The HEMSlogic Gateway offers next-generation energy management for the home of the future. With data-driven, self-learning algorithms and a predictive approach, energy management is elevated to a new level. Cross-manufacturer compatibility with heat pumps and wall boxes ensures broad compatibility and creates synergies. The reduction of grid fees is achieved by meeting the requirements for connecting controllable consumers according to EnWG § 14a. A user-friendly app allows for the management of all existing and new energy systems within one platform. The measurement and visualization of energy production and consumption provide concrete insights into self-generated energy, distribution to consumers, and consumption within the home network. The optimization of self-consumption and the increase of grid independence are achieved through direct and automatic control of devices based on data-driven algorithms. Cost savings are realized through predictive optimization compared to an unmanaged home, as well as by reducing the CO² footprint. The control and shifting of loads such as electric cars and heat pumps eliminate the need for larger grid connections without compromising home comfort. Through "Over-the-Air" software updates, the system is future-proof and expandable with new features such as dynamic tariffs. The power supply is 230 VAC 50Hz, with a self-consumption of 3W. Installation is on a DIN rail, with 4 modular units, a width of 71.6 mm, a depth of 69.4 mm, and a height of 89.7 mm. The operating temperature ranges from -5°C to +55°C, and the relative humidity is 25-90%. The product complies with CE, RoHS, and REACh standards.
