Feature Request: Read Raspberry Pi Temperatures

[Timon]

It would be really nice if we could read the temperatures from any RPi that RaspberryIO is running on. It seems that this should be relatively easy to include into the existing plugin. I would suggest that if you add this you also allow the user to specify either degrees F or C.

Reading temps is quite easy especially from the bash level but it's also easy to read directly from the hardware. Here is an example of the code to read the temps at the bash level.

#!/bin/bash
gpu=$(/opt/vc/bin/vcgencmd measure_temp | awk -F "[=\']" '{print $2}')
cpu=$(</sys/class/thermal/thermal_zone0/temp)
cpu=$(echo "$cpu / 100 * 0.1" | bc)
cpuf=$(echo "(1.8 * $cpu) + 32" |bc)
gpuf=$(echo "(1.8 * $gpu) + 32" |bc)
echo "$(date) @ $(hostname)"
echo "-------------------------------------------"
echo "GPU => $gpu'C ($gpuf'F)"
echo "CPU => $cpu'C ($cpuf'F)"

For now I'm using MQTT to read this but for most users it would be much simpler to be able to get it through RaspberryIO if they are already using it.

Is this CPU temp or some kind of ambient temp on the Pi? Can't imagine the latter would be accurate with the CPU nearby and the Pi often inside some enclosure.

These are the CPU temps. The only way to get ambient temperatures is to add a sensor off of the I2C ports. That would also be nice but it would require a more open interface on RaspberryIO. At that point moving to MQTT is a more open interface to use.

I'm late for the party here. But I really need this capability. The remote Pi is in a location where the temperature of the board needs to be monitored on the main HS Pi in a virtual device. Did you ever come up with a solution that you would be gracious enough to share?
Thanks in advance!
