Want to get easy access to temperature information on on Firewalla via the terminal or for scripting? This is what you need.

Installation & Persistance

Firewalla may remove anything installed after upgrades, so you can install a script to reinstall for you after firewalla upgrades and possibly some reboots.

Log in to firewalla with ssh. Then type:

cd ~/.firewalla/config/post_main.d/

if no directory is found:

mkdir ~/.firewalla/config/post_main.d/
cd ~/.firewalla/config/post_main.d/

Then save this script and make it executable using vi or nano. For example

sudo vi m_sensors.sh

Copy/Paste this script at https://gist.github.com/mbierman/bc6b9f11c82f6fd7efdafac269fb058d and save and close.

This should give you a file at ~/.firewalla/config/post_main.d/m_sensors.sh

Then change permissions and run it.

sudo chmod a+x install_speedtest.sh
~/.firewalla/config/post_main.d/m_sensors.sh

# now try it out: 

sensors -f
pi@firewalla:/data (Gold) $ sensors -f
