I have tested latest release 2.14.00 Dyna where support for Wiser devices is mentioned in the release notes. There should be support for LK Fuga battery push button (see here + here) and Wiser double relay output.
I am using Conbee II USB stick with firmware 0x26720700.
The result of my test is:
The 4 button Wiser LK Fuga cannot be adopted in Phoscon.
The double relay switch appear as lights and these are working. However, there is no button events registered on the created switch device. This means usage of the push buttons cannot be detected. I have verified this using the Deconz restapi - see picture.
