tomi, to proxmox

(Link to the original blog post with a proper layout)

It’s a pity that doesn’t report CPU and other temperatures to .

I had several freezes of my old laptop that runs Proxmox due to a stuck CPU fan. I googled a bit and found an elegant solution for temperature reporting: a command_line sensor.

Nevertheless, it took several hours to configure it correctly (I forgot how to deal with ssh keys and similar).

This is the end result:

home assistant cpu temperature sensor chartThe procedure:

  1. I installed the ‘Terminal & SSH’ add-on in to home assistant.
  2. I created SSH keys, put them into /config/.ssh folder, and copied to my proxmox server. Read these instructions. I’ve put something like this in my HA Terminal addon:
$ mkdir /config/.ssh$ ssh-keygen <em># generated ssh keys and when asked, i enter the folder /root/config/.ssh</em> $ ssh-copy-id -i /root/config/.ssh/id_proxmox root@MY_PROXMOX_IP <em># copy keys to my prox server</em>$ ssh root@MY_PROXMOX_IP <em>#try out if I can log on without password prompt, then exit</em>
  1. I had to find out where my proxmox stores temperatures. I ssh’ed to my proxmox again, browsed folders and looked into files which one store temps. My AMD laptop stores it in /sys/class/thermal/thermal_zone0/temp.

It could be also …/thermal_zone1, 2, 3 or similar.

  1. Then I pulled temperature data via SSH to HA terminal:
$ ssh -i /config/.ssh/id_prox -o StrictHostKeyChecking=no -q root@YOUR_PROXMOX_IP cat /sys/class/thermal/thermal_zone0/temp

The command returned 52000.

Edited my configuration.yaml and added the sensor. This is a working code (as of Apr. 2024). I used tips from here (deprecated sensor) and here.

##################

Temperature proxmox

##################
command_line:
– sensor:
name: temperature_cpu
command: “ssh -i /config/.ssh/id_prox -o StrictHostKeyChecking=no -q root@YOUR_PROXMOX_IP cat /sys/class/thermal/thermal_zone0/temp”
value_template: “{{ value | multiply(0.001) | round(1) }}”
unit_of_measurement: “°C”

After 20 restarts of Home Assistant, it finally shows the proxmox CPU temp.

Bonus: here is a picture my homelab proxmox ‘server’ with external fans (because CPU fan is not working).

When I publish a blog post, the WordPress Activitypub plugin delivers the post to the . This causes the CPU to heat to 75C+. I know it now, because I can track its temp. in HA.

The hypothesis is confirmed.

@po3mah @tomi I see. I tried that integration just today, and was a bit underwhelmed that it only delivers "VM up Y/N" -- or are there different integrations? I used proxmoxve.

@tomayac Not 100% sure how you have configured the Nest/why your wifi is in the .86.-subnet and not in the .1. that falls out of the router?
I hope you didn't accidentally configure a double-NAT. Short checklist:

  • make sure that HA has an IP that is pinned down on the DHCP-server (is that the router or the Nest?)
  • start with forwarding 8123 from the router to HA:8123, that should be enough.

1/n

fm_volker,
@fm_volker@mastodon.social avatar

@tomayac It's true that for outgoing traffic double-NAT is not a problem (except conceptually annoying ;-). But if you have it, then incoming you'd need two forwarding rules, one from the Huawei to the Nest, and another one from the Nest to HA, because you can't reach HA directly from the router.

fm_volker,

@jonny Or at least it would force people to develop adequate strategies (rate limiting etc) that would also be useful in different settings, because even if the data is not in S3, the cost has to be SOMEWHERE, maybe behind/on your uplink, and you'd need to defend there as well.

#homeassistant is rejecting pull-requests that touch config options on projects that still use the old configuration.yaml-way, insisting on a #refactoring first.

Ii will be interesting to see how this is going to play out for them long-term. That's probably the only way to muster the required effort for refactoring the codebase, but I wonder how many necessary updates won't get done.

I'm trying to recall if we ever had something similar in the #FreeBSD ports-tree...don't think so. 1/n

The latest MacOS (Sonoma) Calendar-vs-Exchange fsckery is really taking a toll on (my) productivity: calendars just don't sync, workarounds on SoMe do not really seem to work.

on is such a mess -- so many different options: ZHA, , and now I've discovered the -way!

The good thing is that you can cover different use cases, but OMG there must be soo much churn & duplication! I hope there are also synergies, like I learned from Z2M how to OTA "manually" via ZHA.

Next task: look around if anyone's made a chart comparing the different options.

@larsmb I wanted to go with ZHA — again, after switching to a new RPi4. But surprisingly, this time in HAOS, ZHA falls over the Raspbee 2 TTY, whereas the DECONZ-add on (also a container) has absolutely no issues.

How hard would it be to make your own digital photo frame, where multiple people can easily share photos that show up in the "frame"?

Would you need a single board computer and a server and tons of knowledge about databases, or could you just install an app on an old tablet, for example?

#askfedi

fm_volker,
@fm_volker@mastodon.social avatar

@forteller Write up the actual requirements (when/who should be able to delete photos? should this work remotely or just in proximity? ...) and I'll turn this into a Bachelor-project next year at #HVL :-)

(Because I dabble in server-less stuff.)

But I would almost assume that some solution already exists somewhere, and an ESP32 might almost be enough, I'd guess.

I was just robbed for the first time in my life.

Next to a grocery store, two young men asked me if I could change €20 for them. I rummaged in my wallet, and one of the guys distracted me by rummaging in his wallet and discussing what kind of change he needed.

Then the other guy ripped all my banknotes out of my pocket, and they ran away. Since it was dark, I didn't notice any useful details. I reported this to the police, but don't expect to see those €300 again.
