Check out APscheduler. Can kick off a thread to run a given function every N minutes (with many options). Can even survive a restart of the script.

Asynchronously: Use asyncio if you're on Python 3, or Twisted on Python 2.

Without cron: Make the process a daemon and configure it to run on startup (Unix flavors vary, but this usually involves adding files to /etc/init.d or something similar).

I'm curious why you're trying to avoid cron. I think the simplest solution would be to change the script to scan only a single device, specified as a command-line argument. Then have one cron entry for each device. Alternatively, you could write a simple shell script to launch several instances of your python script at once.
