- Clone (or download) this repository (and extract files)
- Run
maketo compile the binary - Execute the binary
./utmp-cli
By default it outputs date, time and the temperature in degrees Celsius, like:
May 13 17:05:02 Sensor C: 22.62
By using -f switch the temperature unit will be changed to Fahrenheit. Date/time formatting is %b %d %H:%M:%S or %Y-%m-%dT%H:%M:%SZ (ISO 8601 in UTZ).
Instead of compiling from the source, already compiled executable could be downloaded from Releases tab.
This application could be also compiled on Windows with a MinGW compiler, see COMPILING.md
Package (with digitemp) is available at opkg-packages.
$ ./usbtemp-cli -h
-f Display temperature using the Fahrenheit scale
-i Format date as UTC ISO 8601
-j Format date and temperature as JSON
-p Set probe precision {9,10,11,12}
-q Quiet mode
-r Get probe serial number (ROM) in hexadecimal, or -R in uppercase hexadecimal
-s Set serial port
Serial port could be anything like /dev/ttyUSB0, COM6 or similar.
User, running binary, must have permissions to write to /dev/ttyUSB0 or similar character device.
Usually, adduser to dialout group or chmod o+rw the character device helps.
