How to monitor the power of CPU/GPU in watts with this software. Or is that possible?

[Yu0413]

Hi, I recently bought this set of small monitor screens because I enjoy monitoring the hardware status of my computer.
However, I noticed that none of the default themes have the ability to display CPU and GPU power in watts.
I was wondering if this alternative software can achieve that?

I understand that I can find all the available items in the theme examples, but it seems that power is not included.
Is it possible to add power monitoring?
Or is this item not capturing power values at the core level?
Can you help me with how to proceed?
Thank you.

I'd like to know that too

Hi,

I did it by adding in sensors_custom.py the code below. Maybe you have to adjust the sensor Name search depending on what you can see in the LibreHardwareMonitor report (check sensors_custom wiki)
Maybe some easier solution exists but at least this one I created works for me.

class GPUPOWER(CustomDataSource):
    def as_numeric(self) -> float:    
        gpu = get_hw_and_update(Hardware.HardwareType.GpuNvidia)
               
        for sensor in gpu.Sensors:
            if "Package" in str(sensor.Name) : 
                return float(sensor.Value)

        logger.error("GPU Power cannot be read")
        return math.nan
            
    def as_string(self) -> str:
        return f'{int(self.as_numeric()):>3} W'

class CPUPOWER(CustomDataSource):
    def as_numeric(self) -> float:    
        cpu = get_hw_and_update(Hardware.HardwareType.Cpu)             
        for sensor in cpu.Sensors:
            if "Package" in str(sensor.Name) : 
                return float(sensor.Value)

        logger.error("CPU Power cannot be read")
        return math.nan
            
    def as_string(self) -> str:
        return f'{int(self.as_numeric()):>3} W'   

After that you can simply use them in the theme.yaml with something like that :

    GPUPOWER:
      TEXT:
        SHOW: True
        SHOW_TEXT: True
        SHOW_UNIT: True
        X: 240
        Y: 295
        FONT: generale-mono/GeneraleMonoA.ttf
        FONT_SIZE: 15
        FONT_COLOR: 2, 216, 243
        BACKGROUND_IMAGE: background_new.png
    CPUPOWER:
      TEXT:
        SHOW: True
        SHOW_TEXT: True
        SHOW_UNIT: True
        X: 70
        Y: 295
        FONT: generale-mono/GeneraleMonoA.ttf
        FONT_SIZE: 15
        FONT_COLOR: 2, 216, 243
        BACKGROUND_IMAGE: background_new.png

Thanks! It works. Though LibreHardwareMonitor show more cpu power package than hwinfo.

EDIT.
I found the problem for intel CPU in LibreHardwareMonitor is two values Package first for temperature and second for power.

I fixed that very simple:

class CPUPOWER(CustomDataSource):
def as_numeric(self) -> float:
cpu = get_hw_and_update(Hardware.HardwareType.Cpu)
for sensor in cpu.Sensors:
if "CPU Package" in str(sensor.Name) and sensor.SensorType == Hardware.SensorType.Power:
return float(sensor.Value)

      logger.error("CPU Power cannot be read")
      return math.nan

  def as_string(self) -> str:
      return f'{int(self.as_numeric()):>3} W'

Thank you, I did not take care of this !
I fixed it on my side too with your solution.

Hi
Can you please upload the files or proper instructions?

Hi, I don't know what I'm doing wrong, but neither my cpu nor gpu is working

[Ladik12345]

Hi, thanks for the help, I don't know anything about it, I'm just a regular PC user. I don't know why I didn't want to go, in the end I made a mistake and put it in the pile somehow. Thank you for the muster and sorry for the English, it's through a translator. class GpuNvidia(CustomDataSource): def as_numeric(self) -> float: gpu = get_hw_and_update(Hardware.HardwareType.GpuNvidia) for sensor in gpu.Sensors: if "Package" in str(sensor.Name) : return float(sensor.Value) #return float(50) logger.error("GPU Nvidia fan percent cannot be read") return math.nan def as_string(self) -> str: return f'{int(self.as_numeric())}w' def as_histo(self) -> list[float]: pass class CpuPower(CustomDataSource): def as_numeric(self) -> float: cpu = get_hw_and_update(Hardware.HardwareType.Cpu) for sensor in cpu.Sensors: if sensor.SensorType == Hardware.SensorType.Power: return float(sensor.Value) #return float(50) logger.error("CPU Power cannot be read") return math.nan def as_string(self) -> str: return f'{int(self.as_numeric())}w' def as_histo(self) -> list[float]: pass

Hello,

I tryied to retrieve GPU HotSpot temperature from LHW by adding this small code lines to sensors_custom.py:

class GPU_HOTSPOT (CustomDataSource):
    last_val = [math.nan] * 10
    
    def as_numeric(self) -> float:
        GPU = get_hw_and_update(Hardware.HardwareType.GpuAmd)
        
        self.value = math.nan
        
        for sensor in GPU.Sensors:
            if "Hot Spot" in str(sensor.Name) : 
                self.value = float(sensor.Value)
                
                break
        
        self.last_val.append(self.value)
        
        self.last_val.pop(0)
        
        return self.value
    
    def as_string(self) -> str:
        return f'{self.value:>5.0f}°C'
    
    def last_values(self) -> List[float]:
        return self.last_val

But I got this error, seems sensors_librehardwaremonitor.py is not charged atm...

[ERROR] Error loading custom sensor class GPU_HOTSPOT from sensors_custom.py : name 'get_hw_and_update' is not defined

Has anything changed since the new updates about this? Using 3.5.0 version.

Thank's.

[Jaxeman09]

i fixed your issue
i will send my fixed version for you soon

[Jaxeman09]

@Jidoeuf and @Queven didnt mention that you have to put in the start of the librehardwaremonitor sensor sheet into the sensors_custom for the sensors to be retrieved, @dkdirekt had issue because he didnt know this and his entire issue was because he was missing the start of librehardwaremonitor.py

[elooneyru]

Please, help

[ERROR] Error loading custom sensor class GPUPOWER from sensors_custom.py : Can't instantiate abstract class GPUPOWER with abstract method last_values

[Jaxeman09]

Thank you
Good luck on getting your gpu to show its power, if i remember when i wake up i will run the sensor test on my dads 5070 ti and see if it gives correct power readings

[rovili]

Are you also running the latest nvidia driver? 591.59?

[Jaxeman09]

unfortunately my 1080 lost support so i am stuck with 581.80 as my latest, dads 5070ti i can test 581.80 and 591.59 for you

[rovili]

Oh, ask you Dad to swap GPUs! :)
It works now... a simple reboot brought GPU Power back.
Only thing is now, it shows xx.xW. How can I only get XXW? Figured out -> 5.1f to 5.0f.

What I noticed, with my 9800X3D, LibreHardwareMonitor does not read clock of the CPU correctly. Grml.

[Jaxeman09]

it should be reading actual clock vs task managers effective clock, so it should be the correct reading
