ems-collector

Buderus EMS heating control data collection daemon

ems-collector logs serial data from a connected Buderus heating by interpreting the incoming data and writing it into a mysql database. It also provides a telnet-like interface for sending commands to the heating and receiving a stream of incoming data when being used with a TCP-to-EMS interface (e.g. NetIO with ethersex running on top)

The ems data is described here: http://ems-gateway.myds.me/dokuwiki/doku.php?id=wiki:ems:telegramme

Requirements

(examples for debian wheezy)

For building the collector, libboost is required:

apt-get install libboost1.49-all-dev

If MQTT support is enabled, the minimum required boost version is 1.67, so MQTT support can't be enabled on distributions that only ship older boost versions.

If the collector should be built with MySQL support, the MySQL C++ bindings are needed:

apt-get install libmysql++-dev

For using the bundled (demo) web interface, gnuplot is needed:

apt-get install gnuplot

Clone git repository and compile

git clone https://github.com/maniac103/ems-collector.git
cd ems-collector/collector

There are several compile options for the collector: MySQL support, support for raw read/write commands and MQTT support. Be sure to review the options given in the Makefile and follow them accordingly. Afterwards, start the build:

make

Install

cp collectord /usr/local/sbin
cd ../tools
cp ems-collector.default /etc/default/ems-collector
cp ems-collector.init /etc/init.d/ems-collector

Create a new /etc/ems-collector.conf

nano /etc/ems-collector.conf

now, copy and paste this into the editor and customize to meet your environment:

ratelimit = 120
rc-type = rc30
db-user = <user>
db-pass = <password>

close and save. The room controller type can be passed as either rc30 or rc35.

Make it a service and go

insserv ems-collector
service ems-collector start
