Im looking to get a UPS for my nuc running haasio just to be able to shut it down safely in the event of a power cut.
Is it only the APC units that will integrate with hassio or will other manufactures integrate providing they have a USB of ethernet port.
I don’t need anything too powerful, any recommendations please.
Look at NUT sensor
Any ups supported basically
I’m using an APC UPS with NUT to shutdown 4 computers. Home Assistant isn’t even part of the equation.
I’ve been considering this… with a NUC, you get a 12v input don’t you? must open up a lot more options. Essentially you could almost run it like a laptop.
I don’t use a NUC right now though, I use a mini-ITX setup. Although it can run from a 12v PSU with an adapter anyway.
Here’s one I found, there’s only a status light no plug but its a start:

One could easily attach anything they wanted to the LED pin, such as an ESP98266, but I’ll keep looking for a solution that offers a built-in status.
You have a point there mitchins, there’s a lot of energy wasted converting a 12 volt battery to mains power only to convert back to 12v again.
I didn’t know about Nut tmjpugh, I was looking at the APCUPSd integration, thanks for that.
To clarify, the NUT integration isn’t required to have the UPS shutdown one or more computers. As I mentioned, my instance of Home Assistant doesn’t use the NUT integration, but NUT is used to shutdown 4 computers (including the one hosting Home Assistant).
What the integration offers is visibility into the UPS’s status (battery voltage, is the UPS currently running from the battery or the mains, battery runtime, etc). You can create automations to monitor one or more status parameters and do something in the event the UPS switches to using its battery, or battery life drops below a threshold, or whatever. I currently don’t need any of that so my instance runs without the use of the NUT integration.
I use APCUPSd to monitor a CyberPower UPS. When power fails, an HA automation shuts down the HA host after 2 minutes.
@123 is correct
Best to do shutdown on PC. This is more reliable and cleaner as you must do configurations on PC anyway
HA NUT sensor is best used for status notification
What model of Cyberpower UPS do you use it with?
1500PFCLCD connected by USB cable to the NUC.
How did you install the UPS NIS server on the NUC? did you install it directly to the OS or did you use a Docker container?
Do you have a good set of instructions?
I tried getting this running previously but I could never get my UPS to communicate with the server. I think I tried to run NUT thru docker tho.
The add-on is integrated into Hass.io installations. Nothing but annotating the configuration.yaml file to recognize the UPS device and create the sensors. Real simple.
Ah, I didn’t know you were using hassio. Thanks for the info.
Hi everyone. I was looking for those informations, so thanks. Maybe something could be clarified, and would be useful for the community :
NUT is firstly a project, external to HA : https://networkupstools.org/
You can find here the UPS manufacturers that are compatible : https://networkupstools.org/stable-hcl.html Huuuuuuuuuuuuuge list !
Then, NUT is also an HA integration, which is discussed above : https://www.home-assistant.io/integrations/nut/
Am I right ?
