The companies Loxone, specialising in home and building automation, and sonnen, dedicated to energy storage, have announced a new technological partnership that will enable automated optimisation of solar energy use in both residential and commercial buildings. This integration will allow energy consumption in a building to be intelligently coordinated based on various factors such as solar production, weather forecasts, and dynamic electricity tariffs.

This integration will be made possible through Loxone’s Miniserver and sonnen’s intelligent storage systems. The energy stored in sonnen batteries can be managed autonomously by Loxone’s control system, prioritising self-consumption and adjusting the operation of heating and cooling systems, lighting, blinds, or appliances according to real-time needs, without user intervention.

Key features of this solution include the automatic activation of HVAC systems when there is a surplus of solar production; prioritisation of electricity use when batteries are fully charged; reduced consumption in anticipation of low solar generation; and dynamic energy usage adjustment based on occupancy, time of day, or grid conditions.

“Smart home technology enables the automated management of energy self-consumption, controlling photovoltaic production, energy surpluses, battery charging (including solar batteries or electric vehicle chargers), and overall building consumption,” explains Meritxell Esquius, Head of Marketing at Loxone. She also highlights the energy use optimisation provided by the solution: “The system activates consumption based on solar surplus or predefined criteria, such as periods of lower electricity rates or user-defined consumption priorities, with real-time monitoring,” she adds.

The collaboration between the two companies reinforces the role of automation and energy storage as key elements for energy efficiency and the transition to more sustainable models. It represents a significant opportunity for developers, integrators, and end users seeking to increase the energy independence of their buildings.

“This alliance enables us to offer a high-quality, all-in-one solution for the intelligent management of buildings with energy storage. The direct integration with sonnen batteries facilitates optimised self-consumption, reduced dependence on the electricity grid, and dynamic adaptation to production and demand conditions,” concludes Esquius.
