CLEMAP One can measure the power consumption of a single apartment or house. With the web application you can discover which device category consumes electricity in your house and how much it costs.

CLEMAP One is installed in or next to the junction box or electrical cabinet and must be connected to the power supply cables between the meter and the house.

Usually there are three input cables in an apartment or a house: the phase conductors (L1=brown, L2=black and L3=grey) and as output the neutral conductor (also called N=blue). The three current sensors must be connected to all three incoming cables.

As the installation requires an intervention in the household network, we recommend to contact an electrician for doing the installation.

Installation requirements

Before starting the installation, check that the following points are fulfilled:

1.     You have a smartphone or laptop to activate CLEMAP One.

2.     There is enough space in your junction box or electrical cabinet to install CLEMAP One.

a.     Yes → Continue with step 3.

b.     No → Check whether you can install CLEMAP One next to the junction box / electrical cabinet. CLEMAP One can also be installed in other junction boxes in the house, e.g. in the housing enclosure within an apartment. Continue with point 3.

3.     Does your wireless home network reach the CLEMAP One installation location? (Checking wireless reception with a smartphone at the CLEMAP One installation location)

a.     Yes → Start the installation.

b.     No → Install a Power Line Adapter (e.g. the Netis PL7622 Wireless Powerline Adapter) or a Wireless Repeater and continue with the installation.

Power cable colors and their meaning

The function of each conductor can be recognized by the color of the power cable if the electrical installation has been performed correctly. But attention: Old buildings often have an invalid coloring of the conductors, as the standards have been changed several times over the years.

There are basically three types of cables. First of all there is the live conductor, the outer conductor, which is also called phase (L) or phase conductor. Then there is the neutral conductor (N), which is often colloquially referred to as the neutral conductor, even if technically it is actually understood to mean something else. And finally the earth conductor (PE), which is also called earthing, earth conductor or simply earth.

Listed below are the colours of the power cables:

In old houses, however, you cannot expect the colors of the cables to be correct.

Step 1: Electrical installation

Step 1 Warning.png

Picture 3.png

1.     Make sure that the power supply in the junction box or electrical cabinet is disconnected.

2.     Place CLEMAP One (a) so that the current sensors (b) can be easily connected to the main power cables (L1, L2 and L3) (as shown in Picture 2).

3.     Install CLEMAP One in or next to the junction box / electrical cabinet.

4.     Connect the current sensors (b) to the insulated incoming power cables (L1, L2 and L3) and make sure that the arrow shown in Picture 3 indicates the house direction (and not the meter/power supplier direction).

5.     Connect the current sensors (b) to CLEMAP One and make sure that the current sensors of the L1, L2 and L3 cables match the appropriate voltage inputs L1, L2 and L3.

6.     Now connect cables (c) after a fuse (maximum 16 A). Connect L1 with color brown to phase 1, L2 with color black to phase 2, L3 with color grey to phase 3. The blue cable has to be connected to the neutral conductor.

7.     Turn on the fuses and wait 3 minutes for the sensor to be activated.

Step 2:

CLEMAP One connection to a wireless home network

1.     Connect your smartphone or laptop to the wireless network created by CLEMAP One

(Wireless Network Name: Clemap-Nibble, Password: sensorsetup).

2.     With a browser go to

Step 2 - 1.png

3.     Registration with

·       User: clemap

·       Password: Serial number on the cover (for example SE03123456)

4.     Check briefly whether the displayed consumption values (P, V and I) are realistic for the three phases L1, L2 and L3. If any doubt, contact your electrician. If a failure occurs, check the arrow direction of the current sensors, that each current sensor match to the correct voltage phase and that the current sensors are connected to the right incoming power cables.

5. Select "Wifi Settings", select your wireless network from the pop-up menu and enter your wireless password. ATTENTION: CLEMAP One only supports wireless on the 2.4 GHz frequency band.

Step 2 - 3.png

6.     After saving the wireless password, you can log out. Within a few minutes, the sensor will be connected to the selected wireless network.

Step 3: Sensor activation on

You will soon have full control over your electricity consumption. Now all you have to do is activate the sensor.

1.     Use a browser to go to or download the CLEMAP app from the App Store or Google Play.

2.     Select "Register" (you will need the serial number and activation code delivered with the sensor and/or written on your CLEMAP One).

3.     Follow the online instruction.

Step 3 - 1.png

Once the installation is complete, the sensor starts measuring your power consumption and mapping it to the appropriate devices in your household. Over time, the algorithm learns to categorize the different appliance categories and automatically displays this on the web application.
