Hi @blackchart,
Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).
@Daniel-RUIZ9
I may have found a solution to my problem, I have to test a few days to be sure.
Hard my domoticz installation I have two raspberry one in server the second in client.
The raspberry server is connected to the USB gateway and on the second I have configured the ethernet gateway.
I keep you informed if I still have crashes.
