UPS / Battery Backup

Hi,
has anyone ever installed a NUT client on the Octopi to shut it down in a controlled manner in case of power failure?

sudo apt-get install nut-client

My setup is the following:

Raspberry Pi 3 B+ with PoE HAT (so power supply via PoE).
APS UPS
Synology NAS (as NUT server)
