Noting the discussions elsewhere on the thread, I though the following
might be useful. I take various readings every minute including the CPU
temperature, the ambient temperature and the CPU loading. Having now
had the Pi4 installed in its new home, the following is from the first
full 24 hour period (min max mean) :
CPU Temp 36.5 51.1 41.1
Ambient temp 12.7 18.5 15.6
CPU load % 0.00 1.31 0.09
It will be interesting to see how that works out over a longer period.
Performance wise, it is a vast improvement. Prior to the upgrade on
matplotlib, I had one job running every 10 minutes, taking 5-6 minutes
(11-12 minutes post software upgrade). That now runs in under 1 minute.
