something to keep in mind, is that pi5 and previous models, use a different ioctl for the vcgencmd
on pi0-pi4, vcgencmd runs over vchiq
but on the pi5, vchiq was just deleted, and its now over the mailbox
looks like your already using the mailbox one, ive theorized that that works on older models too

ive also got a similar tool, thats python based and just runs the vcgencmd binary, scrape time is generally under 200ms
