Add CPU temp to overlay list

[BobW55]

Would it be possible to have the Pi CPU temp as an overlay?
Still trying to finalise my enclosure not sure if I want a fan in it or not. Pain to keep hitting the system tab to see the CPU temp.

[EricClaeys]

@BobW55 you have to write a script to get the temp and save it to the overlay variable file. It should be documented how to do that.

[Alex-developer]

@BobW55 I have a module that does this but its not part of the core system and are not supported but you are welcome to try it.

do the following

cd ~
git clone https://github.com/Alex-developer/allsky-modules.git
cd allsky-modules
./install

A menu will appear with a list of module, select the pistatus one and let it install.

This creates a whole series of overlay variables with data about the pi. The one you want for cpu temp is CPUTEMP

Cheers

Alex

[Alex-developer]

Bob Make sure the overlay debug option is turned on, in the module manager look at the settings for the overlay module. Then let Allsky take a single image, this will refresh the data. Then goto the overlay manager and look in the variable manager - the all variables tab and the data will all be in there

[BobW55]

YES debug is ON.
I may have tried to quickly to use it. but after second reboot everything appeared. I see it gives temp in C only. This is fine by me. Its winter in Michigan so heat is not an issue, but come summer I want a way to keep an eye on CPU temp. Not sure if I need to add a bigger fan/heat sink to this thing or not. I like the extra functionality in this release. Just a few instructional hints that I already pointed out that
may trip up newbies like me.

[Alex-developer]

You do have to wait for the next image to be captured before the debug data is updated.

It returns the temp from the OS, I guess this is in C but no one use F do they ;-)

When I get a spare 10 mins i'll add an option for metric or imperial results. Its not s supported module so not high on any priority list

[BobW55]

Imperial or Metric does not matter to me.
Can convert it to fahrenheit close enough in my head. I wrongly thought since it was displayed as both in the systems tab it would be available in the overlay as well.
I do feel the CPU temp should be in the overlay for everyone. It is the one thing that can quickly kill a Pi. The camera is a little more forgiving of high tempuatures.

./install.sh tnx Alex

[EricClaeys]

@Alex-developer, what do you mean no one uses F anymore??? Us crazy, international-ignorant Americans use it. I added the WebUI setting to display temp in C, F, or both for people like me.
LOL

Ideally the module would use that setting.

[Alex-developer]

It was a joke Eric :-)

Good idea on using the setting. I just need to check and see if the temp is always returned by the Pi in C as I am not sure

[Alex-developer]

The pistatus module now looks at the main allsky settings for its temperature unit. If its set to C or F then a single value is created

CPUTEMP

if its set to both then two values are created

CPUTEMP_C
CPUTEMP_F

[BobW55]

Have it set to both. but still only seeing CPUTEMP ?
Do I have to reload the module again?

[Alex-developer]

Have you installed the latest version?

[Dentonknifeworks]

Ok I had just installed this for the first time and it is working as Alex says it should on my end.

[BobW55]

Yes running the latest.

Hello alex, I am trying to use your modules (i am not an expert !) but i got this error :

Installing allsky_pistatus

INFO: Installing dependencies INFO: Installing allsky_pistatus module cp: cannot create regular file '/etc/allsky/modules': No such file or directory ERROR: Installation of allsky_pistatus Failed, Could not copy module from /home/pi/allsky-modules/allsky_pistatus/allsky_pistatus.py to /etc/allsky/modul es

cheers Maxime

Maxime

Do you have the latest dev branch installed?

Cheers

Alex

[maxip2605]

Alex, yes I got lhe latest branch (v1.0.0 4 an).
I did the test with ./install.sh, same error.
I am running Debian Bullseye on a Raspberry pi 4B.

you mean

[maxip2605]

Ok thanks module installed.

[maxip2605]

Alex thanks,
now modules and dependencies for pistatus modules are installed without error messages. Reboot (twice), but nothing happens.
What am i supposed to see on the live view ?

Can you do another pull of the modules and re install the pi status module (I just made a small change to it) - It will ONLY run in the periodic flow now.

If you goto the wiki link at the top of the page and click on the 'New documentation' link it will take you to the new documentation. The pi status module is documented under 'User modules' in the modules documentation.

Just to be clear you need

• The DEV branch for the main allsky project
• The MASTER branch of the modules

Once you have BOTH of the above installed you can use the overlay manager to add the pi status information. Its well worth reading the new documentation as a LOT has changed

Cheers

Alex

[maxip2605]

Alex,
Thanks for the clarification about the need for installing modules.

Today am trying to install a new release (DEV branch) but I have errors with the Python dependencies (openCV error) and installing Python dependencies takes a looonnng time on a Raspberry !

I think that setting the right environnement to support Allsky software installation is a challenge.
I really appreciate the effort with Allsky documentation but I think that a prequisite to install OS on the raspberry would be nice.

There is also branch ALEX, could you tell the difference with the two other branch DEV and MASTER ?
Maxime

[maxip2605]

Alex I am using Python Version 3.10.10. Which version do you recommand ?
I got this error on install :

[Jonk2]

Sorry to hijack the conversation, but I've tried to install the allsky-modules as I'm keen to have a play and help test if I can.

I've just cloned the dev branch and allsky-modules.

Running the install script, I get the selection menu - choosing pistatus I get the following error:

  File "module-installer.py", line 59, in <module>
    user = os.getlogin()
OSError: [Errno 6] No such device or address

Is this me or a system issue? I've also tried sudoing the install script, same result.

Edit - I've got a dev branch installation issue, which may be the cause of this I don't know - I've posted a separate question on that.

[Alex-developer]

No such device or address

Thats odd. The error is saying that you have no terminal. How did you login to the pi?

Can you run a couple of commands on the pi for me

env | grep TTY

env | grep LOGNAME

And let me have the results

Thanks

Alex

[Jonk2]

I use rdp as both pis are headless... the results for your commands are:

pi@allsky:~ $ env | grep TTY
pi@allsky:~ $ env | grep LOGNAME
LOGNAME=pi

I have to say, this is a 64bit system:

pi@allsky:~ $ uname -m
aarch64

...and I'm rapidly moving towards a fresh 32bit installation, even though I don't really want to.

As we speak, I'm trying to at least recover my original working master branch allsky and I'm jumping through some hoops, but getting there. No big deal as my main allsky is untouched, I use this one for testing before throwing things at the main one.

However, these arrors may help you to debug for 64bit systems.

That will be whats causing the problem. The rdp login wont have a tty, I am assuming the user is logged in via a tty.

For now can you login via ssh and run it and I will make a change to allow you to use rdp

Thanks

Alex

[Jonk2]

Ok, I will still probably wipe this and start again with a 32bit OS - it's caused issues before and not much on the pi is going to make use of >3Gb of RAM in a single program so it's kinda pointless for me.

Thanks for the quick response.

This is a job for tomorrow....

I have just pushed a change to the modules repository that fixes this

[Jonk2]

Ok one more try gives this:

Bedtime sorry!

[Alex-developer]

Bedtime sorry!

You need to start allsky, once you have the other issue sorted and it will create the directories in /etc/allsky

[Jonk2]

Given I'm having issues since trying the dev branch, and for whatever reason cannot get the master to work (either new clone or previous installation) it's time to call it quits and start again, this time keeping away from the 64bit OS.

Hopefully, everything will be fine from there.

[Rapid1981]

Hi All!
Would it be possible to add the temperature of the SSD to the variables read by the pistatus module somehow?
This command is only giving back the temperature as a number, but I don't know how I can integrate it to the module.

smartctl -A /dev/sda | grep Temperature_Celsius | awk '{print $10}'

Any help would be appreciated. :)
Thanks!

[BobW55]

You could write a script in python that runs the above command and pass it off to a variable you could use.

SSDTEMP = smartctl -A /dev/sda | grep Temperature_Celsius | awk

Then use SSDTEMP in the overlay.

[Alex-developer]

Can you give me the output of

sudo smartctl --all /dev/sda1

replace sda1 with the appropriate drive

Thanks

[Rapid1981]

With sda1 I got info about the USB to SATA adapter, but with sda, it's the SSD drive itself.

Thanks.

I'll try and find a usb to sata adapter that supports smart and put a simple module together. Will have to be at the weekend as bust until then

Cheers

[EricClaeys]

Please put all future comments in Issue #2893 which is to implement this request.

[Alex-developer]

Module is now written. I need to test it with multiple drives but am awaiting another USB to SATA convertor that support SMART.

Module Options

You can set colours for temp limits if you wish

As soon as I have a second convertor and tested it I will add it to the extra modules repo.
