smartmeter-readout - Read data from an IEC 62056-21 smart meter
smartmeter-readout [OPTIONS] DEVICE
smartmeter-readout communicates with the smart meter connected to the serial port DEVICE and reads out a full data telegram.
- -h|--help
-
Show the help message.
- -d|--debug
-
Print debugging output.
- -r|--register REGISTER[/LABEL[/FACTOR/FORMAT]]
-
By default, all registers read from the smart meter are shown. When this option is used, only the specified registers are shown.
When LABEL is specified, an optional label is printed along with the value.
FACTOR specifies an optional multiplication factor.
FORMAT specifies a sprintf-style format (default: %f)
The option may be specified multiple times.
- -c|--continuous
-
Enable continuous reading mode. Reads telegrams until the program is stopped using CTRL-C.
- -w|--wait SECS
-
Time to wait between two readouts (when running in continuous reading mode).
- -n|--no-lock
-
Don't check for lock files (potentially dangerous). This will speed up the program by two seconds.
- --callback PROGRAM
-
After each telegram is read, the specified PROGRAM is called and the output is piped into that program. If the program's exit status is different from 0, smartmeter-readout quits with the same status (especially relevant when running in continuous mode).
- --retries RETRIES
-
How many times to retry getting a telegram. If no telegram could be read, the program quits with status 1. Defaults to 5 retries.
