Yes, there's one thing missing.

Nope.

Either of those will work just fine.

In the imon and mce modes, these keys map to the exact same scancode. You
have the imon keytable loaded, but an mce remote. So these keys work, but
the rest do not.

For example, the packets that correspond to ENTER contain a 0x28, but the lircd.conf value for ENTER is 0x1C. I wonder why this does not work for the iMON mini. How do you decode/map these to lircd.conf entries?

The imon-decoded values map to KEY_FOO names, which are all defined in
include/linux/input.h, and have corresponding values that are passed
along via the input device, and are what lircd then maps.

The missing piece is loading the matching RC-6 keymap, but it seems that
was failing for you. I'll have to see if I can get to the bottom of that
with some of my own imon hardware, I've not tried it of late. This should
be the only thing that needs doing to make your setup behave correctly.

Well, that or I push another build that introduces the modprobe option
back to just load the mce keytable by default... Upstream objects to the
change, as the plan in the long run is to move all keytables out to
userspace, auto-loaded by udev triggers.
