Hey everyone! I’m trying to integrate my new projector into my smart home setup, but I’m running into a bit of a snag. The projector doesn’t have a LAN port, which would have made things much easier. Instead, it uses an RS232 interface for control. I have an Ethernet cable available, but no 9-pin connector, so I’m looking for a way to bridge this gap.
I came across a converter that supposedly handles this by taking Telnet commands and forwarding them via serial. It seems like a possible solution, but I’m wondering if there’s a simpler or more reliable method out there. Maybe there’s a way to use MQTT or another protocol to handle the communication more smoothly?
I’ve also heard about using Raspberry Pi or other small computers to act as a middleware, converting Ethernet signals to RS232. Would that be a feasible approach? I’m not very experienced with hardware hacking, so I’m hoping there’s a plug-and-play solution or a software workaround that I can implement without too much hassle.
If anyone has successfully integrated an RS232 device into their smart home setup using Ethernet, I’d love to hear about your experience and any tips or tricks you might have. Whether it’s through a specific converter, custom scripts, or another method entirely, your insights would be invaluable!
Thanks in advance for any help or advice you can offer. I’m really excited to get this working and add another layer of automation to my setup!
