Description:
The Get-ParsedTemperature function matches the first CPU temperature occurrence in dumpsys thermalservice output, which comes from the "Cached temperatures" section rather than the "Current temperatures from HAL" section. Aka the device shows 37 degrees under load, not 66.5
Device: Nvidia Shield TV Pro 2019
Expected behaviour: Report current/live CPU temperature (66.5°C)
Actual behaviour: Reports stale cached temperature (37.0°C)

Current temperatures from HAL:

Current cooling devices from HAL:
CoolingDevice{mValue=0, mType=0, mName=FAN}
Root cause:
The regex matches the first occurrence (cached), not the current HAL values.
mValue=([\d\.]+).*mName=CPU\d*
Suggested fix:
Prioritise matching within the "Current temperatures from HAL" section:
Current temperatures from HAL:[\s\S]*?Temperature\{mValue=([\d\.]+),.*?mType=0,.*?mName=CPU
function Get-ParsedTemperature {
param([string]$ThermalOutput)
if (-not $ThermalOutput) { return "N/A" }
# Try different thermal output formats
# Check HAL section first
if ($ThermalOutput -match "Current temperatures from HAL:[\s\S]*?Temperature\{mValue=([\d\.]+),.*?mType=0,.*?mName=CPU") {
return [math]::Round([float]$matches[1], 1)
}
if ($ThermalOutput -match "mValue=([\d\.]+).*mName=CPU\d*,") {
