Smappee is the abbreviation for "Smart App for Energy Efficiency".

You have smart meters, you have energy monitors, and then you have Smappee. Contrary to the first two categories, your Smappee is completely independent of your energy supplier. So whoever supplies your electricity and/or gas, there's no shred of opportunism in the data collected by your Smappee: they are meant for the end user's purpose only. Smappee attaches great importance to its privacy policy. Oh, and by the way: unlike the others, Smappee does not require any subscription fees. So once you bought a Smappee, you will have no further costs. To top it all of: Smappee is unique thanks to its patented technology, allowing appliance detection that provides you with an itemized bill in real-time, per day, month or year.

No. The energy and solar energy monitor, as they are being shown on our webshop, will always offer the same advantages as promised. Only the software is subject to updates, and these happens automatically. In other words: you will always have the most recent version and never be left with an outdated device.

Smappee uses highly innovative software which analyses the measured current. This is how Smappee tracks which appliances are switched on and off, and when. Find out how it works here.

Not quite. Smappee works by listening out for the energy signature left by appliances coming on and off via its clip-on current sensor installed around the incoming cable of the home. This sensor is a little like Smappee’s ear, but just like a human ear listening to an orchestra it’s sometimes difficult to hear the smaller things. Smappee is designed to help you save energy and money, so it focuses on devices that have a significant power consumption and/or are used frequently. Appliances that consume small amounts of power like LED lights or consume energy in a variable way (such as dimmers, computers, etc) can sometimes be missed by Smappee. However, we are continually improving this area of Smappee and will continually update your Smappee to ensure you benefit from the latest state-of-the-art version. Find out how it works here.

Yes. Smappee can be used on both 3x220V or 3x380V+N power installations. In this case, you will need to attach three current clamps to the cables. 

Yes, you can also see your energy consumption from a distance and check whether you really have turned off all your appliances.

Smappee provides insights into your energy consumption and helps you discover (hidden) energy guzzlers. You can take targeted action and start living more energy-consciously.  For example, you could replace an old refrigerator with a more energy-efficient model or cut down on standby power consumption at home. Various studies have shown that real-time insight into energy consumption can result into savings up to 12%.  By taking targeted action and tackling energy guzzlers, you can even reduce your energy bill with up to 30%.

When you take targeted actions, you can save up to 30% of your energy bill. For an average household, this comes down to approximately £ 150,00 a year, which means you recover the cost of your Smappee within one year.

Customer privacy is very important to Smappee. All the energy data is therefore saved in a strictly anonymous form.

Smappee has a power consumption of less than 2 watts.

If you have solar panels, Smappee also measures the electricity you produce. In addition, Smappee distinguishes between your own consumption and the yield from your solar panels. You can use the app to compare the various data. Yet another feature which makes Smappee unique! If you already have a Smappee energy monitor and you are planning to invest in a PV system, you can upgrade your Smappee with the “Smappee Exchange Package to Solar 3-phase” from our webshop, where you can find it under the tab “Accessories”.

There is no subscription fee.  The only cost is the purchase of the monitor.  The app and its updates are free of charge. Smappee even saves your data for you, as a free service :

- 5 min values : for 2 weeks

- 1 hour values : for 90 days

- day values : for 365 days

- month values : for 3 years 

As a free service, Smappee saves your data : 

- 5 min values :  for 2 weeks

- 1 hour values : for 90 days

If you want to save the registered data for a longer time, you can download them to your pc from “my.smappee.com” and consult them unlimitedly.

Smappee comes standard with 50A clamps. In a 230V system, this means 11,5 kW per phase or 34.5 kW in a 3-phase system. Optionally, 100A & 200A clamps are available, which means a power range of 138 kW in a 3-phase 230V system. In a 115V US system, the above kW ranges need to be halved. Please note that the clamps can be used up to 120% of their nominal value. Measurements will be less accurate if you overdimension your clamps. 

Please see the accessories section on the webshop for more info on the 100A & 200A clamps”

Smappee is not just a smart meter, nor just an energy monitor. A Smappee is so much more. Unlike the first two categories, your Smappee is independent of all energy suppliers. So whoever your energy supplier is, and whether or not you are considering the switch to another supplier, has nothing to do with the data collected on your Smappee. Not a shred of opportunism - and that's a promise. Smappee is a neutral energy monitor that highly respects your privacy. On top of that, it's also a one-off purchase, which means no subscription fees are involved. And lastly, what makes our Smappee so unique, is that it monitors down to the appliance level, providing you with detailed insights in your consumption behavior and costs.

The Smappee energy monitor consists of :

- 1 Smappee monitor
- 3 current clamps
- 1 power cable 230V
- 1 Comfort Plug^TM to control appliances remotely (wireless 433 MHz)   (where available)

For the Smappee monitor, you will need a Wi-Fi internet connection and a power socket. You can download the Smappee app free of charge on your smartphone or tablet (Apple iOS 7.1+, Android 4,0+). For the web version, go to “My Smappee” in the top navigation of this site.

Smappee measures the current by means of one or more current clamps which are supplied together with your Smappee. The clamp is attached to the insulated cable. As a result, Smappee does not come into direct contact with the electrical current. Even though many customers install their Smappee themselves, we recommend installation by a qualified electrician.

Contact your electrician. Smappee is so easy to install that it usually will not take any longer than 15 minutes to finish the job.

No, this is one of the unique features of Smappee. The current is measured at a single central location near the meter cabinet. It is not practical to install separate meters for each individual appliance, and in many cases this is not even possible (for example with lighting or cooker hobs).

No problem. Smappee gets installed alongside the fuse box in your apartment.

Both Smappee monitors give you real-time data on your electricity use and detect standby power consumption.  The Smappee solar energy monitor also measures the production of your solar panels.  It even gives you an exact insight into your household consumption by making the distinction between the power you get from the grid and the power from your PV system.  To guarantee correct data, it is important to use the Smappee solar energy monitor if you have solar panels. 

Indeed, with a 1-phase installation you only need 2 out of 6 supplied current clamps.  Don’t throw the remaining clamps away!  We are developing new features, that will require current clamps as well.  Stay informed by checking our Facebook page and this website regularly.

The Smappee solar energy monitor consists of :

- 1 Smappee monitor
- 6 current clamps
- 3 Y-cables
- 1 power cable 230V
- 1 Comfort Plug^TM to control appliances remotely (wireless 433 MHz)  (where available)

When you purchase a Smappee gas & water monitor, you will receive a box containing the following items:

- 1 Smappee gas & water monitor with 2 sensor inputs
- 2 batteries (2 x AA)
- 1 optical sensor (cable lenght 1 meter)
- 1 magnetic sensor (cable lenght 1 meter) 
- 3 self-adhesive mounts

No, you do not pay any subscription fees. The only cost is the one-off purchase of the device. The app and any subsequent updates are free. Smappee also stores the following data for you, free of charge: 

- Values per 5 minutes for a period of 2 weeks (5-minute values can only be created in the Smappee energy monitor if it receives the signals from the Smappee gas & water monitor);

- Values on an hourly basis for 90 days;

- Values on a daily basis for 365 days;

- Values on a monthly basis for 3 years.

The Smappee gas & water monitor takes the readings from your gas and water meters and sends this data to the Smappee app on your smartphone or tablet. You can use the gas & water monitor on its own, or in combination with the Smappee energy monitor, provided that your two monitors are installed within 10 to 20 metres of each other. For stand-alone use, you will need a smartphone or tablet that supports Bluetooth 4.0 LE. Unfortunately, the monitor does not work with digital meters.

An optical or magnetic sensor is attached to your gas and/or water meter and takes the readings from it. These are then sent to your smartphone or tablet.

Readings are taken from your existing gas and water meters using an optical or magnetic sensor. You simply place the sensor on the meter and connect this to the Smappee gas & water monitor. A flexible rubber strand makes it easy to position the monitor securely around your gas or water pipe. Unfortunately, the monitor does not work with digital meters.

You can recognise a meter that can be read with an optical sensor by the mirror on the counter. This small mirror is mostly positioned in the number 6, 8, 9 of 0. The optical reader uses the reflection of the 0, 6, 8 or 9 as it speeds past to count the number of rotations that your meter is making. In this way, it counts the number of litres of water, or m³ of gas, being consumed. You can also use the optical sensor on meters with revolving hands. In this type of counter, the hand interrupts the light beam of the optical sensor as it rotates past. In this way, the sensor counts the number of revolutions that the hand makes and therefore also the volume of gas or water being consumed. If your meter has visibly moving parts, such as hands or a mirror or wheels with a built-in cover, then you use an optical sensor.

The water meter below has rotating hands and even has a reflective surface on one of the hands. 

The gas meter below has rotating hands.

The image below shows a meter with a reflective ‘6’ on the counter.

The meter below does not have any reflective numbers on the counter, but instead has an opening in the side into which the sensor can be inserted. This kind of meter has a built-in magnet that rotates every time a volume of water or gas is consumed. The magnetic sensor senses when the built-in magnet at the end of the opening inside the meter comes past. In this way, the volume of water or gas consumed is registered. 

<Afbeelding>

You can therefore recognise meters that can be read with a magnetic sensor by the small hole below the counter on the left or right. Readings can be taken from the majority of gas metres with an optical sensor and from the majority of water meters with a magnetic sensor. Unfortunately, the monitor does not work with digital meters.

Smappee concludes that there is a leak whenever there is continuous water or gas consumption at times when this should not normally occur. You can programme the monitor’s degree of sensitivity yourself.

My gas consumption is much higher than last month. Should I conclude from this that I have a gas leak, or that my heating is no longer efficient?

Gas consumption figures should be approached with some caution. Gas consumption might rise for a number of reasons. Naturally, more gas is consumed in winter than in summer (if you have gas central heating). Winters also vary enormously. Whether a winter is harsh or mild can make a huge difference to your energy bill. Therefore, when comparing the figures, you should always take into account the outdoor temperature at the time of consumption.

Smappee offers you an insight into your water and energy consumption, which can help you to start living in a more energy-efficient way. The graphs in the app show peaks and troughs in your consumption. By studying these, you can see if you are using energy efficiently. For example, if your graph shows a rise in your gas consumption at 4 o’clock in the morning, this could indicate that your thermostat is incorrectly adjusted. Most adjustments have absolutely no adverse effect on your comfort, but can make a huge difference to your energy bill. A number of studies have shown that real-time insight into energy consumption can lead to a saving of 10% or more.

The water graphs will also provide lots of useful information. It will soon be clear exactly how many litres of water your son or daughter uses in the shower, how much water goes into a bath, and how much water you consume each day. On the app’s start screen, you can see the total consumption for the day and keep an eye on it, both in terms of litres used, and in terms of how much it’s costing you.

Over time, a whole host of useful functions will be added. The app will update automatically. Smappee will continue to be there for you, helping you to gain insight into and to save energy. 

By taking targeted measures, you can save up to 10% or more on your water and gas bills. For the average family, this translates into a saving of around 180 euros, which means that you will recoup the cost of your Smappee gas and water monitor in less than 8 months. Moreover, Smappee will protect you from unpleasant surprises in the form of invisible leaks. Ask your friends and family and you’ll be astonished to hear how many of them have had a water leak at some point. And don’t forget to ask them how many thousands of euros it cost!

Smappee attaches a great deal of importance to its customers’ privacy. All recorded data is therefore held strictly anonymously. For more information, click here

Along with your monitor, you will receive 2 AA batteries, which have a 3-year life. You can replace the batteries yourself. 

If you use the Smappee gas & water monitor in combination with the Smappee energy monitor, then you can monitor and keep tabs on your gas and water consumption at all times, wherever you are. If you use the Smappee gas & water monitor without the Smappee energy monitor, then you can always view the graphs with ‘historical data’ in the app. For new readings, you would in this case need to be close to (i.e. within a distance of around 10 metres of) your Smappee gas & water monitor, and the readings would be sent through via Bluetooth.

The Smappee gas & water monitor app works on Apple iOS (8.1+) and Android (4.4+). However, it is important to have a smartphone or tablet running at least Bluetooth 4.0 LE. You can find a list of Apple devices that support this at http://www.iphonefaq.org/archives/973945.

Yes, you will be able to use the Smappee gas & water monitor in this case too. Due to the distance however, communication with a Smappee energy monitor is generally not possible, and data transfer will therefore need to take place via Bluetooth to your smartphone or tablet. In this case, you would need to regularly go to (within 10 to a maximum of 30 metres of) your gas & water monitor and stand there for around 20 seconds. The gas and water monitor and the app will automatically find each other and exchange data. You need do no more than simply go there once a month, in order to ensure that no data is lost. This is because Smappee stores the hourly values for just over a month. Your smartphone will send the readings through to the Smappee cloud so that you do not lose them. This enables you to keep them for years.

After just a few days, Smappee will have worked out how much water you typically use for a shower, a bath, etc. Let’s say that your highest consumption in a short space of time measured by Smappee – such as, for example, running a full bath – was 150 litres of water in 10 minutes, then Smappee will take this as the benchmark value for the future. So if you were to consume more than 150 litres of water (plus a small margin) continuously, it is likely that something would be wrong.

Smappee will pick up on this and alert you straight away. NB: this feature only works in combination with the Smappee energy monitor, because this can contact you and alert you via Wi-Fi and Internet.

Whether you should buy a Smappee home energy monitor or a Smappee Pro, depends on your expectations regarding registration and analysis of your energy data. 

Smappee Pro is the best choice if you:

• want to  measure the consumption of separate circuits and subcircuits
• want to know how much each separate phase of your installation consumes
• want to measure active as well as reactive power
• consume more than 100 kW 
• want to have one single energy management system for different locations

Some differences :

• The Smappee Pro has 9 current inputs, the energy monitor 3 or 6.  Each input can be either consumption or production (e.g. solar) and can be configured as either single or three phase. 
• Disaggregation on each input : Smappee's unique ability to detect and measure appliances is working on each CT connected to the Smappee Pro.
• The Smappee Pro has 3 instead of 1 phase voltage reference, to allow for highly accurate power measurements.
• The Smappee Pro registers richer data, monitoring totals and per phase for kW, kVar and Volts.
• Communication: Ethernet port as standard. A WiFi dongle or 3G/4G modem can be attached to the USB port.
• In addition to the app, the Smappee Pro data is accessible via the web portal where the rich data from all your Smappee Pro (and residential Smappee) can be analysed in one place. 
• As opposed to the Smappee energy monitor, there is a subscription fee for the Smappee Pro.

Yes.

The Smappee Pro has a USB port, to which you can connect a WiFi dongle or a 3G/4G modem (future SW release).

50 Amp, 100 Amp, 200 Amp, 400 Amp, 800 Amp.  The last 2 can only be used with the Smappee Pro, the others also with the home energy monitor.

Yes. API documentation can be sent to you on request.

The Smappee Pro records processes and stores a lot of rich consumption data. The Smappee license grants/provides access to this data via the pro.smappee.net portal and the API.

There is no limit as long as the Smappee Pro license has been purchased to cover the period of data requested.
