I know this question is a bit specific to the RaspberryPi, so I'll save you the trouble and perform my own countdown 3-2-1-'This is not the correct forum'. Ok, we got that over with...
I'm using some system level calls that worked under 32bit Rasbian for cpu temp and date/time, that now show errors in my flows since moving to 64bit. It's not an individual Raspbeery Pi 4, because I've noted this on all 3 of them that I've moved to 64bit. Of course, it doesn't matter whether it is NR2.2 or NR3.0 either.
I'm attaching a relevant portion of a flow. If anyone has any experience using a different call to the OS to retrieve this info, I'd be happy to hear it. A search of the interwebs and raspberrypi.org hasn't turned it up yet.
