I just picked up a 4K commercial display to upgrade my TV for cheap. It has an RS232C port on the back for control, and Home Assistant has a native integration to control it via a local Linux tty. The hitch is that my Home Assistant server is located in a spot not near the television, and running physical serial line to it would be inconvenient. But, since I have a Raspberry Pi connected as the streaming media box, I should be able to plug a USB adapter into it and route the serial data over the network, right?

Is there a a good way to do this in HAOS?

    That’s what they’re saying - you can use an ESP32 device as a serial proxy without having to do anything special. If you already have a device attached to it you could use the socket:/… syntax below.

    Per the integration documentation:

    Port

    The serial port the TV is connected to. This can be a local device path or a remote serial proxy URL. For example, /dev/ttyUSB0 (USB adapter), socket://192.168.1.100:2000(network proxy), or socket://esphome-device.local:6638 (ESPHome).

      Oh, nice, thanks!

      (Oddly, the documentation that came up when I looked didn’t mention the socket options.)
