In many different ways, Watts can help you create a greener everyday life. Watts bridges the gap between technological solutions and the green transition, and in this way we help you with your own green transition.

Consumption overview

The unique thing about Watts is that a budget is calculated for the expected consumption in the quarter. This allows you to adjust your consumption and hopefully avoid using more energy than expected. In this example about Energivej 8, Watts has analysed that the family will use approximately DKK 1,984 in the quarter. They are currently spending 4% below budget – and are therefore in the green.

Green: your spending appears to be lower than the budgeted amount.
Yellow: your spending appears to exceed the budgeted amount by 0–30%.
Red: your spending appears to exceed the budgeted amount by more than 30%.

Watts continuously assesses what your expected quarterly consumption will be in relation to the budgeted amount. The assessment is based on your current consumption in the quarter as well as the effects of the weather.

Green: your consumption seems to be lower than the budget.
Yellow: your consumption seems to exceed the budget by 0 - 30%
Red: your consumption seems to exceed the budget by more than 30%

Watts continuously assesses what your expected quarterly spend will be in relation to the budget. The assessment is based on your current consumption in the quarter as well as weather impacts.

Messaging service

Watts has a special messaging service for people who want to avoid their consumption increasing without being aware of it. If you have registered with Watts and added notifications, then Watts will send you a message if your consumption exceeds the value you have set.

You can choose to be notified as soon as you spend just 1% more than expected, but you can also set the limit a little higher. It's entirely up to you. You can also easily and at any time go in and change your settings in Watts. In that way, Watts becomes your very own personal energy assistant.

Holiday home owners can also benefit from this messaging service. We have examples of people who have discovered burglaries because the heating or electricity consumption has suddenly increased during a period when the house was otherwise empty!


Your budget in Watts is also called your expected consumption. When you regularly keep an eye on your actual consumption compared to your expected consumption, you can step in and change your behaviour in time. We call this intelligent advice.

Watts uses advanced technology such as machine learning algorithms to keep an eye on how your energy consumption is affected by, for example, outdoor temperatures, time of day and different consumption patterns. To calculate your budget as accurately as possible, Watts analyses your data for the last 12 months. In this way, the app can compare previous consumption and calculate what your budget for the current year will look like.

The longer you have had Watts, the more data the app has, so over time it’s also easier for the app to predict a more accurate budget. However, it is important to mention that Watts does not know your electricity or heating price, and therefore you cannot 100% compare your bills from your energy supplier with the figures that Watts shows.

Hourly rates

Your electricity price is made up of several items, and that’s something we don’t think you should have to worry about. So we’ve made it easy for you. On our graph of electricity prices for electricity from Watts, you can see the total price per kWh per hour. That is, the price includes the base electricity price, the delivery price to your local electricity grid company and taxes to the state.

You can benefit from moving your consumption to the hours when the electricity is cheapest and perhaps even greenest for the given day.

Choose green power

In Watts, you can see how the electricity is being produced right now. It is very rare that 100% of your electricity is produced by energy sources with a CO2 emission of zero. But Watts marks in green when in the day there will be the lowest CO2 emissions per kWh. It’s easy for you to see when you can, for example, start the washing machine and utilise green power. We call this climate-friendly power zones.

The bars on the Power Zones page show whether CO2 emissions are above or below the daily average.

Greenpower zone: CO2 emissions are below the day´s average.
Yellow power zone: CO2 emissions are right on the day´s average.
Black power zone: CO2 emissions are above the day´s average

Intelligent control

Watts Smart Control helps you make your home smart while at the same time thinking about the climate. You can do this by connecting washing machines or lightbulbs with built-in smart technology together with information about when the electricity is produced by, for example, wind turbines or solar panels.

If the CO2 level measured in grams per kWh is low, then you can automatically get your washing machine to start, if it can be connected to your WiFi. The solution is called Watts Smart Control, and with it you can for instance choose that your washing machine should wash clothes during the time of day when the CO2 footprint is lowest and thus have both clean clothes and a clear conscience. Watts has partnered with the IFTTT platform (standing for ‘If This Then That’), which specialises in connecting smart devices in the home, so you can start using smart WiFi products in the home based on when the power has a low CO2 footprint per kWh.

Everyone can use intelligent control in Watts – regardless of where you buy your energy.

All types of energy

Our energy assistant does not only help you with your electricity consumption. You can also connect, for example, your heating and water consumption to the assistant so that you get a comprehensive overview and complete control of your budget.

The app is open to all electricity consumers in Denmark regardless of where you buy your electricity. You can create a profile and keep track of your electricity consumption all the way down to the individual hour.

If you are lucky enough to have your district heating and water supply connected to Watts, then you can also track your water and heating consumption in the app. Alternatively, you can read your water and heating meters regularly.

Compare to others

You can compare your own consumption with others who have a home similar to yours.
Watts groups all registered homes by:
type of dwelling/ size of dwelling in m2/ number of dwelling occupants/ primary heating form/ secondary heating form (perhaps in the form of a wood-burning stove or the like)

Watts can – compared to other services – provide a very accurate comparison with other homes, since the comparison is made on the basis of current and actual data. Watts has a small challenge in comparing holiday homes, since this group is currently relatively small. But that will definitely change so that Watts can compare all housing types.

Get a unique and instant insight into your electricity consumption

With the Watts Live card you now have a unique opportunity to get a detailed insight into your electricity consumption. The groundbreaking technology is compressed into a small physical card that can easily be inserted into your electricity meter and connects to your smartphone via the Watts app.

Check your current consumption with a click on your phone and get an unprecedented overview of your household’s electricity.

Never before has the insight into your electricity consumption been greater, and it has never been easier to make active and simple changes to benefit your finances and the environment.

Solar panels

You can see how much electricity you have supplied to the grid in the given month measured in kWh. You can also see the net exchange in kWh. The net exchange is the statement that shows how much you have delivered to the grid, minus what you have consumed from the grid.

Watts does not know what your system has produced, nor does Watts know your actual consumption, because your simultaneous consumption and production are offset by each other before they ‘reach’ the meter. The graph shows how much electricity you have supplied to the grid for each hour.

The graph for solar panels shows in a very clear and simple way both the consumption and delivery to the electricity grid. The green bars on the graph show consumption and the yellow bars show the electricity delivered to the grid.
