I am writing a script to procedurally measure certain power system parameters.

I am aware of system_profiler SPPowerDataType. However, this API only updates once a minute and sometimes provides quite different results than iStat.

iStat has a number of different sensors for current draw (amperes), all of which update once per second. It also has a power bus (PBus) voltage which updates once per second.

    Have you contacted the iStat Menu developers and asked them? – fsb Mar 2 '17 at 15:56
  • A license for iStat menu is at bjango.com/help/istatmenus4/licenseagreement. They don't want to share their source code. They may feel like discussing what API they use, but my bet would be against that. – D A Vincent Mar 4 '17 at 23:46
  • I contacted them a few days ago, still waiting on a response. – stands2reason Mar 6 '17 at 17:58
