NUT looks like quite active based on their website. Microupsd daemon handles also some switches and leds for the end user, I mean user can press some switch on the device and daemon will perform an action described in configuration file, so porting everything to NUT would take more time that I actually got for this. Thank You all. I will try to write some simple binary, place it in /lib/systemd/system-shutdown/ and test it.
