SENSOR
Voltaware single and three-phase sensors are a revolutionary approach to smart metering technology for residential units. The sensors are DIN-rail mountable, which make the installation straightforward and permanent. They are capable of connecting to Wi-Fi (IEEE 802.11 b/g/n) wireless access points. After the quick and easy installation, they automatically start transmitting electrical measurements over a secured communication network, with minimum maintenance requirements. The communication to the Voltaware cloud is secured by the client-validated transport layer security (TLS) v1.2 protocol, which is the industry-standard security protocol.
Our sensor is non-intrusive and very simple to install. Since it is self-powered with magnets, no power cable or batteries are needed. In addition, our system is event-based rather than time-based, which means that, depending on your settings, you'll receive an alert every time something happens. Our event-based sensor provides a very accurate reading with a standard deviation of no more than 1-2% from the actual values. Most importantly, we provide the most economically viable solution of its kind on the market.
As soon as the sensor is installed in the fuse box, it samples voltage and current more than 10,000 times a second, providing a very high level of granularity. The data is then sent to the Voltaware cloud and available for integration through API into the customer-facing products (mobile application, web application, etc).
Voltaware is not available for direct consumer purchase. It is currently only available through our trusted network of utility and ecosystem partners. If you are a utility, please see "our offer for utilities".
If you are a business interested in providing Voltaware to your customers, please contact us at enquiries@voltaware.com .
The Voltaware single and three-phase sensors are easy to install with minimum disruption to your supply. The current transformer (CT) is placed around the phase cable and the voltage probes are magnetically attached to the corresponding circuit breaker connectors; it can also be hard-wired into the breaker terminals. The sensor is small enough to fit unobtrusively inside most fuse boxes, and it is non-intrusive so a professional electrician can install it without having to inform your energy provider.
If you need any help with the sensor installation, please refer to the support materials section here.
The single phase sensor has a single clamp measuring 30A and the 3-Phase sensor has three clamps measuring 100A. The single phase sensor measures single phase voltage and current, but the three phase sensor measures three phase voltage and current in Y connection mode with neutral.
The sensor installed in your fuse box depends on the country where you are located and on your electric installation. If you are unsure about it, please contact a professional electrician who will help you figure out which sensor you need. Single phase cabling is most often used in residential places.
In case you have any doubts or questions, please contact the utility directly from which you have received the sensor. If you have obtained it from Voltaware, please send an email to support@voltaware.com with your sensor ID and using your registered email address.
The sensor power consumption is less than only 1 Watt, which is the equivalent of approximately 0.72 kWh per month.
The sensors have the European Union (EU) safety certificates to operate across Europe. For other certificates, you can refer to the specific product page.

The sensor is able to save the last 16 events when there is no internet connection. The energy consumption and production values however will be kept forever, until manually reset. However, disaggregation for that period will be lost.
The single Phase sensor can monitor 1 circuit using one clamp while the three-phase sensor can monitor 1, 2 or 3 circuits.
No, the sensor doesn't have an option for an ethernet port. It must have a constant and stable Wi-Fi connection.
The single phase needs to be clamped to the main current cable; while the Three-Phase needs to have at least one clamp on the main. The remaining two clamps can be connected to other appliance circuits.
The sensor works in an event-based manner, i.e. it will send an event every time there is a change in the RMS value of the current greater than 200mA. The sensor also sends time-based information every minute.
Yes, the sensor can be installed on any AC powered line. Solar panels are connected to an inverter that converts DC voltage to AC. Therefore, our sensor can only be installed on the output of the inverter. Depending on the installation, it can measure imported energy, exported energy, or both at the same time.
The information set is similar to any other power circuit. Voltage, Current, Power, Power factor, Voltages Harmonics, and Current Harmonics are the electrical quantities transmitted by the meter.
Our sensors can send electricity data directly to your servers. For more information, please contact enquiries@voltaware.com .
Yes, Voltaware sensors will not interfere with any third-party smart meter. Furthermore, depending on the meter data measurement resolution, we can enable data services on the already installed smart meters. If the resolution is high enough, utilities can integrate smart meter data into our data analytics platform to enable disaggregation and a combination of energy efficiency and smart home features. You can find out more here .
Yes, the Voltaware sensor can work in any country. The sensor you need depends on your fuse box. Our Single-Phase sensor has a single clamp which is suitable for Single-Phase installations and our Three Phase sensor has three clamps which are suitable for Three-Phase installations. For further information please consult the product page.
Typically around 12MB per month for the Single-Phase and three times more for the Three Phase sensors.
The sensor can be used in retail and real estate to monitor large buildings, petrol stations, SMEs, shops, restaurants, etc. If you would like to know more about this, please check our website for businesses here .
Your data history is continuously stored in our cloud. However, if you would like to have it deleted, please contact the utility directly from which you have received the sensor. If you have obtained it from Voltaware, please send an email to support@voltaware.com using your registered email address and we will delete all your personal data.
