Device pairing

Once the module is properly connected and powered on, the LED inside the housing should begin flashing red, as shown in Fig. 5.1. This indicates that the device is not paired with the SUPLA system. If the LED flashes as shown in Fig. 5.3 or Fig. 5.4, the device must first be removed from the system.

Enabling pairing – AURATON Switch TWO

To activate pairing, hold down the button on the device's housing. Release the button when the LED lights green. The pairing process should begin, and the LED should flash as shown in Figure 5.2. During this time (approx. 30 seconds), initiate pairing on the other device you want to pair with the AURATON Switch Two.

Enabling pairing – Auraton Box gateway

Pairing the AURATON Switch TWO two-channel switch with the AURATON Box gateway can be done in two ways:

On the AURATON Box gateway, briefly press the right "Auraton" pairing button ( ) – the LED under the button will start flashing. Then, put the single-channel switch into pairing mode.

In Supla Cloud, enter the AURATON Box gateway channel and press the "Pair new devices or sensors" button – the LED under the right "Auraton" pairing button will start flashing. Then, put the dual-channel switch into pairing mode.

After pairing the AURATON Switch TWO with the Auraton Box gateway, it is recommended to immediately name all of its channels (2x "Relay" channels and 2x "Electricity Meter" channels) in Supla Cloud. By default, the device is named according to its model or intended use, e.g., "Switch TWO 01," which can be confusing when using multiple devices of the same type. To facilitate identification, it is a good idea to give the device a unique name immediately after pairing. To do this, edit the "Channel Name" and confirm the changes by clicking " Save Changes ."

Factory reset

To restore the factory settings, hold the button during normal operation (approx. 5 seconds) until the LED lights red. Release the button and press it again within 3 seconds to confirm the operation. All information on the device will be cleared. The LED should indicate that it is not connected to the AURATON Box gateway (Fig. 5.1).

Local control

Once the device is properly connected to the power supply (Fig. 3), local load control is possible using switches connected to inputs I1 or I2 . Standard flush-mounted or surface-mounted switches, both bistable (with voltage retention) and monostable (bell) types, can be used. Once connected, no additional configuration is required due to the type of switch included.

Control via the SUPLA application

After successfully adding AURATON Switch TWO to the SUPLA system, the device is visible in the application as two channels (in the figure below: "Light switch – kitchen 1" and "Light switch – kitchen 2"):

After accessing any of the AURATON Switch TWO channels in the SUPLA app, the user has access to three main tabs: General , History , and Settings . Each tab provides different information and control functions.

General tab displays basic device operating parameters in real time. Here you can check:

Active energy consumed (meter reading) – total amount of energy consumed since the device was installed (kWh).
Active energy consumed (current month) – energy consumed by the device in the current calendar month (kWh).
Voltage – current voltage in the network (V).
Current – the current flowing through the device (A).
Active power – current power consumed by the device (W).
Power factor – information about the quality of the power consumed (cos φ).
Active Consumption – alternative view of current energy consumption (kWh).

At the bottom of the tab there are two buttons for manual control of the device:

Turn on – turns on the device connected to the relay.
Turn Off – Turns off the connected device.

History tab allows you to track your electricity consumption over a selected time period. Available options include:

Range – allows you to select the analyzed time period (e.g. last 7 days).
Data type – allows you to select data aggregation (e.g. days, weeks).

The bar chart presents energy consumption for a given period – by default in kilowatt-hours [kWh].

In the Settings , users can customize how data for this channel is displayed. The following options are available:

Value shown in channel list – allows you to choose which value will be visible in the main channel preview. Options include:
- Active energy consumed,
