Keeping the lid on electricity bills

The cloud-based OptiWatti is a smart management system for electric heating. Controlled energy use decreases the environmental burden and also saves money.

Smart energy management is an effective way to reduce a property’s energy consumption and carbon dioxide emissions. OptiWatti is suitable for homes, cottages and large properties. User comfort improves when the temperature can be adjusted in advance, also using a mobile device. The room-specific optimisation of temperatures according to needs can mean big savings in energy costs.

“The amount of savings depends on the usage of the facilities. The biggest savings are usually achieved in properties where the utilisation varies greatly. These include day care centres and accommodation facilities,” explains OptiWatti’s CEO Ari Tolonen.

Even older properties can be brought up to date by equipping them with a smart energy management system. Installation takes place without wiring  and without major renovation work. Communication between the devices is handled via wireless radio technology. Sensors measure the conditions in every room and heating is adjusted as needed. An electrical contractor authorised by OptiWatti performs the installation work.

The user experience has been carefully considered during product development.

“Although the system contains a huge amount of information, we’ve made management as simple as possible for the user. We receive a lot of feedback from users about how easy it is to use OptiWatti.”

The system is under constant development and the company listens carefully to user feedback.

“For example, customers have requested the possibility to control lighting, which is not part of the package so far.”

The system can be managed with a computer, tablet or smart phone. OptiWatti operates online so it requires an internet connection.

“If the customer has no existing connection, we can install a mobile broadband with the system.

OptiWatti utilises local weather forecasts and calculates the heating demand in advance. The system also takes electricity exchange prices into account and strives to utilise the most moderately priced hours for heating.

Energy Efficiency Expert Päivi Suur-Uski from Motiva sees a need for energy management systems like OptiWatti.

“Energy management automation should be added to every home. Not much automation is used at this time, but adjustment will become more important as the energy market changes. I believe that automation will also increase in other home appliances so that, for instance, washing machines could be turned on when the price of energy is lowest.”
