There is no option in Homegenie to read or set configuration variables on Fibaro flood sensor FGFS-101 when operating in 12V DC. Then I investigated a little bit more and narrowed the cause of the bug.
Fibaro flood sensor FGFS-101 has two operational modes, 12V DC and battery powered. According to which mode is used, device reports different supported classes. Interestingly, when sensor is operated on battery I can see supported class "Configuration", while this class is not visible when device is on 12V DC. Then I said, OK, it's the problem of the device itself, not Homegenie. But then I tried the same with HomeSeer and the result are different then in HomeGenie. There still are different supported classes for both modes, but "Configuration" is present in both modes. So I concluded that HomeGenie somehow wrongly reads supported classes. It's probably bug.
I also attached screenshots of both modes for Homegenie and also from Homeseer.
