And all of this without lock-in, without subscriptions, without artificial limitations. Instead, you get lifelong, free updates that keep your system always up to date.
Through optional, one-time purchasable FEMS Extension Apps, you can expand your system at any time – for example with charging stations, heating rods, or other consumers.
