I/O parameters
Parameter name Function
HWADDR=0xNNNN
This command set new address for the dombus de ice: reload the Switch panel to see the new de ices associated with the new address of DomBus. NNNN is
an exadecimal number, from 0x0001 to 0xff00, so 65280 combinations are a ailable. Keep note of address assegnated to each dombus de ice, because in
case of address conflict it's needed to switch off one of the conflicting de ice and program the remaining one to another address, or make a factory reset as
explained below.
INVERTED
Used to in ert the logic state of an input or output. Can be used in conjuction with OUT_DIGITAL, OUT_RELAY_LP, IN_DIGITAL.
Normally, domoticz switch is On if input is at logic le el 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 ice ersa.
OUT_DIGITAL Output is managed as digital, On when it's acti e and Off when it's disabled.
OUT_RELAY_LP Relay output managed in low power sa ing mode, to reduce relay coil current consumption at less than 30% of normal alue.
IN_DIGITAL Digital input, is On when the corresponding input is at high oltage le el (open), and Off when the corresponding input is at GND (shorted).
DISTANCE Set the current port as the echo output of ultrasonic distance meter: IN3 will be used to pro ide the trigger to the distance meter (see application schema).
Setting a de ice as DISTANCE, it will be mo ed to the Utility panel of Domoticz.
AFor analog and distance sensors: used to compute the real alue using the formula REAL_VALUE=A * VALUE_FROM_DOMBUS + B.
BFor analog and distance sensors: used to compute the real alue using the formula REAL_VALUE=A * VALUE_FROM_DOMBUS + B

10 IN AC/OUT
SSR IN_AC, OUT_DIGITAL IN_AC INVERTED
230Vac line sensing, used to detect blackout or line oltage. DomBus1 board can be modified to replace
the circuitry with a 60V 100mA SSR (current consumption less than 1mA), suitable for controlling a siren
or other security de ice, heating system or another low oltage de ice.
Application note: measures the level of a ater tank, activates a valve for atering the
garden, turns on/off the night light and read magnetic contact sensors of door+blind
The following schema shows how to connect a waterproof ultrasonic distance sensor to Creasol DomBus1 to measure
the le el of water tank, so the garden irrigation program on Domoticz can determine if there is anough water in the
tank. DomBus1 returns the distance alue in mm, and it's possible to program the de ice to get a linear transformation
of this measure using the formula VALUE=A*mm+B. In this example, distance is measured in cm, the tank height is
200cm from the sensor, so to measure the le el of water A=-0.1 and B=200 , so when DomBus1 returns 1800mm of
distance (from sensor, placed in the top of tank, to water le el), VALUE=-0.1*1800+200=-180+200=20cm (le el of
water from the bottom of tank).
These parameters can be easily set in the de ice description: enter Switches panel, locate and edit the IN2 switch, and
write in the description DISTANCE,A=-0.1,B=200 and sa e: Domoticz automatically remo e the de ice from the switch
list and create a de ice in the Utility panel, showing the correct alue compute with the parameter A and B indicated.
DomBus supports at max 2 distance de ices, connected to IN1 and IN2; trigger to distance meters is sent using the
IN3 port, that is reser ed for this function and can be disabled on the Setup -> De ices (clickin on ).
As the Creasol DomBus1 de ice has many inputs and outputs, in this application note the same DomBus is used also
to acti ate the garden watering pump, acti ate the night lights, and control the magnetic contact sensors for a door and
blind, as like as the MCS tamper.
Factory reset
To restore default parameters, remo e power supply, push and hold the button Prog and supply the de ice: red led starts flashing; after 5 seconds it stops
flashing and de ice restores the configuration to default settings.
This procedure can be useful when 2 DomBus de ices ha e the same address and one of these cannot be disconnected or changed.
Safety information
The appliance must be disconnected from the power supply before carrying out any installation work. Electricity must be remo ed e en for the external
de ices connected to the board (e.g. ligths, pumps, electronic boards,... connected to the relay outputs).
Installation and maintenance must be carried out by a qualified technician, in compliance with the manufacturer's instructions and local safety regulations.
The electronic board must be installed into a well protected plastic enclosure, well protected by accidental contact with other metal objects.
Power supply must be protected by a fuse, as indicated in the application schema. External de ices can be connected to the board only if they meet the
specifications indicated in the Features and specifications section. The manufacture do not respond for improper use or connection of this de ice.
Disposal
The packing material is 100% recyclable and should be disposed in the appropriate recycle bins. The electronic board cannot be disposed as household
waste, but must be disposed of correctly or returned to the seller when purchasing a new equi alent product. Hea y fines can be imposed by local laws for
illegal disposal. By ensuring this product is disposed of correctly, you will help a oid potential negati e consequences for the en ironment and human health,
which could otherwise be caused by inappropriate waste handling of this product.
