HWDB key mappings and eventlircd evmap override

I’m using an Ugoos UR02 remote and found the suggested hwdb file to remap keys.

However some key variables seem not to work when used in the hwdb file which result in using alternate names (f1,f2,f3,…)

Why is this not possible? See i.e. list of keynames: https://kodi.wiki/view/List_of_keynames

Also, some keys are not recognized when I check the Kodi logs (no sym value)

In the lines in the log like below, some keys have the correct value between brackets for the sym attribute and others don’t.

Keyboard: scancode: 0x49, sym: 0x118, unicode: 0x00, modifier: 0x0

Because of this I thought I’d try using eventlircd to map the bluetooth remote to lirc.

I can’t get the 98-eventlircd.rules and evmap files in .storage to overwrite the existing system included files. Where do I need to place these files to use my own versions?

I tried putting the udev rule in udev.d.rules folder and creating a separate evmap and eventlircd.d folder.

There is very little information to be found.
