airalab/sensors-connectivity#1 done , but should we add this package in airapkgs ? @PavelSheremetev @Vourhey @akru

I think it's not a problem to create a nixos service for the package. Enabling/Disabling the service would be as easy as:

services.connectivity.enable = true;

assuming we use default settings. And more advanced usage is

services.connectivity.enable = true;
services.connectivity.config = ''
