Hey everyone, I wanted to share my recent success with getting the Somfy URTSI II Binding working over RS-485. This was a bit of a puzzle at first, but I managed to crack it!
Initially, I was a bit confused because the documentation only mentioned RS-232 support. But I had a feeling RS-485 could work since it’s more scalable for multiple devices. I decided to give it a try without any major hardware changes.
To my delight, it worked perfectly! The RS-485 bus allowed me to connect up to 16 URTSI II devices, which is exactly what I needed for my setup. I did notice that the device address is hardcoded to 1, which is fine for RS-232 but could be more flexible for RS-485. However, this didn’t affect my current setup, so I’m not too concerned about it.
I think this information would be helpful for others who might be considering RS-485 for their Somfy devices. Maybe I should submit a pull request to update the documentation. What do you guys think?
This experience just goes to show how much potential these devices have when you dig a little deeper. I’m really happy with how everything is working now, and I can’t wait to explore more possibilities with my smart home setup!
If anyone has questions or wants to share their own experiences with Somfy devices, feel free to reach out. Let’s keep the knowledge flowing!
