Documentation of the Open Energy Monitor binding Bundle

Introduction

Open Energy Monitor binding is used to get live data from open energy monitor devices.

RFM12Pi gateway

rfm12pigw is application read telegram from RFM12Pi module and relay untouched telegrams to openhab via UDP packet. Open Energy Monitor binding listening UDP port and parse data from UDP telegrams.

C code is available on here

build command:

gcc -std=gnu99 -o rfm12pigw rfm12pigw.c

execution:

rfm12pigw -v -d /dev/ttyUSB0 -a 192.168.1.10

Swegongw help is avail be by command execution:

rfm12pigw -h 

For installation of the binding, please see Wiki page Bindings.

Binding Configuration

openhab.cfg file (in the folder '${openhab_home}/configurations').

########################### Open Energy Monitor Binding ###############################
#
# UDP port of the Open Energy Monitor devices (optional, defaults to 9997)
#openenergymonitor:udpPort=9997
#
#openenergymonitor:<parser rule name>=<node address>:<data type(byte indexes)>
#openenergymonitor:<parser rule name>=<node address>:<data type(byte indexes)>

The openenergymonitor:udpPort value specify UDP port which binding will listening. Configuration is optional, by default binding listening UDP port 9997.

Item Binding Configuration

In order to bind an item to the device, you need to provide configuration settings. The easiest way to do so is to add some binding information in your item file (in the folder configurations/items`). The syntax of the binding configuration strings accepted is the following:

openenergymonitor =""
