Digital Inputs

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.

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:

  1. Login to the smart-me website or to the smart-me app

  2. Select a meter and click on "edit".

  3. Click on "inputs and outputs" and select the input as a "digital input"

    • Now, you can give the input a name.

    • You can define a text, which should be showed when the input is "on" or "off".

  4. You see the digital input and its status in the smart-me app and on smart-me website.


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.

Connection

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.

Logic:
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.
