Happy to help! For me, python was the way to get everything I wanted, instead of almost what I needed. In my opinion, the python-evdev documentation is really helpful, and should be able to get you most of the way to what you need. For what it’s worth, based on my experience with AutoHotKey on Windows, you should be able to recreate anything you had before and more with python.
I went on a journey to do something very similar, I remap keypad buttons to various other inputs using a python script running as a service. My original post is here, and my eventual solution is in the comments. My post has some links to other solutions that I tried, but ultimately I’m happy using a custom python script. That may not fit your need, but maybe it will help a little!
The Guardian references an NPR article where they discuss the vulnerability as a phishing attack, so it doesn’t seem to be anything interesting after all.

I’ve been running three of these for about the same length of time - two things surprised me, but both are documented in their manual. First, the working temperature is -9.9℃-60℃/14℉-140℉, so if you plan to use one in an environment colder than ~10℃, the readout will flatline. Second, they use a CR2450 battery, which is a little more difficult to find where I live than a CR2032.
Neither of these are criticisms, just things I wish I had noticed sooner.
