Everything about commissioning smart-me devices: What should be considered during commissioning, common sources of errors and specific answers to installation questions.


WiFi requirements

  • WiFi 802.11 b/g/n with 2.4 GHz (the WiFi standard with 2.4 GHz has a better range than the 5 GHz network)*.

  • Port 80 UDP (data transmission) and port 53 DNS (name resolution) must be open.*

  • The router must be connected to the Internet*.

  • The SSID must not be hidden. Our devices cannot handle hidden SSIDs.

  • The MAC address filter must be deactivated during installation. After installation, the IP can be determined with DNS (see Modbus TCP).

  • The router must be set as a DHCP server.

*With the smart-me Connection Tester (only available for Android), these WiFi requirements can be checked.

Connect the device to the cloud

  1. Check requirements

  2. Download free app for Android or iOS.

  3. iOS users must share the permission for the exact location when using the app.

  4. Connect your smartphone or tablet to the WiFi where you want to install the smart-me device.

  5. Start the app and create an account or log in with the your account.

  6. Click on "Add device" (+) and follow the instructions.

What is the technical procedure for commissioning?

Step 1: Data determination

  • The account ID is determined when logging into the app and ensures that the device to be installed sends the data to the correct account.

  • By scanning the QR code, the name of the WiFi that will later be created locally is determined by the device to be installed.

  • The WiFi SSID and password data are requested and temporarily stored in the app's local memory. When the app is closed, the cached data is deleted.

Step 2: Connecting to the temporary WiFi

  • Pressing the T1 button gives the unit the signal to create a temporary WiFi. Note: For the Pico charging station, an RFID card is used to create the WiFi (instead of the T1 button). The Pico WiFi can only be created 15 minutes after a restart (power off).

  • The smartphone must now connect to the temporary WiFi.

  • After the successful connection, it is necessary to go back into the app.

Step 3: Save data on the smart-me device

  • The app sends the collected data (account ID, SSID and password) to the smart-me device via the temporary WiFi.

  • The unit reboots and disables the temporary WiFi.

  • The smartphone reconnects to the WLAN (internet connection).

Step 4: Checking the data connection with the cloud

  • The app now waits until the first data packet has arrived in the cloud.

  • After receiving the first data package, the name of the unit can be changed and the installation is successful.

Reasons for failed installation

Requirements are not fulfilled.

  • See above for a full list of requirements.

  • Tip: The smart-me Connection Tester (only available for Android) can be used to check most WiFi restrictions.

The wrong password was entered.

  • Tip: Click Show password during installation to check the password.

The smart-me WiFi does not appear

  • With some smartphones, it can take up to one minute before the smart-me WiFi is displayed.

  • Check on the device if the WiFi is being generated:

    • 3-Phase Meter 80A Telstar and Telstart CT: The display shows a flashing reception symbol at the top right.

    • Pico: A QR code is displayed on the screen.

    • M-Bus gateway: The LED alternates between orange and green approx. 1x per second.

    • Kamstrup module: Orange LED is on (left), Red LED flashes (middle), Green LED flashes (right)

    • 1-Phase Meter 80A, 1-Phase Meter 32A and 3-Phase Meter 80A: The display alternates between a WiFi symbol with and without an exclamation mark at the top left.

  • Note: Our devices automatically deactivate the local WLAN after 4-5 minutes. This is independent of whether the installation was successful or not.

The smartphone only detects a Wifi with the name smart-me_0

  • The device is defective, please fill out an RMA application form and mention under error description: WiFi Name during installation smart-me_0

It must be ensured that the smartphone does not automatically disconnect from the smart-me Wifi.

  • Some smartphones ask whether the connection should be maintained without the Internet. This must be confirmed.

iOS installation does not continue after entering the WiFi password, the button cannot be selected.

  • The exact location must be activated.

  • "Settings" > "Privacy", and select "Location Services".

  • Select the smart-me app and activate the "Exact location" authorisation.

iOS installation does not continue after switching to the smart-me_xxxx WiFi.

  • Activate "When using the app" in the smart-me app settings.

  • Afterwards, restart the smart-me app.

  • If this does not help, the smartphone must be restarted.

The smartphone cannot connect to the smart-me WiFi.

  • This problem only affects the Kamstrup module and all discontinued products. These devices can only receive one device on their WiFi connection. It may happen that IoT devices, such as printers, connect to the smart-me WiFi and thus block access for the smartphone. As an emergency solution, a hotspot without a password can be created with another smartphone. The smart-me device must then be restarted. The interfering IoT device then connects to the hotspot without password and the installation of the device can now be continued.

Kamstrup Module

Most sources of error when installing a Kamstrup module can be identified with the LED sequence:


00:06 LEDs do not light up

00:18 WLAN is not generated

00:59 LEDs flashing fast

01:14 LED running light


How can I restart a device (reboot)?

All devices can be restarted with a power interruption.

3 phase meter: Press T1 and T2 simultaneously for 10 seconds.

Pico: In the portal top right select the cogwheel, advanced actions, restart. Only works if the pico is online.

Kamstrup modules: Remove the module from the meter, wait 10 seconds and plug it back in.

M-Bus gateway and 1 phase meters: These devices can only be restarted with a power interruption.

Can I use my device with multiple WiFi networks?

Yes, the smart-me device (except the Pico charging station) stores up to 3 different WiFi networks. You only need to install it once on each network and then the device will automatically select the network with the best wireless connection.

Can I reset the counter reading to zero?

No, as our meters are used for billing purposes, it is not possible to reset them.

Where is the WiFi password saved?

The WiFi password is only stored on the smart-me device. It is never transmitted to a server.

Are the settings and meter readings saved in case of power failure?

Yes, the unit saves all settings and values in the event of a power failure. When the power is restored, the unit reconnects to the WiFi and everything is as it was before the failure.

How can I store a new WiFi without losing the existing data?

To add another network, the unit must be installed normally. If it is not deleted from the cloud beforehand, it will not lose any energy data and configuration settings.

Can the stored WiFi information be deleted?

The WiFi information is only stored on the unit. Deleting the data can be done as follows:

  • Press the button on the smart-me device for 10 seconds. In the case of pico, the RIFD cards must be held down for at least 15 minutes after the restart (power off).

  • Connect to the smart-me WiFi with a smartphone (the name of the WiFi network is smart-me_XXXXXX where the X is the serial number of the smart-me device).

  • Connect to the IP with a browser.

  • Select the undesired WLAN, press remove and restart the device.

How do I find out the MAC address of my smart-me device?

There is no direct way to find out the MAC address. If you have a Professional licence, you can activate DNS in the advanced settings of the smart-me device and select the option Internal IP. With a ping on the DNS name, the IP can be determined, which can then be compared with the IP / MAC table on the router.

Can the mesh network be deactivated?

3-phase meters Telstar and Telstar CT create a mesh network. This cannot be deactivated.

Can I move a device from one smart-me account to another?

  • The historical data cannot be moved.

  • The unit can be installed with a new installation in another account.

With which meter reading is a smart-me meter delivered?


At what interval do the meters send data?

3-phase meter 80A Telstar, Telstar CT and Pico:

  • Every 15 minutes, i.e. at xx:00:00 xx:15:00, xx:30:00 and xx:45:00. This sends the necessary data for the load profile. This data is stored locally and forwarded in the event of a connection interruption.

  • In addition, at least every 330 seconds.

  • Then, when one of the following events occurs:

    • Meter reading change greater than 100Wh

    • Power change greater than 100W

    • Current change greater than 1A

    • Voltage change greater than 1V

    • Every second when the counter is selected in the GUI (smart-me portal)

M-Bus Gateway

  • According to the set interval, the data is read sequentially on each M-Bus meter. The reading of one meter takes approx. 3 seconds. The meters are read in the order in which they are listed under the M-Bus gateway.

Kamstrup module and 3-phase meter 80A/32A:

  • Every 15 minutes, i.e. at xx:00:00 xx:15:00, xx:30:00 and xx:45:00. This sends the necessary data for the load profile. This data is stored locally and forwarded in the event of a connection interruption.

  • In addition to this, an individual configuration can be made:

    • With Basic or Limited licences: Max. 1x per minute.

    • With Pro licensing: Max. 1x per second

1-Phase Meter 80A and 1-Phase Meter 32A

  • With Basic or Limited licences: Max. 1x per minute.

  • With Pro licensing: Max. 1x per second

What happens when I deactivate a meter?

All data already stored in the cloud is retained. After deactivation, no further data is stored. No licence costs are incurred for deactivated meters.

Can a proxy be configured on the smart-me devices?
