It doesn’t appear that either repo is working colindunn/hassio-addons or hassio-addons/addon-nut (or just isn’t visible in the add on store).
Any thoughts on how to install?
I installed colindunn’s repo last week. Its working fine for me.
You need to add the repo before it will show it the store:
@hijinx, I have installed it in the past, but isn’t available and is erroring.
Am I missing something?
The repo owner needs to update the config.json to add:
"arch": [
"aarch64",
"amd64",
"armv7",
"i386"
],
This is mandatory for hassio addons now.
I had the same error. It was solved by powercycling the UPS.
Sadly I dont have a fork of this repo. Maybe someone else forked it?
I do have the addon installed and running (x86 only)… is there any way to reverse engineer a repo?
Alternatively we can hope/pray/beg that the hassio community addon that is in beta will will progressed…
Maybe there is hope? 
I noticed that the nut repo has the original developers email address so I contacted them to see if I can get the addon code (dockerfile, config json etc). 
i have same problem add-on can’t find the USB cable attached to the RPi how i solve it ?
I have similar problem with my CyberPower UT850EG. The add-on can never find it after I connect the device or reboot the host, but when I try to restart the add-on after a day or two everything starts to work fine 
thank you i will try it
Me too, no current load e no current wattage. I see 14 sensors but not the 2 more important for me.
