Temperature not registering on RPi4

[Ryland0]

Not sure if this is a thing (supported), but I have eOS running on a Pi 4 with Monitor and everything works except for the temperature. I can provide any information requested if there is even an interest in this.

[stsdc]

Well, RPi 4 is not my priority (and I don't have one), however I'm open to PRs.

Roadmap:

1. Find a file that provides temperature info
2. Look at the code that parses temperature
3. Basically add another if statement

P.S. I'm amazed that it compiles and runs!

[Ryland0]

Testament to your coding I suppose. Not a single hiccup compiling.

I'm not terribly familiar with gihub and PRs, so please let me know if this is helpful. And again, if its not worth your time that's cool. I appreciate your response.

Please, cat /sys/class/hwmon/hwmon0/name. Need what's inside the name file.

ryan@elementary-pi:~$ cat /sys/class/hwmon/hwmon0/name cpu_thermal

@Ryland0 please check the dev branch. Let me know if 52ee3f9 commit did the work.

[Ryland0]

I hope I did this correctly.

Cloned the project again.
Modified the vala file.
Rebuilt.

No errors, but also no change. Not sure if it matters, but during ninja, I got this reference a few times.
Installing ... to /usr/lib/aarch64-linux-gnu

Is that right?

[stsdc]

Did you checkout to dev branch?
What did You modified?

[Ryland0]

git clone https://github.com/stsdc/monitor
cd monitor
nano /src/Resource/TemperatureSensor.vala
added entries for //Raspberry Pi 4 from 52ee3f9 exactly as shown
meson build --prefix=/usr
cd build
sudo ninja install

[stsdc]

Why to do this when You can just git checkout dev all the changes will be there. No need to copy manually.

What shows up when you run in debug mode G_MESSAGES_DEBUG=all ./com.github.stsdc.monitor ?

[Ryland0]

Honestly, I'm not familiar with the ins and outs of github. It's not just pull requests. Sorry.

From the debug, I get this at the start and the WARNING line repeats itself over and over later on.

** (com.github.stsdc.monitor:23405): DEBUG: 16:53:19.970: TemperatureSensor.vala:69: Found temp. sensor: cpu_thermal

Interesting...

hwmonx_prop[4] should be "1" and it is "n"

I did recreate an exact path on my PC and managed to get a test value. You have to figure out why is there a "n" instead of number. Or wait for me to buy a Raspbery Pi 😉, but I don't know when it will happen

[Ryland0]

That's cool. I really do appreciate you looking into it.
