Fleximax aims to remotely control household electrical appliances using FM radio broadcasting networks, a concept its backers describe as unprecedented in France. The energy-flexibility project has now entered a testing phase in the Grenoble area and could be commercialized by the end of 2026.

The idea is to use existing radio infrastructure to send control signals to connected devices in homes, helping manage electricity demand more efficiently. By tapping into broadcast networks rather than relying solely on traditional telecom or internet channels, Fleximax is positioning itself as a low-cost, wide-coverage solution for demand-side flexibility.

The project is currently being trialed in the Grenoble basin, a region often used for energy and technology experimentation. If the tests prove successful, the system could move toward market launch by late 2026, marking a new step in how French households might participate in grid balancing and energy management.

Piloter à distance les appareils électriques du foyer grâce aux réseaux de radiodiffusion de la radio : c'est l'ambition du projet Fleximax. Présentée comme « inédite » en France, cette solution de flexibilité énergétique est entrée en phase de test dans le bassin grenoblois et pourrait être commercialisée d'ici à fin 2026.
