it is not what I am looking for. Thanks anyway

What’s wrong with SNMP if I may ask, I’m monitoring various servers and other IT devices through SNMP, it definetly allows to monitor CPU, mem, HDD usage and thousands of other parameters of my servers.

I started trying to do this but haven’t had a lot of time. What I figured out is that if you’re running HA in your Unraid instance then you can mount usr/local/emhttp/state and pass it to HA (important to do as read-only), then you’ll need to parse the contents.
This is my EXTREMELY HACKY version of a custom component is available here in case someone wants to spend some time turning it into something decent.

This seems great, However I seem to get this error

Perhaps you have an updated script?
Still using the same script with no issues.
From your error I think you might have an extra [0] after [‘total_utilization’]… can you remove the [0] and let me know if that did the trick? If not ill try to have a look
sorry, ignore the [0] i was trying stuff to try and make it work, even without that it still doesn’t seem to work. any ideas?
what version of HA you on?
(not sure what happened to my other posts, HA forum and my browser went a bit weird)
Can you make sure you are you mounting unraid’s folder: usr/local/emhttp/state (which is where all the infor is stored) as read only into a folder in the hass container named unraid_metrics
Yeah i am, i can access it from the homeassistant docker via exec aswell, permissions potentially an issue if homeassistant it self runs under a different user to the docker exec?
So i decided to go a more plug and play route, here is a unraid plugint that converts the ini files to json for easy reading from HA with a rest sensor Unraid JSON API
Care to share the code to make that pretty pretty monitoring?
Sorry exactly where is the yaml for this page?
Good moening,
Can you please explain how to install this monitoring dashboard.
I have installed the unraid api and created the account on the web ui with unraid IP.
Then i created a unraid_monitoring.yaml with link you provide.
At this point i dont understand what to do
Hi All,
I came across this custom component to monitor unraid in HA.
I added it via HACS and it errors on version missing from manifest.json. Just edit the file and add
“version”: “0.1”,
I cannot get it to work and the maintainer archived the repo.
I’m sure someone with python experience can get this to work easily.
Hoping to resurrect an old thread. UnraidAPI is now broken and the custom component listed above has been archived. Are there any new methods besides Glances that will enable me to monitor things in HA? Glances doesn’t provide Docker or VM stats or any control functionality.
There is a fork in the making.
Still buggy for me. Hope this gets fixed.
Came here looking for a way to monitor my HDD temperature in HA.
I’m using Glances. It works for everything but HDD temp (maybe it can, idk).
Just run the docker on Unraid and connect HA to it.

Hi all, I have started to develop a custom integration for unraid. Feel free to check it out.
So before you go and open issues on GitHub, Please note, I have only tested it on my UNRAID server with 4 drives in the array and a cache drive. I’m still figuring out how to get the code to automatically add other pool devices and one day support zfs pools.
I’m also still working on getting the HDD temps in for each disks.
Still a bit of work to do
