New scalable, fault-tolerant, and efficient open-source MQTT broker
Shameless plug since i'm a contributor but VerneMQ [1] is a pretty programmable one. You have options from using webhooks to writting your plugins in Lua or Erlang/Elixir.

All right, which one of you did this?
I do know a real world use for Erlang (it also surprised me when i investigated about it), but two of the biggest mqtt brokers are coded in erlang: emqx, vernemq

Mosquitto: An open-source MQTT broker
The VerneMQ bugtracker scares me. Especially this one: https://github.com/vernemq/vernemq/issues/1663. I'm running one instance but I'm on the lookout for an alternative that can more reliably save messages if a subscription client goes down.

It took almost a full day, but I finally got a decent homelab diagram :D Feedback is most welcome!

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?

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.
