HA Crash when add integration Koolonova

[sadibisc]

Hello, I have :

• HA Core 2024.9.3 (same problem also found with 2024.9.2 ) on Linux Lite (Virtual Box)
• DSD TECH SH-U11 Converter USB to RS485
• INT 49 enabled on the master thermostat
• Koolnova 100-CPND00 control unit The USB device is shown in Linux command line and HA (with "dmesg | grep USB" I see "FTDI USB Serial Device converter now attached to ttyUSB0"). I installed Koolnova by repository successfully but when I try to add Integration HA, with the indicated parameters (/dev/ttyUSB - 49 or 1 - 9600 - EVEN), it crashed and I have to restart the Virtual Box machine. I tried previosly with another JZK Adapter USB to RS485 adapter with the same result Can you help me ? Thanks Bye Sabino

Hi Sabino, Can you attach some log of your Home Assistant to see what happens ? Did you try to send/receive RS485 commands/infos on your Virtualbox host VM to verify if communication works fine ?

Hi sinseman44, I found the problem, it was not with Home Assistant but with the PC hosting HA. I exported HA to a Raspberry and the integration works well I can close the issue Thanks a lot
