I’ve been struggling with getting my Z-Wave controller to stay online consistently on my Raspberry Pi 4 running OpenHabian. After a fresh install and configuring everything properly, the controller keeps going offline, which is frustrating. I’ve tried adjusting the serial port settings, checking permissions, and even switching to different Java options, but nothing seems to solve the issue. I’m wondering if there’s a specific firmware version required for the Razberry2 module or if there’s a configuration step I might have missed. Any advice or pointers would be greatly appreciated!
