Specifications

The power switch S2-R is a radio controlled universal switch actuator with 

integrated power consumption measurement. In the current flush mount 

version, it is compatible to standard switch boxes and fully integrates into the 

rest of your smart home. It is not only suitable for new buildings, but also for 

existing buildings, because retrofitting has, due to use of radio technology, 

no special requirements to the electrical installation. For new buildings and 

renovations, it helps reducing both planning and cabling costs. The system 

can gradually be extended by adding new components. Determine scope and 

timing at any time by yourself.

The power switch S2-R offers full functionality when combined with other 

components of the ubisys smart home product line and allows for example:

• 

Freely configurable assignments between control elements and consu-

mers

• 

Scenes and group controlling

• 

Time and event controlled actions

• 

Continuous metering

• 

Surveillance

• 

Controlling via smart home display, smartphone app or, as usual, via 

button or switch

More information about the features of the ubisys smart home product line 

can be found at www.ubisys.de.

Installation

The power switch S2-R meets the requirements of DIN 43880 and is 

designed for installation in fuseboxes, mounted on cap rails according to 

EN50022.

Dimensions:

 

 

During installation, the general risks of household voltage networks have to 

be noted!

Basic ZigBee Commissioning

The device joins an open ZigBee network when it is factory new and power 

is applied.

Factory Reset
Power-Cycle Sequencing Factory Reset:

 It is possible to instigate a factory 

reset using a special power-cycle sequence. This is equivalent to selecting 

menu item #5, with the advantage that you need no access to the device 

itself (only to its power supply).

1. 

Power the device for at least four seconds.

2. 

Interrupt the power supply for at least a second.

3. 

Reapply power for less than two seconds but more than half a second.

Notice that at the end of this cycle, the device is off and should remain off for 

at least a second.

4. 

Repeat the previous step two more times, for a total of three short 

power cycles.

5. 

Apply power to the device and leave it powered on. The device will now 

factory reset and reboot.

Factory Reset via Button:

 To reset the device to its factory fresh settings 

(e.g. in order to join it to another network afterwards), press the button in the 

larger of the two holes on the front for more than 10 seconds until the LED 

starts flashing rapidly.*)

Only use the electrically isolated tool provided with the device to press the 

button in the hole.

*) If the device has legacy firmware this feature might not be available. In this 

case, keep the button pressed for one second, until the LED flashes three 

times and then blinks once every second. Then press the button four times 

for less than a second, until the LED flashes five times, followed by a pause, 

then flashes five times again, followed by a pause, etc. In this state, keep the 

button pressed for more than a second until the LED starts flashing rapidly.

Configuration

Upon delivery the factory settings of power switch S2-R has switching inputs 

1 and 2 assigned to the corresponding switching outputs. So it can initially 

be operated autonomously without a radio network.

For integration into the smart home radio network, the spower switch S2-R 

has to be configured first. Direct access to the power switch S2-R is not 

necessary for configuration. That means that network configuration can also 

be done after successful electrical installation. It is best to hold the 16 digit 

serial number of the power switch S2-R in the construction plan during 

installation. This allows you to allocate the device at a later point.

When connected to power, the power switch S2-R automatically logs into the 

ZigBee network. After that it can be configured via the electrician’s installati-

on software (ubisys Network Manager) or the ubisys smartphone app.

ents can be found in the ubisys Smart Home Installation manual.
