Incorporate multiple temperature sensors

[vielmetti]

See

https://www.cyberciti.biz/faq/how-to-check-cpu-temperature-on-ubuntu-linux/

for a plethora of sensors that could be monitored; pick several of them for each machine, and send details in some digested, consolidated format.

e.g.

temp.machine.rubus.cpu temp.machine.e-jet.hdd

[vielmetti]

on the 20.04 machine, cat /sys/class/hwmon/hwmon0/device/temp

[vielmetti]

even easier, /sys/class/thermal/thermal_zone0/temp works on the Pi 4 and the Pi 3 both.

surprisingly, sensors doesn't find the right value on the Pi 4 / Ubuntu 20.

grab hdd/ssd temps, per this: https://wiki.archlinux.org/index.php/Hddtemp

Mac OS X

sudo powermetrics --samplers smc -i1 -n1 | grep "CPU die" | sed -E 's/^.*: (.*) C/\1/'

[vielmetti]

Better for Mac OS X

/usr/local/bin/osx-cpu-temp -C | sed -E 's/°C//'

with brew install osx-cpu-temp

/usr/local/bin/weather --json -l 48104 -u si| jq .currently.temperature
