Nottas will launch a device that tracks spot electricity prices at the beginning of the year.

Nottas Oy is bringing to market the first commercially available device that allows consumers an easy way to optimize the use of spot electricity at the most affordable times.

• As a result of the work of Nottas's product development team, a device and an application for controlling it were created, which allows home appliances to start when the energy price is at an optimal level, says Juha Mäki, Nottas's Chief Technology Officer. The idea for designing the device for commercial sale arose when energy prices started to rise.

• Previously, the price of spot electricity was so low that there was no need for such a meter. Now consumers are looking for the best ways to save on electricity bills. At the same time, efforts are being made to reduce electricity consumption during peak times.

The device can connect two home electrical appliances.

• For example, a water heater and underfloor heating. The system we developed starts the devices when the electricity price is at its lowest, Mäki explains. The device fetches real-time spot electricity prices from the cloud service, where they are uploaded once a day. The consumer controls the device with an easy-to-use mobile application. The application sets the desired spot electricity price level at which energy is to be purchased. The device can also be used manually. In this case, it works like a timer. Price control can also be overridden.

• With the application, you can also check if the devices are on, Mäki says.

The operating principles of the device have been developed as a team effort and production is at the manufacturing stage

• The company's product development team has calculated that the device will quickly pay for itself as an investment.

• Depending on consumption and heating method, of course, but with even a few euros of daily savings, the payback happens in a relatively short time.

• The device is controlled and monitored using a mobile interface. The application is available for both Android and iOS phones.
