Input and Output Configuration

Output configuration

The smart-me meters have one or more outputs that can be used as pulse outputs or as potential-free contacts. The S0_0 output is defined as a pulse output and the S1 as a digital relay output with the name "Relay".

Impulse output

It is possible to configure the output as a pulse output. It is possible to distinguish between reactive and active energy.

Note: It is not possible to distinguish between import and export. The absolute value is always output.

Configuration as a potential-free contact

If the output is defined as a potential-free contact, any devices can be controlled on the smart-me cloud. The control can happen manual (on/off) or automatically (via the events and actions).

The S1 can also be hidden from the view by switching to impulse output if it is not used as a digital output.
In the tenant view, these cannot be activated or deactivated even if they are visible there.

The smart-me meters have a digital input that can be used as a tariff input or as a normal digital input. This input is defined as a tariff input at the factory. If the input is configured as a digital input, it can be used as an event to control other devices or trigger alarms. 

Wiring of the outputs

Observe the maximum voltage, current and power values of the respective outputs. Simplified, each of the potential-free outputs can be considered as an unconnected switch. For a function to be given, a circuit from high to low potential must be made possible.

Input configuration

Configuration as a digital input

If the input is defined as a digital input, it can be used as an event to control other devices or alarms. To configure an input as a digital input, proceed as follows:

Use digital input for controls

You can use the digital input to switch other devices or send alarms. For this purpose, the "Switching state" if event can be defined under the if / then actions.


To switch the potential-free contact, an external voltage must be applied. The respective voltage values can be found in the technical data of the individual products.  

1 (High) = Voltage from data sheet
0 (Low) = 0 volts

Note: With DC voltage, attention must be paid to the polarisation (E1+/E1-), whereas this does not matter with AC voltage.
