Breaking out my old Pi 1b. Anything lightweight I can put it to work on?
A couple of different project ideas/software over here as well: https://hub.balena.io/

Serendipity Engineering - part 1
The idea was to provide the balenistas with nothing more than an SD card and a postcard printed with a QR code. The code would lead them to an open fleet on balenaHub which they could then join by flashing the SD card and popping it into a device they already had. The instructions on the fleet card in hub told them to open http://cattlegrid.local on a browser, which opened a web server now running on their RaspberryPi device. Here's how it looked:

Use Raspberry Pi as Airplay server to screen mirror on TVs, monitors, projectors
There is a very similar level of magic for converting a raspberry pi to do AirPrint

Tell HN: Laptop Runs Without Battery
> what software do you recommend for gnu/linux to take input from the UPS to tell the laptop to shutdown?
https://networkupstools.org/
- Network Ups Tools

UPS - USB not recognized
The Synology software is based on N.U.T. https://networkupstools.org and the Plus 1100 (listed on NUT as the Easy Power 1200) is supported in the native package with the 'blazer' driver. If you have the skills, I would SSH into the NAS and see if the device is 'noticed' or better yet recognised by the USB sub-system when you plug it it. (Normal Linux would use the lsusb command to see devices but I have no NAS handy to see if this is valid on the Synology)

What UPS are you using?
Others have answered the hardware part of your question. I have not seen much mention about the software to control graceful shutdowns. For this I suggest you look at the ”Network UPS Tool” (NUT for short) project (https://networkupstools.org/). It is mostly manufacturer agnostic with clients for a vast array of hardware components.

You're looking for NUT.

APC Smart Connect
Network UPS Tools is one option: https://networkupstools.org/

PSA: APC has updated it's terms for the PowerChute management software. It now requires a licence
APC is giving me pre-nut clarity.

Cyberpower UPS issue
So no, the NAS does not monitor the battery level. The UPS does that. The NAS just acts on the messages it receives from the UPS via Synology's version of NUT - Network UPS Tools (https://networkupstools.org/). The NAS will first receive the ON_BATTERY/POWERFAIL signal. Then, eventually the BATTERY_LOW signal at which time the UPS will shutdown. So you really need to set a time for it to shut down *BEFORE* you get BATTERY_LOW.
