pafal_reader.pafal_reader.PafalReader

This sensor allows reading out a Pafal 5EC3gr00006 device using a strongly tailored subset of the iec62056 protocol. It can be used to monitor the by the "smart meter" recoreded exported and imported energy.

Dependencies

Uses serial to communicate with via the connected serial device

Requires that sensor_reporter has read/write access to the device file used for communication.

A serial connection to the metering device is required (e.g. via a cp210x UART-USB device like http://wiki.volkszaehler.org/hardware/controllers/ir-schreib-lesekopf-usb-ausgang)

Parameters

Parameter Required Restrictions Purpose
Class X energymeter.read_meter_values.Pafal20ec3gr
Connections X dictionary of connectors Defines where to publish the sensor status for each connection. This sensor has 2 outputs, see below. Look at connection readme's for 'Actuator / sensor relevant parameters' for details.
Level DEBUG, INFO, WARNING, ERROR When provided, sets the logging level for the sensor.
Poll X Positive number in seconds How often to publish the uptime, must be >= 60.
SerialDevice X The serial device file to read from

Outputs

The Pafal20ec3gr has 2 outputs which can be configured within the 'Connections' section (Look at connection readme's for 'Actuator / sensor relevant parameters' for details).

Output Purpose
Import Where to publish the imported energy amount to (OBIS 1.8.0).
Export Where to publish the exported energy amount to (OBIS 2.8.0).

Energy Meter Test script

Using the script test_pafal.py one can check for the connection to the energy meter.

python3 energymeter/test_pafal.py --port /dev/ttyUSB0
