This looks like a possible combination to have Home Assistant send information to a IP and Port set up with ser2net
TCP Sensor - https://home-assistant.io/components/sensor.tcp/
Ser2net - https://sourceforge.net/projects/ser2net/
ser2net is a tool that i would like to send a payload to on a remote PI (in another room) so it can be passed on to a HDMI matrix device via a USB serial / RS232 connection I have . (Potentially usable for any serial based media device you want to connect to)
Is anyone using this already , or have any idea how it would work ?
The blurb with the TCP Sensor is that it " allows the integration of some services for which a specific Home Assistant component does not exist. If the service communicates over a TCP socket with a simple request/reply mechanism then the chances are that this component will allow integration with it.
