Bug: CPU usage percentage between HA and Windows don't match

[SpartaTom]

---

Describe the bug
The CPU usage percentage in Home Assistant doesn't match the CPU usage the windows taskmanager performance tab.
Home assistant gives me a value of 1-4%. Windows performance tells me it floats between 15-50%

To Reproduce

1. I've add the 'cpuload' sensor with a refresh time of 5 seconds
2. I've added a gauge card using the sensor now available in HA
3. pressed CTRL+SHIFT+ESC and then went to the performance tab
4. compare the numberic values.

Expected behavior
I would expect the values to match.
At least more closely due to the 5 second refresh time.

Screenshots

Misc info (please complete the following information):

• Windows build: Windows 11 (OS Build 22621.2428)
• Windows' UI language: English
• HASS.Agent version: 2022.14.0

Please check what's applicable (multiple answers possible):

• Installed via installer
• Installed manually
• Problem occurs in HASS.Agent
• Problem occurs in Satellite Service

Additional context
MQTT broker is the mosquitto broker.
Multiple other sensors do match.

@SpartaTom @amadeo-alex were there any further findings on this? I have the exact same issue, as does a friend of mine.

Does it happen on the original or the fork (https://github.com/hass-agent)?

Happens on both

I've recently installed hass.agent, and have the same issue. However, I had previously noticed that a HomeSeer script I have to monitor the same PC is showing the same values as I now see in hass.agent. Both hass.agent and the HS script show CPU usage values that are consistently about 1/6 of what Windows task manager shows. Coincidentally, it is a 6-core i7-8700 CPU. Related?

I'm on the fork and I am seeing the same thing - HASS.Agent reporting CPU usage between 1-4% percent while Windows shows 20-25%.
