In this article, you’ll learn how to monitor your energy consumption via your smart meter using your smartphone. There are several independent app providers that allow you to gain insights into your usage. One of the longest-standing suppliers of WiFi P1 meters is Smart Gateways, a Dutch company that offers a dongle (also known as a Gateway). You connect this Gateway to the P1 port of your smart meter, which looks like an old-fashioned telephone connection, allowing real-time consumption data to be transmitted. Smart Gateways comes highly recommended by many companies and users around Europe and has a Trustpilot rating of 4.9 out of 5.

This energy consumption manager enables you to track your energy usage in real time. You can view beautiful graphs showing energy consumption and solar panel feed-in per hour, day, month, and year. Gas consumption is also clearly visible. In Belgium, you can even monitor your water usage if you have a Fluvius water meter.

Is my smart meter suitable for reading energy usage via a smartphone?

All smart meters in the Netherlands, Belgium, Sweden, Denmark, Finland, Hungary, Ireland, Lithuania and Switzerland can be read using the WiFi P1 meter from Smart Gateways. More countries are added in the future. You can even use the WiFi P1 meter without power if you have a new smart meter. On this page, you’ll find an overview of various smart meters and whether you need a USB adapter. Smart meters that can be read include brands like Iskra, Kaifa, Kamstrup, Landis+Gyr, METCOM, Sagemcom, Siconia, and ZIV.

How often does the smart meter send data?

There are different versions of smart meters. Only the newest smart meters of the DSMR5, ESMR5, or SMR5 type send data per second. However, smart meters of the DSMR2 and DSMR4 type only send data once every 10 seconds. You can usually find the DSMR version on the smart meter itself. In most countries other than the Netherlands, smart meters send data per second because they are DSMR5 meters. If you need more information, consider reaching out to your energy supplier.

Which data does a smart meter transmit?

Smart Meters transmit the following data:

  • voltage per phase (only for DSMR5 meters)
  • current per phase (only for DSMR4 and 5 meters)
  • consumption per phase (only for DSMR4 and DSMR5 meters)
  • feed-in per phase (only for DSMR4 and DSMR5 meters)
  • gas consumption (only in the Netherlands and Belgium)
  • water consumption (only in Belgium)
  • total consumption and production for peak and off-peak rates
  • total consumption for gas and water

Old smart meters, such as DSMR2 and DSMR4, do not provide all the required data. For instance, a DSMR2 meter does not provide information about individual phases, even in a 3-phase connection. On the other hand, a DSMR4 meter does not provide data about voltage.

How can I see the output of my solar panels?

With the WiFi P1 meter, you can also see how much energy you are feeding back into the grid if you have solar panels. This information is continuously provided by the smart meter via the P1 port, keeping you informed about your net energy generation and consumption at all times.

Can I connect my solar inverter to the smart meter app?

If you have a SolarEdge inverter, you can easily connect it to the Energy Dashboard of Smart Gateways. You only need a pairing code, which you can generate using the SolarEdge smartphone app. The dashboard provides clear instructions on how to do this, making it easy for everyone to follow.

What do you need to read a smart meter via the P1 port using an app on your phone?

To monitor your energy consumption via your smartphone, you need the WiFi P1 Meter from Smart Gateways. This energy consumption manager with a dashboard is available at their website. The WiFi P1 Meter (gateway) is offered in versions with or without a screen. The dashboard functionality remains unaffected by the version of the gateway you choose.

Can I connect multiple devices to the smart meter if my P1 port is already in use?

If the P1 port of your smart meter is already in use, for example, with a load balancer from a charging station for your car, opt for the Smart Meter Gateway with Active P1 Splitter. This WiFi P1 meter includes a built-in active P1 splitter. Connect the IN port using the provided cable to the smart meter. Connect the current device to the OUT port of the gateway. When you connect something to the OUT port of the gateway, the gateway consumes slightly more power. Therefore, you need to connect a separate power supply to the USB port of the gateway. This power supply is also available in the Smart Gateways webshop.

I have purchased the WiFi P1 meter. How can I view energy consumption on my phone?

After placing your order, your package containing the WiFi P1 Meter will be shipped. You will receive an email with an activation link within one working day. Use this activation link to log in to the dashboard. On your phone, it will look like this:

My solar panels sometimes switch off by themselves, what causes this?

If too much electricity is generated in the neighborhood, the electricity grid may struggle to manage it properly. This can cause the voltage to become too high. When the grid voltage exceeds 253 volts, solar panel inverters automatically shut down. Inverters are devices that convert the electricity generated by solar panels into a usable form for your home. They are designed to shut down automatically to prevent issues and maintain safety when the voltage is too high.

Can I see when the voltage in my neighborhood is too high and the inverter shuts down?

Through the ‘Advanced’ button, you can view the voltage and consumption per phase of your smart meter. If the voltage exceeds 253V, it’s likely that your solar panel inverter will automatically shut down for safety reasons. If this occurs frequently, you can contact your grid operator. They may be able to make adjustments to the neighborhood transformer to resolve the issue.

WiFi P1 Meter – Voltage and power usage per Phase


In this article, you’ve learned how to monitor your energy consumption using your smartphone via a smart meter. Various independent app providers offer insights into your usage, and Smart Gateways, a reputable Dutch company, provides the WiFi P1 Meter (also known as a Gateway) for this purpose. This device connects to the P1 port of your smart meter, resembling an old-fashioned telephone connection, to transmit real-time consumption data. Smart Gateways is highly recommended across Europe, boasting a Trustpilot rating of 4.9 out of 5.

This energy consumption manager allows you to track usage in real-time with detailed graphs displaying energy consumption and solar panel feed-in by hour, day, month, and year. It also displays gas consumption, and in Belgium, water usage from a Fluvius water meter can be monitored.

Smart meters across several countries, including the Netherlands, Belgium, and others, are compatible with the WiFi P1 meter from Smart Gateways. Newer smart meters transmit data per second, while older types may transmit data less frequently. For more specific information, consult your energy supplier.

If your solar panels intermittently turn off by themselves, it may be due to excessive voltage in the neighborhood causing inverters to automatically shut down to prevent damage. Monitoring the ‘Advanced’ settings of your smart meter can help you identify such issues, prompting you to contact your grid operator if necessary for adjustments to the neighborhood transformer.
