I own a receiver that only listens to commands via a serial interface (RS232). There’s no IP connection or app to control this device and also infrared is not ideal due to location of Homey. It’s only 4 commands that I need for now and feedback from the receiver to homey is not required.
What options do you see to let Homey control this device? I believe there are some apps that use serial commands over IP (P1 smart meter?).
These are the options that I see:
- Purchase serial to IP converter (like this one). Still Homey needs to be able to send the commands to an IP.
- Get started with arduino and homeyduino. I don’t have any experience with arduino, so this might be too challenging.
