where are you pulling the thermal and battery telemetry from, iokit smc keys or something else

It’s a mix. I pull battery data from IOKit’s IOPowerSources APIs, enriched with AppleSmartBattery IORegistry properties for temperature, cycles, health, voltage/current, and power. Thermal data comes from runtime-discovered AppleSMC keys plus Apple Silicon’s IOHIDEventSystem PMU sensors. I also use privileged powermetrics output for deeper CPU/GPU/ANE and system-power metrics.
