EvoHome (HGI80) not working after domoticz restart

[bramv]

I have Domoticz (newest beta) running on a Raspbery pi 4 with a HGI80 to control my EvoHome system.

When I restart Domoticz the EvoHome (HGI80) does not work any more.
In the logging the following error apears:

Oct 7 12:16:16 RaspberryPi4 domoticz: evohome serial: Opening serial port: /dev/serial/by-id/usb-Texas_Instruments_TUSB3410_Boot_Device_TUSB3410-if00-port0@115200
Oct 7 12:16:16 RaspberryPi4 domoticz: evohome serial: Error opening serial port: /dev/serial/by-id/usb-Texas_Instruments_TUSB3410_Boot_Device_TUSB3410-if00-port0
Oct 7 12:16:17 RaspberryPi4 domoticz: evohome serial: serial setup retry in 30 seconds...

After I reboot the Raspberry pi it works again.

Does the terminate or close hardware function need a close serial port or something like that.
