A simple golang command-line that takes a reading of a TEMPer USB and prints it to STDOUT. Uses the temper library.
Make sure you have a working Go environment (Go 1.12+ is required). See the install instructions.
To install temper-cli, run:
go install github.com/taigrr/temper-cli@latest
On Linux you need to set up some udev rules to be able to access the device as
a non-root/regular user.
Edit /etc/udev/rules.d/99-temper.rules and add these lines:
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="e025", GROUP="plugdev", SYMLINK+="temper%n"
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="0c45", ATTRS{idProduct}=="7401", GROUP="plugdev", SYMLINK+="temper%n"
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="0c45", ATTRS{idProduct}=="7402", GROUP="plugdev", SYMLINK+="temper%n"
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1130", ATTRS{idProduct}=="660c", GROUP="plugdev", SYMLINK+="temper%n"
Note that there are many versions of the TEMPer USB and your
idVendor and idProduct ATTRs may differ.
This cli is tested with the model available here.
This is not an endorsement of the product.
Make sure your user is part of the plugdev group and reload the rules with
sudo udevadm control --reload-rules.
Unplug and replug the device.
