The Custom Enclosure Factory on AliExpress has some nice cases.

And for a ghetto option, I've got a few old Mentos chewing gum containers around the place :) (This one is stuck to the side of the Central heating unit with magnets.

I think I've found the problem, have submitted a bug report to HomeGenie.

At the moment there is no MySensors v2.0 support in HomeGenie, but I'm working on a new Serial Gateway.

At first there will only be limited support (Switches, Temp, Humidity and Motion) but I'm hoping to have more available within a short time.

The first test version will be available this Friday.

I've started a new thread on the HomeGenie forum with the first test version, you can find the forum here:
