As yet only on paper. I plan to get a UPS with a NUT (Network UPS Tools) interface, connect it with the HA NUT integration, and write an automation to shut down when battery level is low.
That should be good idea and ideal way to go. Since this setup is for my friend who wants to keep the cost lower, he went with the normal APC ups without any NUT features.

I use the following automation setup for managing my UPS in my rack that handles all the primary gear that is connected to it. The actions at 10% charge left are actioned through hass.agent’s MQTT commands to the client installed on the main PC and NAS is set to safe shutoff on its own once the press action is activated and everything to power on when power is restored.
I have a seperate automation setup to notify me when my HA instance has restarted and use a switchbot bot to turn on and off the usb port that my skyconnect is plugged into on my mbeat 7 port hub which I also got rid of the battery from and swapped in a cr2 battery eliminator cable so I don’t have to worry about new batteries when I am not home should I need to control it.
I have smart plugs as well set to on state on power restore as well as backup for core devices to act as a auto power switch for the restore on power loss setting to work more consistently as a failsafe.
