Boiler integration in Domoticz with Ebusd

1. Introduction

The goal of the project is the integration of a Saunier Duval boiler with a Domoticz home automation system.

2. Hardware

– Ebus Adapter : https://ebus.github.io/adapter/index.en.html
– Wemos D1 : https://www.wemos.cc/

3. Software

3.1 Ebus gateway

Download EspTool :

git clone https://github.com/espressif/esptool.git

1	git clone https://github.com/espressif/esptool.git

Go in the folder :

cd esptool/

1	cd esptool/

Download the latest ebus-ESP firmware for our Wemos :

wget https://github.com/john30/ebusd-esp/blob/master/dist/ebus-v2_d1mini.bin

1	wget https://github.com/john30/ebusd-esp/blob/master/dist/ebus-v2_d1mini.bin

Plug your Wemos and flash the firmware :

python esptool.py --port /dev/ttyUSB0 write_flash 0x00000 ebus-v2_d1mini.bin

1	python esptool.py --port /dev/ttyUSB0 write_flash 0x00000 ebus-v2_d1mini.bin

Then reboot the Wemos and :
– Connect to the “EBUS” wireless network
– Open a web browser and go to http://192.168.4.1
– Adjust settings as below :

Your Wemos WLAN Ebus gateway should be ready !

3.2 Ebusd : Ebus daemon

Download the Ebusd package (here for Raspberry Pi) :

wget https://github.com/john30/ebusd/releases/download/v3.0/ebusd-3.0_armhf.deb

1	wget https://github.com/john30/ebusd/releases/download/v3.0/ebusd-3.0_armhf.deb

Install it :

sudo dpkg -i ebusd-3.0_armhf.deb

1	sudo dpkg -i ebusd-3.0_armhf.deb

Then download the latests configuration files :

git clone https://github.com/john30/ebusd-configuration.git

1	git clone https://github.com/john30/ebusd-configuration.git

And copy them :

sudo cp -r ebusd-configuration/ebusd-2.1.x/en/* /etc/ebusd/

1	sudo cp -r ebusd-configuration/ebusd-2.1.x/en/* /etc/ebusd/

Then configure ebusd :

vi /etc/default/ebusd

1	vi /etc/default/ebusd

Here is my configuration (to be adapted) :

# /etc/default/ebusd:
# config file for ebusd service.

# Options to pass to ebusd (run "ebusd -?" for more info):
EBUSD_OPTS="--scanconfig -d 192.168.10.14:9999 --httpport=9999 --latency=20000 --loglevel=error"

# MULTIPLE EBUSD INSTANCES WITH SYSV
# In order to run multiple ebusd instances on a SysV enabled system, simply
# define several EBUSD_OPTS with a unique suffix for each. Recommended is to
# use a number as suffix for all EBUSD_OPTS settings. That number will then be
# taken as additional "instance" parameter to the init.d script in order to
# start/stop an individual ebusd instance instead of all instances.
# Example: (uncomment the EBUSD_OPTS above)
#EBUSD_OPTS1="--scanconfig -d /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A50285BI-if00-port0 -p 8888 -l /var/log/ebusd1.log"
#EBUSD_OPTS2="--scanconfig -d /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A900acTF-if00-port0 -p 8889 -l /var/log/ebusd2.log"
#EBUSD_OPTS3="--scanconfig -d /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A900beCG-if00-port0 -p 8890 -l /var/log/ebusd3.log"

# MULTIPLE EBUSD INSTANCES WITH SYSTEMD
# In order to run muiltiple ebusd instances on a systemd enabled system, just
# copy the /usr/lib/systemd/system/ebusd.service file to /etc/systemd/system/
# with a different name (e.g. ebusd-2.service), remove the line starting with
# 'EnvironmentFile=', and replace the '$EBUSD_OPTS' with the options for that
# particular ebusd instance.

# /etc/default/ebusd:

# config file for ebusd service.

# Options to pass to ebusd (run "ebusd -?" for more info):

EBUSD_OPTS="--scanconfig -d 192.168.10.14:9999 --httpport=9999 --latency=20000 --loglevel=error"

#EBUSD_OPTS2="--scanconfig -d /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A900acTF-if00-port0 -p 8889 -l /var/log/ebusd2.log"

#EBUSD_OPTS3="--scanconfig -d /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A900beCG-if00-port0 -p 8890 -l /var/log/ebusd3.log"

3.3 Domoticz plugin

First of all, we need to upgrade to the last Domoticz Beta version:

cd domoticz
./updatebeta

1 2	cd domoticz ./updatebeta

Then go in the Domoticz folder for plugins :

cd plugins/

1	cd plugins/

And download files :

git clone https://github.com/guillaumezin/DomoticzEbusd

1	git clone https://github.com/guillaumezin/DomoticzEbusd

Set the right permissions :

chmod ugo+x DomoticzEbusd/plugin.py

1	chmod ugo+x DomoticzEbusd/plugin.py

Restart Domoticz :

sudo /etc/init.d/domoticz.sh restart

1	sudo /etc/init.d/domoticz.sh restart

Then configure it with the web interface as below :

With this configuration :

All done !

  Hi,
  
  I ordered the 2.0 version from there : https://forum.fhem.de/index.php/topic,79427.0.html
  
  I’m also selling mine as I’m moving to a new house with a heat pump system without EBUS. Let me know if interested.

My question would be, with this panel I can stop the boiler, the boiler? can you send data directly to the boiler?
Thanks

  Yes, Ebusd allows you to write on the bus!

Hello Ronan,

Can you tell me which csv file you have used for the roomthermostat E7C.
