nut VS ocis

> what software do you recommend for gnu/linux to take input from the UPS to tell the laptop to shutdown?

https://networkupstools.org/

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)

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.

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

APC is giving me pre-nut clarity.

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.

I found a way to do this : just copying the data over WebDAV using rclone (https://github.com/owncloud/ocis/blob/b2323752289d31c4844f36ef71a2ba531bd749c2/docs/ocis/guides/migrate-data-rclone.md)

According to the README[1] on their source repository, that is, flatly, untrue.

They say:

> We are very happy that oCIS does not require a Contributor License Agreement (CLA) as it is Apache 2.0 licensed. We hope this will make it easier to contribute code. If you want to get in touch, most of the developers hang out in our rocket chat channel or reach out to the ownCloud central forum.

They also say:

> Some builds of stable ownCloud Infinite Scale releases provided by ownCloud GmbH are subject to an End User License Agreement.

Which seems both reasonable and sensible...

[1](https://github.com/owncloud/ocis/tree/master)

ownCloud recently released version 3 of ownCloud Infinite Scale (OCIS), which is completely rewritten in Go (which means it's fast) and uses micro-services instead of a PHP monolith. It doesn't have any features like mail/calendar/contacts/chat/etc.. yet, just file sync (but that's all I'm looking for).

This feature request (https://github.com/owncloud/ocis/issues/6558) aims to implement mind-mapping functionality in a free Open Source Software similar to Google Drive called ownCloud Inifite Scale (oCIS).
