and the developer plans to extend it to Home Assistant to replace ESPHome setups with remote Bluetooth adapters.

I got sick of steam link’s latency and had some left over hardware and claude subscription at hand to solve this. With optical hdmi and poe esp board I managed to get fully working remote gaming setup from my rack to living room. The controller inputs feel exactly the same as it feels next to the machine with mb’s bt adapter. Here’s the site: esp-hci-bridge and git repo: GitHub - heppu/esp-hci-bridge: ESP32-POE as a remote Bluetooth controller over Ethernet, Zig firmware logic and host daemon · GitHub

I’m planning to use this with also with my homeassistant server to get rid of esp home setup and have plane remote bt adapters.
