Installation

Before you can use your smart-me device, you have to connect it to your Wi-Fi network.

Connect your smartphone or tablet to the WLAN.
Download and install the free smart-me app.
Start the app and create a free account
Click on “Add Device” (+) and follow the instructions.

Quick Start

Device overview
You will ﬁnd the device overview at the top left. To change the grouping of your devices, visit the smart-me web portal.

Counter details
For a detailed view of a meter, click on the menu at the top left and select the corresponding meter.
Event actions and IF / THEN actions
To conﬁgure event actions, go to and select “Edit”. Then click on “Internal Event Actions”. IF / THEN actions can be conﬁgured in the web portal. Example: IF power is greater than 100 watts THEN send an alarm (e-mail).

Outputs S0-0 & S-1
Go to and select «Edit». Then click on «Outputs and Inputs». Both outputs can be conﬁgured here.

Type of output 0
The type of output 0 can also be set to «digital output». As soon as this is saved, an additional switch is visible in the device overview. (Attention max. Switching capacity <0.4W)

Settings digital input/tariff switching
To switch from tariff switching to digital input, go to and select “Edit”. Then click on «Outputs and Inputs». The digital input/tariff input can be conﬁgured here. As soon as this setting is saved, an additional tile is visible.

General Settings
To conﬁgure, the general settings, go to and select «Edit». Then click on «General Settings».

Reactive energy
If this is to be displayed in the app and the web interface, this can be activated here (only possible with a professional subscription).
Setting transformer factor ratio
Go to and select «Edit». Then click on “General Settings”. Now select the transformer factor according to the current transformer used.
You can lock the transformer factor ratio.
After that, the factor cannot be changed until the meter is reinstalled.

Safety Instructions

The safety instructions must be observed under all circumstances:

The device is intended for use in buildings.
The device is intended for operation in a dry, dust-free location without direct sunlight.
Frequent switching on and off can shorten the life of electrical devices. Only set up automatic switching with frequent switching on and off if the connected devices are designed for this. We are not liable for any damage to connected devices.
When installing or changing the device, the conductors connected to the device must be free of voltage.
Touching live parts is life-threatening! For this reason, the relevant pre-fuses must be removed and stored in such a way that other people cannot re-insert them unnoticed.
The device may only be installed by qualiﬁed and appropriately trained personnel.
The local safety and factory regulations must be observed.
For currents greater than 65A, the following cable requirements must be met: Installation cable T, cable Cu bare, cross-section: 35mm2
The energy meter must be installed in a cabinet with protection class IP51 or better
Insulation of Mains Terminal Connections: Reinforced
Insulation of S1, S0-0, and E1 Terminal Connections: If one terminal is used with voltages higher than SELV, Reinforced Insulation is needed for all terminals.

Wiring

T1 button for installation
T2 special functions
In short: If T2 is pressed> 2s, the green LED lamp switches on/ off. If this is activated, it shows the connection status
Glowing green: connected to smart-me cloud Flashing green: connection is currently established, at the moment no connection
Long: If T2 is pressed> 8s, the display of the power is switched between active and reactive power. In addition, the calibration pulse LED alternates between active energy and reactive energy.
Very long: If T2 is pressed> 14s, the S0-0 pulse output is switched between active power and reactive power.
ATTENTION: This setting only changes the display, not in the smart-me cloud (app and website). If the reactive energy is to be displayed in the cloud, this must be done in general settings.

E1 tariff input, potential-free
Tariff 1: 0V (or not connected)
Tariff 2: > 12VAC/DC adjustable as a digital input S0-0 S0 pulse output, potential-free Power MOSFET with
PMAX = 0.4 W, adjustable as a digital output
S-1 power output, potential-free relay with PMAX = 1,500 W
