Hi all, I have updated both my HomeAssistant installations with OS 17.2 this morning. After rebooting, they both show: “Driver: failed to open the serial port. error: no such file or directory, cannot open /dev/serial/by-id/…” in the ZWave JS UI App. No hardware changes. I do not even see the U…

Have a look at my post here…issue with OS 17.2 on some Pi4 devices…is resolved now in linked thread… [image] Home Assistant OS 17.2 and ZWave JS UI Home Assistant OS This seems to be the issue on GitHub dealing with (and resolving) this problem on certain versions of Pi4 …

cant confirm. both Zigbee (ZHA) and Zwave (Zwave JS) operating correctly after 17.2 was updated. not running a RPI4 so maybe there’s a lead? did you check the OS GitHub repo and file an issue with logs there? they can help

Running usb z-wave on Rpi5 and working with OS17.2

I will try to log in an issue in the GitHub repo tomorrow.

Thanks for the thread. I experienced the same and rolled back to 17.1. I’m on a RPi4 with a Nortek HUSBZB-1 stick.
