4 years ago I don't have one of these devices to test against, but...
The tell tale statement in the doc is this:
• Radio: 433.92MHz ISM short range receive only
This usually means it uses the OOK protocol, and the learning is done on the switch itself. I'm not sure what role the two buttons play in pairing - it is possible you pair them individually, although I can't ascertain if that is the case from the user guide. If you have a hand-remote, you could check if you can independently pair the left and right buttons to different buttons on the hand remote.
Original Mihome OOK devices used to have 2 memory locations for pairing, looks like they may have upgraded this to 3.
Note that the range on the Raspberry Pi radio is significantly worse than the official mihome gateway, due to the various grounding, casework and aerial differences that are out of control of Energenie at the Pi end.
Also, putting the light switch inside a metal earthed box(!) will have an effect on radio range, and if the Pi is geographically behind the switch instead of in front of it, you effectively have an earthed cage in the way, and only a reflected signal will make it into the switch (presumably via the front plastic plate).
I suspect it is more a reduced radio performance issue than anything else.
Look at the aerial hack picture in this ticket on May 2nd, and try that and see if it helps.

Also, you don't say if you have other devices that DO work with this library. Do you have a faulty radio?

Anyone know of any reason why the MIHO009/MIHO071/etc Double Light Switches are not working with this? Are they operating on a different encoding? The manual for the Double Light Switches https://energenie4u.co.uk/res/pdfs/MIHO009-User-Guide-v1.0.pdf seems to be missing infomation on the radio when compaired to the Single Light Switches https://energenie4u.co.uk/res/pdfs/MIHome-Light-User-Guide-v1.5.pdf
