|HWADDR=0xNNNN||This command set new address for the dombus device: reload the Switch panel to see the new devices associated with the new address of DomBus. NNNN is an exadecimal number, from 0x0001 to 0xff00, so 65280 combinations are available. Keep note of address assegnated to each dombus device, because in case of address conflict it's needed to switch off one of the conflicting device and program the remaining one to another address, or make a factory reset as explained below.|
|INVERTED||Used to invert the logic state of an input or output. Can be used in conjuction with OUT_DIGITAL, OUT_RELAY_LP, IN_DIGITAL, DIMMER.
Normally, domoticz switch is On if input is at logic level high (open), and Off when it's shorted to ground. If INVERTED is specified, domoticz switch will be On when the corresponding input is shorted to ground, and vice versa.
|OUT_DIGITAL||Output, open collector, active low, On => output wire is shorted to GND (max current 50mA). Off => output is open (current=0).|
|OUT_RELAY_LP||Not recommended: output, open collector, active low, but with duty cycle 25% to reduce power consumption on relays coil|
|OUT_DIMMER||Set the output as DIMMER, from 0 to 100% using 5% step, 500Hz frequency. Suitable to control LED strip lights|
|OUT_BUZZER||Set two outputs as BUZZER: a piezo buzzer can be connected to the selected two ports (configured in push-pull) to generate 5KHz frequency when the corrsponding Domoticz switch is On. The Domoticz switch can be configured as selector: in this case buzzer will output 1 or more short alerts to notify a status, similarly to the led configured as OUT_DIGITAL with Domoticz switch configured as Selector.|
Port configured to control a blind, in close direction. Next port will be automatically configured as blind in open direction.
|OUT_LEDSTATUS||Configure a LED port to show the device status (flashes when a frame is transmit to the RS485 bus)|
|OUT_ANALOG||Set output as analog, with 0-10V linear output. It can be used to control another electronic board with 0-10V or 1-10V input (light dimmer, heat pump power, linear valve, ....)|
|IN_DIGITAL||Digital input, is On when the corresponding input is at high voltage level (open), and Off when the corresponding input is at GND (shorted).|
|IN_ANALOG||In DomBusTH there is one pad/hole where it's possible to solder a wire to measure an external DC voltage, <30Vdc; a solder jumper must be opened (because that pad is connected to Vbus).
Also, one or more of the 4 input wires can be configured as analog inputs, 0-3V range: a solder jumper in the PCB must be opened by cutter to disable the internal pullup resistor. Also, external resistive divider should be added to measure higher voltages, so the voltage at the input is less equal than 3V.
On DomBus12 it's possible to use IO7-IO9 ports as analog inputs. Also, it's possible to use IO1-IO4 ports as analog inputs, but in this case it's needed to open, using a cutter, the corresponding PCB jumper PU1-PU4 (that internally connect the input line with a 10k pullup resistor): for example, to use IO1 as analog input, the PU1 PCB jumper must be open. Analog voltage must not exceed the 0-3V range: if voltage range is higher, a resistive divider must be applied externally.
On DomBus23 only IO1 and IO2 ports can be configured as analog inputs: only 0-3V range is supported, and a resistive divider must be externally connected to measure higher voltages.
|IN_COUNTER||Used to count pulses, falling edge (or raising edge if INVERTED option is specified) with debounce (5 pulses/sec max). This solution is perfect to count energy, gas, water, ...If TYPENAME=kWh is also specified in Description, a device with both energy and power will be created.|
|IN_TWINBUTTON||This is a method to connect two pushbuttons/switches to a single input, to get a UP/DOWN/STOP select switch. The two switches are connected together by a 4.7KOhm resistor, using the schema indicated in the application notes below.|
|A||For analog and distance sensors: used to compute the real value using the formula REAL_VALUE=A * VALUE_FROM_DOMBUS + B.|
|B||For analog and distance sensors: used to compute the real value using the formula REAL_VALUE=A * VALUE_FROM_DOMBUS + B|
|TYPENAME||Option to force the creation of a the specified Domoticz. For example, IN_COUNTER,TYPENAME=kWh to create a energy/power meter instead of a normal incremental counter, or IN_ANALOG,TYPENAME=Temperature,A=0.123,B=-50 to get an analog input that return a temperature using the linear equation Temperature=A*x+B where x is the analog value read|
|OPPOSITE||Used for kWh devices, measuring electric power and energy. Suppose to have a PowerMeter Import device, with Unit=98 (see Setup ⇒ Devices), measuring the power/energy from grid, and PowerMeter Export, with Unit=99, measuring the power/energy produced and fed to the grid. If these devices are connected to the pulse output of an energy meter, when a pulse is received from the Import device it means that exported power is 0, and vice-versa. This parameter is used to set what is the Unit number associated to the opposite counter.
So, PowerMeter Import description must have IN_COUNTER,TYPENAME=kWh,OPPOSITE=99 and PowerMeter Export description IN_COUNTER,TYPENAME=kWh,OPPOSITE=98
|DISABLE||Used to disable one or more ports: it can be usedful with large buses with more than 255 ports (devices), because Domoticz has a limit of max 255 devices for each bus. In this case it's possible to disable unused module ports by writing, in the Description of port 1, the list of disabled ports separated by colon, for example
DISABLE=2:5:6:7:11 to disable ports 2,5,6,7,11 of the current module. Port 1 can be never disabled.
To enable a previosly disabled port, just edit the port 1 description for that module, removing the port from the list of DISABLE command: that port will be enabled again in 60 seconds (wait for 1 minute and reload the Domoticz panel).
|DCMD||Dombus Command: through this keyword it's possible to set a command to send to the same or another module, when an event occurs.
In this way, when an event occurs, the module send a command to a dombus module to execute an operation, and this work without the need of a Domoticz controller and without the need to configure Domoticz to manage this kind of actions. See the DCMD section below.
For each port it's possible to configure, through the Domoticz Description field, one or more DCMD commands.
DCMD is a command that is sent to the same or to another DomBus module, in response to an event, and more DCMD commands can be specified for the same event and port.
The syntax is DCMD(Event:ValueLow:ValueHigh)=ModuleAddress.ModulePort:Command:Value
where ValueLow, ValueHigh, Value are optional parameters.
When ModuleAddress corresponds to the same module that we're editing, the command is executed locally, by the same module.
When ModuleAddress corresponds to another Dombus module, the command is sent by bus to that module.
|OFF||This even occurs when input goes OFF||DCMD(OFF)=13.1:OFF
When input goes off, turns OFF also port 1 of module 13
|ON||This even occurs when input goes ON||
|PULSE||Input is pulsed ON for less than 0.5s||DCMD(Pulse)=13.3:TOGGLE
When input is pulsed shortly, send command to module 13 port 3 to toggle it's output OFF->ON or vice versa
|PULSE1||Input is pulsed ON for about 1s||
|PULSE2||Input is pulsed ON for about 2s||
|PULSE4||Input is pulsed ON for about 4s||
|VALUE||Sensor value is in the range between ValueLow an ValueHigh||
|OFF||Turns output OFF. If the optional Value is specified, output will be OFF for the specified time, then returns ON|
|ON||Turns output ON. If the optional Value is specified, output will be ON for the specified time, then returns OFF|
|TOGGLE||Change state to the selected output. If the optional Value is specified, wait the specified time before toggling output|
|number||A number without any suffix should be multiplied by 31.25ms (seconds/32)||1=31.25ms
|numberS||Number of seconds, from 1 to 3600||
|Number of minutes, from 1 to 1440||1m=1 minute
|numberH||Number of hours, from 1 to 43824||1h=1 hour
6h= 6 hours
|numberD||Number of days, from 1 to 1826||
Examples 1: configure a pushbutton switch to have 3 functions:
short pulse => toggle ON/OFF light
1 second pulse => enable ventilation for 30s
2 seconds pulse => disable ventilation
This 3 events can be configured writing in the description of the pushbutton switch:
DCMD(Pulse)=0101.1:TOGGLE, (with a short pulse, toggle port 1 of module 0x0101)
DCMD(Pulse1)=0101.2:ON:30m, (with 1 second pulse => turn on port 2 of 0x0101 for 30 minutes)
DCMD(Pulse2)=0101.2:OFF, (with 2 seconds long pulse, turn OFF the port 2 of 0x0101)
The Domoticz switch Description will be
Example 2: temperature sensor that enable/disable electric heater and valve
In the description field of the temperature sensor we'll write
DCMD(Value:0:20.5)=0101.3:ON, (if temperature between 0 and 20.5°C, turns ON heater on output 3 of module 0x0101)
DCMD(Value:0:20.5)=0102.1:ON, (if temperature between 0 and 20.5°C, turns ON valve output 1 of module 0x0102)
DCMD(Value:20.8:50)=0101.3:OFF (turn OFF heater when temperature above 20.8°C)
DCMD(Value:20.8:50)=0102.1:OFF (turn OFF valve when temperature above 20.8°C)
Domoticz temperature sensor Description will be:
Using RS485 specific cables it's possible to get almost 1km linear bus with several devices attached. Alternatively, it's possible to use 2 twisted pairs of cheap Cat6 UTP or STP cable, one twisted pair for data (A and B) and one for 12-24V power supply. Ideally, all devices should be connected using a linear bus topology, to get the lowest reflection/noise, and connect 100-150 Ohm resistor on the two ends, as illustrated in the Fig. 2. In practice, this is not important for common buildings.
At Raspberry/PC side, it's possible to use a cheap USB-RS485 adapter, if a serial port with RS485 driver is not already available.
Using DomBus modules it's possible to:
Click here if you need to write a microSD card with a clean updated Raspbian+Domoticz image optimized to extend SD life (minimizing writings), and with some addons (firewall, backup, libraries).
This procedure is not needed in case of a new Domoticz installation writing the SD as written above.
If Domoticz does not already include the DomBus plugin, type the following commands (from Linux root shell: type sudo su - to become root):
#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 #fetch Creasol Plugin git clone https://github.com/CreasolTech/CreasolDomBus #restart Domoticz daemon service domoticz restart
After plugins installation and Domoticz restart, it's possible to add the Creasol DomBus hardware (Setup->Hardware , add new "dombus" hardware type "Creasol DomBus" and specify the serial device, normally /dev/ttyUSB0) and connect the DomBus device to the RS485 bus.
DomBus module is factory programmed with a default address indicated above, and only one port will be automatically added to the Switches panel of Domoticz. Enter the Switches panel, find the new device with the DomBus default address, click on Edit and add in the description ,HWADDR=0x0001 to set the new address to 0001, or specify another address of your choice. Reload the Switches panel to see all input/output/led ports of DomBusTH active.
With Domoticz, each DomBus port can be configured via the Domoticz device description: for example a port IN_DIGITAL normally is On when it's left unconnected, and Off when it's shorted to GND, but it's possible to invert this function specifying in the device description the parameter INVERTED, separated by a comma (,): IN_DIGITAL,INVERTED . Relay outputs can be configured writing in the description field OUT_DIGITAL or OUT_RELAY_LP: in the latter case, relay are internally managed to assure a low power consumption.
Please check the sections Ports capabilities and Ports parameters.
Ports that are not used can be disabled in Domoticz Setup ⇒ Devices clicking on the blue arrow of each useless port (device), but in case of a bus with almost 255 ports, it's suggested to disable the unused ports by using the DISABLE command:
1. suppose that DomBus module 0x0001 has ports 3,4,5,6,8 not used
2. in Domoticz Switches panel select port1 of that module ([0001.1] RL1)
3. click on Edit, and add in the Description field DISABLE=3:4:5:6:8 and click on Save.
In this way, the selected ports will be disabled and removed from the Devices list. With this solution it's possible to add more DomBus modules to the same bus, with up to 255 enabled ports. In large buildings, it's a good practice to have more than one bus, to divide floors or areas.
