Custom Component for ESPHome enabling Serial over TCP

This project is forked from the original work at https://github.com/oxan/esphome-stream-server and has been updated to work reliably on ESPHome versions after 2021.10. It has only been tested with ESP32 devices, and support for ESP8266 is not a priority at this time.

Custom component for ESPHome to expose a UART stream over Ethernet. Can be used as a serial-to-ethernet bridge as known from ESPLink or ser2net by using ESPHome.

This component creates a TCP server listening on port 6638 (by default), and relays all data between the connected clients and the serial port. It doesn't support any control sequences, telnet options or RFC 2217, just raw data.

Requires ESPHome v2021.10 or higher.

You can set the UART ID and port to be used under the stream_server component.

uart:
   id: uart_bus
   # add further configuration for the UART here

stream_server:
   uart_id: uart_bus
   port: 6638

You can optionally create a binary_sensor to indicate whether a client is currently connected.

stream_server:
  id: ss

binary_sensor:
  - platform: stream_server
    stream_server: ss
