The Next Web writes that 1KOMMA5° was founded almost two years ago in Hamburg and its main product for the market is Heartbeat, an IoT device which optimizes energy use in your home and if you have solar panels or an energy storage solution, that's even better.

Heat pumps and car chargers benefit from the system, as well and by using Heartbeat, company officials claim that you can cut energy-related costs, while also reducing the stress on the grid.

Such systems, if implemented at large scale, can help us achieve our climate goals and reduce energy-related emissions.

What's interesting about Heartbeat is that it can automatically detect when cheap energy is available, such as the one coming from renewable sources, like solar or wind. At that given time, it will make the purchase, ensuring that you constantly have access to clean and cheap power, depending on your needs.

Also, if you have a solar system, for example, which you use to sell excess power back to the grid like prosumers do, Heartbeat can detect when it's the best time to sell the energy, so that you get your money's worth in the transaction. This works best assuming you have a battery storage solution on hand.

On average, company officials claim that Heartbeat was able to save homeowners around 1.550 euros over the course of a year through optimizations.

Founder and CEO Philipp Schröder said that "the 1.5° climate target needs speed in execution and with this round we are delivering our contribution to make as many buildings CO2 neutral as quickly as possible."

Last year, Porsche and the Norrsken Foundation were among those who invested a total of 200 million euros in the solution proposed by this startup.

The latest 420 million financing round will be used to make Heartbeat even smarter and compatible with even more energy devices, as well as to scale the company's research and development capabilities, with a new center in Berlin.
