ESP8266 Community Forum

I have recently discovered an openhab binding to epson projectorswhich gave me the understanding i can do a lot more through RS232 port than the irda.
So currently looking for a solution if ESP8266 can be connected to the RS232 port on the projector so it can pass all the serial communications vis tcp|ip which will be binded in ubuntu to a com port for control by openhab.

Connecting the ESP should not be a problem, all you need is a RS232 tranceiver such as the MAX3232. Most devices do not use hardware flow control, so connecting the RX/TX pins will suffice in most cases.
On the software side a combination of esp-link and socat should do the trick.
