smart-me devices

What WiFi standards are supported?

The smart-me device supports 802.11 b/g/n with 2.4 GHz.

5 GHz networks are not supported.

What ports have to be open?

The smart-me device requires port 80 UDP and port 53 for DNS.

Is the energy and power measurement accurate?

Of course it is! This is without a doubt one of the most accurate energy and power meters available. We guarantee a maximum error rate of 1% over the entire metering range (0.1–3,680 W). Each device is calibrated during production for maximum accuracy.

Will the settings and meter readings be saved if the power fails?

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

Can I use my device in multiple WiFi networks?

Yes, the smart-me device stores up to six different WiFi networks. You only need to install it once on each network, then the device will always automatically select the network with the best wireless connection.

How much data traffic does a smart-me device generate?

On average, the data volume is 50 MB per month, per meter. If the meter is accessed frequently, the data volume can be as much as 150 MB/month.

With the three-phase meter (and the single-phase meter with LCD), you can change the internal upload, which affects the required data traffic. To change the guideline values:

  • At 60 s: 50 MB/month

  • At 30 s: 71 MB/month

  • At 10 s: 153 MB/month

  • At 5 s: 279 MB/month

  • At 1 s: 1,279 MB/month

Can I reset the meter to zero?

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

What is the power factor reading?

The power factor is the amount of active power relative to apparent power. This value is between 0 and 1.

  • If only reactive energy is consumed (for inductive loads such as motors or transformers), the power factor is 0.

  • If only active energy is consumed (with resistive loads such as incandescent bulbs or heaters), the power factor is 1.

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

To get a MAC address smart-me device’s you need to access the device itself or its ‘website’. This example shows a smart-me plug, but the principle is the same for all smart-me devices.

  • Hold down the button on the plug for 10 seconds

    • The plug’s light alternates between orange and green

  • Connect to the WLAN of the smart-me device with your laptop/tablet.

    • The WLAN name is smartme_XXXXXX, where X is your smart-me device’s serial number

  • Open your laptop/tablet browser and go to the page 192.168.1.1

smart-me Cloud

Where can I change my login password / email address?

To change your login password, go to smart-me.com and log in with your existing user account. Click on your user name (top right) and select Settings. Click on Change Password.

If you can't remember your password, it can be reset using the forgotten-password-function. For this, however, a valid e-mail address must have been used when creating the account.

How can I delete my smart-me account?

You can delete your smart-me account as follows:

  • Log in to www.smart-me.com with your account.

  • Click on your user name (top right) and then on Settings.

  • Click on Delete user

Why do unknown counters appear in my account?

Basically, the smart-me Cloud only displays meters in your account if the data for them are transmitted to it. If a meter appears that you do not know about, this may be because a meter connected to the gateway is configured to send other meters (e.g. some heat meters).

Some L+G meters are also configured in such a way that they also send a water meter, for example, which is then displayed on the smart-me Cloud.

If you try to delete these meters, they will most likely reappear. For more information, see Why does my deleted meter reappear in the cloud?
To avoid paying the licences for these unused meters, you can deactivate them. You can find out more about this under How do I deactivate my meter?

If working with API meters, the external configuration should be checked.

Why does my deleted counter reappear in the Cloud?

If a meter is deleted in the Cloud, all its data is deleted in the Cloud. If this meter sends data to the cloud again after the deletion process, the cloud recreates the meter (including a new meter ID). However, the meter's past measurement data is irretrievably deleted. If/then actions or settings in billing also do not refer to the "new" meter and would have to be reconfigured accordingly.

The following points can prevent the meter from sending data to the cloud again and thus being recreated:

  • Install the meter in another account where it can then send the data.

  • Do not supply the meter any more. As soon as the meter is powered and has an internet connection again, it will send the data to the cloud again.

  • Delete the WLAN from the meter. The meter can no longer send data without the Internet.

Alternatively, you can deactivate the meter in the Cloud. A deactivated meter does not need any licences and you can reactivate it at any time and access its data.

How do I deactivate my meter?

To deactivate your meter, please proceed as follows:

  1. Log in to the smart-me portal.

  2. Click on configure

  3. Click on Meter/Folder Configuration

  4. Select the meter you want to deactivate

  5. Click on Edit Node (green button at the top)

  6. Remove the tick from Meter active

  7. Click on Save

Alternatively, you can also drag the meters all into one folder (e.g. "deactivated meters") and deactivate all meters at once by right-clicking on the relevant folder, Mass Actions, Deactivate All Meters.

Note on deactivated meters: A deactivated meter no longer costs a licence, but you can also no longer access the past data of the counter as long as it is deactivated. During the time the meter is deactivated, no new measurement data of the meter will be saved on the Cloud.

How can I set the correction factor on the Cloud?

To set the correction factor of a module or meter, please proceed as follows:

  1. Log in to the smart-me portal.

  2. Click on configure

  3. Click on Meter/Folder Configuration

  4. Select the relevant meter

  5. Click on Edit Node (green button at the top)

  6. Enter the correction value at Value correction. (Attention: only for Value Correction, not for Parent Folder Value Correction)

  7. Click on Save.

What happens to my load profile data in the event of a connection failure?

If the meter no longer has a connection, the data is stored in the data logger every 15 minutes. When the meter has an internet connection again, the data is uploaded to the cloud again. The meter only stores the 15-minute values locally for about 2 months, but the meter reading is always stored. This means that if the meter is connected again after e.g. 3 months, the displayed meter reading is correct, but the load profile data can only be displayed from the last two months.

Security

Is the connection secure?

Yes. Not only is the WiFi connection encrypted; all data sent from or to the smart-me device is encrypted too. Each device uses an individual password for maximum security.

Where is the WiFi password stored?

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

How can I delete the stored WiFi information?

The WiFi information is stored on the device itself. Therefore, the device itself must also be accessed in order to delete the data. To delete the data, please proceed as follows:

  • Hold down the button on the plug for 10 seconds

    • The plug’s light alternates between orange and green

  • Connect to the WLAN of the smart-me device with your laptop/tablet.

    • The WLAN name is smartme_XXXXXX, where X is your smart-me device’s serial number

  • Open your laptop/tablet browser and go to the page 192.168.1.1

  • Select the WLAN and click on "remove".
