It presents to the host OS as an HID/Keyboard,, but sends no data by
default.  I run it on Linux and use the following FOSS Python program to
read it:

Looking at the Python code, a simple binary packet is sent to the
device and it returns a binary packet with the data.

I can't speak to how it works on anything but Linux.  I've never seen
the TEMPer interfere with anything.
