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.
