The default baud rate is 115200.

This code originated from here: https://www.wattsupmeters.com/forum/index.php?topic=8.0 This program is released under the GPLv2.

To compile the binary, type "make".

Sample usage is as follows:

./wattsup -c 1 ttyUSB0 watts

This will connect to WattsUp once and output the watt usage.

Here is a summary of command-line options:

$ wattsup wattsup Version 0.03 A program for interfacing with the Watts Up? Power Meter

Usage: wattsup [ ... ] [ ... ]

is the serial port to which the device is connected.

is any of the following: -h | --help Display help text and exit -V | --version Display version information and exit -d | --debug Print out debugging messages -c | --count= Specify number of data samples -z | --final Print final interval information -f | --delim= Set field delimiter (default ", ") -n | --newline Use '\n' as delimter instead -t | --localtime Print localtime with each data reading -g | --gmtime Print GMT time with each data reading -l | --label Show labels of each field -s | --suppress Suppress printing of the field description -b | --calibrate Print calibration parameters -r | --header Print data field names (as read from device) -i [] | --interval[=] Get/Set sampling interval -m [] | --mode[=] Get/Set display mode -u [] | --user[=] Get/Set user parameters -a | --show-all Show all device parameters -N | --no-data Don't read any data (just read device info) -S | --set-only Set parameters only (don't read them back)

specifies which of these to print out (default: ALL) watts -- Watt Consumption volts -- Volts Consumption amps -- Amp Consumption kwh -- Average KWH cost -- Cost per watt mo-kwh -- Average monthly KWH mo-cost -- Monthly Cost max-watts -- Maxium Watts Consumed min-volts -- Maximum Volts Consumed max-amps -- Maximum Amps Consumed min-watts -- Minimum Watts Consumed max-volts -- Minimum Volts Consumed min-amps -- Minimum Amps Consumed power-factor -- Ratio of Watts vs. Volt Amps duty-cycle -- Percent of the Time On vs. Time Off power-cycle -- Indication of power cycle frequency -- AC frequency (HZ) VA -- VA

Examples:

• Print header line and read all fields once per second: wattsup ttyUSB0 -r -s

• Read all fields once per second and print a label with each field: wattsup ttyUSB0 -l

• Test connection, but do not read measurements: wattsub ttyUSB0 -N
