Button and 1-Wire Interfaces
In addition to the buttons on the top side of the module, the module has an external button-interface to connect
two external buttons (make contact). This means, light switches can be connected to the external button interface
to control on/off light commands. For connection regular light switches of all manufacturers can be used.
Within the module, a µ-controller takes over the query of the buttons, the 1-Wire interface and the control of the
relays. Flank control is used to query buttons and 1-Wire component.
The switching status of the relays can be set via the external and internal buttons. Relays can also be set by the
1-Wire Interface. The state of the relay can be read via the 1-wire interface.
External and internal control inputs:
Button interface, external button 1
Button interface, external button 2
Module top side, button 1 internal
Module top side, button 2 internal
1-Wire component, DS2413 channel 0
1-Wire component, DS2413 channel 1
Do not connect any kind of power source to the external button interface! Connecting cables among the module
and the button to other cables should be insulated. In idle mode 5 V direct power can be measured at the
connections of the button interface.

Software / Control
The component is being controlled by 1-Wire Commands for the component DS2413. The relay state will be read
out automatically by the 1-Wire Interface. Relays set via pushbutton interface or manual mode can be read back
via the 1-wire interface.
