Z-wave: new device devolo MT:2656

Hello, sorry for the delayed answer.
I did a reset of the controller Sigma Designs - Controller USB Z-Wave Plus with the zipgateway and raspberry pi.
Also the devices (3 in sum) seems to work with the controller and the zipgateway software.
But I would not say that the controller is for sure 100 % OK. I can be an issue.

So I did the test with the new boot and added the log.
The controller is connected directly over the USB and the local interface of the raspberry.
Maybe you see what is wrong, or what should I try next?

Thank you? BR
Sebastian
