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 :
|
1 |
git clone https://github.com/espressif/esptool.git |
Go in the folder :
|
1 |
cd esptool/ |
Download the latest ebus-ESP firmware for our Wemos :
|
1 |
wget https://github.com/john30/ebusd-esp/blob/master/dist/ebus-v2_d1mini.bin |
Plug your Wemos and flash the firmware :
|
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) :
|
1 |
wget https://github.com/john30/ebusd/releases/download/v3.0/ebusd-3.0_armhf.deb |
Install it :
|
1 |
sudo dpkg -i ebusd-3.0_armhf.deb |
Then download the latests configuration files :
|
1 |
git clone https://github.com/john30/ebusd-configuration.git |
And copy them :
|
1 |
sudo cp -r ebusd-configuration/ebusd-2.1.x/en/* /etc/ebusd/ |
Then configure ebusd :
|
1 |
vi /etc/default/ebusd |
Here is my configuration (to be adapted) :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
# /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. |
3.3 Domoticz plugin
First of all, we need to upgrade to the last Domoticz Beta version:
|
1 2 |
cd domoticz ./updatebeta |
Then go in the Domoticz folder for plugins :
|
1 |
cd plugins/ |
And download files :
|
1 |
git clone https://github.com/guillaumezin/DomoticzEbusd |
Set the right permissions :
|
1 |
chmod ugo+x DomoticzEbusd/plugin.py |
Restart Domoticz :
|
1 |
sudo /etc/init.d/domoticz.sh restart |
Then configure it with the web interface as below :
With this configuration :
All done !
