DomBus is a family of electronic modules for Domoticz, designed and produced by Creasol, an italian company.
DomBus modules are designed to be user friendly and minimize power consumption, and can be used to expand inputs, outputs and sensors for your Smart Home / Building.
One or more devices can be attached to a RS485 serial bus, so with a 4 wire cables (a twisted pair for data and 2 wires for 5-24V power supply) it's possible to connect multiple devices interconnecting the whole building. As the bus carry both data and power supply, using a 12Vdc power supply with backup battery it's possible to get home automation system working even in case of blackout / power outage.
In this folder you can find the python plugin for Domoticz: you can install the hardware plugin by using Python Plugin Manager, or typing the following commands from the linux shell:
#install git, if not already installed
which git
if [ $? -ne 0 ]; then sudo apt install git; fi
#change to the domoticz directory / plugins
cd /home/pi/domoticz/plugins
#fetch the Python Plugin Manager (that can be used to install/upgrade other plugins, including Creasol DomBus)
git clone https://github.com/ycahome/pp-manager
#install python modules: you can use apt (Debian Linux) or pip3
pip3 install requests
#fetch Creasol Plugin
git clone https://github.com/CreasolTech/CreasolDomBus
#restart Domoticz daemon
service domoticz restart
In case of Windows operating system, please follow the installation instructions at https://www.domoticz.com/wiki/Using_Python_plugins#Installing_Python_for_Windows and please note that Domoticz should be restarted to include new python plugins that have been installed.
Then you can find the Creasol DomBus protocol in the Setup -> Hardware panel:
specify a name (for example, dombus), select Type Creasol DomBus and enter the serial device used for RS485 bus.
Now you're ready to connect one DomBus device to the RS485 bus, and check the new I/Os in the Switches panel or Setup -> Devices menu.
Below a list of modules, produced in Europe by Creasol, designed for Domoticz to be reliable and optimized for very very low power consumption.
Our industrial and home automation modules are designed to be
- very low power (around 10mW with relays OFF)
- reliable (no disconnections)
- bus connected (no radiofrequency interference, no battery to replace).
Modules are available in two version:
- with DomBus proprietary protocol, working with Domoticz only
- with Modbus standard protocol, working with Home Assistant, OpenHAB, Node-RED
Store website - Information website
- Single-phase and three-phases, up to 36A (8kW or 22kW)
- Needs external contactor, RCCB (protection) and EV cable
- Optional power meter to measure charging power, energy, voltage and power factor
- Optional power meter to measure the power usage from the grid (not needed if already exists)
- Two max grid power thresholds can be programmed: for example, in Italy who have 6kW contractual power can drain from the grid Max (6* 1.27)=7.6kW for max 90 minutes followed by (6* 1.1)=6.6kW for another 90 minutes. The module can use ALL available power when programmed to charge at 100%.
- Works without the domotic controller (stand-alone mode), and can also work with charging current set by the domotic controller (managed mode)
