The invention relates to an electrical active assembly for generating a physical effect such as heat, cold or humidity, and a textile assembly, such as a clothing assembly, including said electrical active assembly, with an application to a system for regulating the temperature or humidity of a user's body. The electrical assembly comprises a first textile support, a first active element 1 for generating the physical effect, connected to a power source, and located on or in the first textile support, a first sensor 2 for sensing data relative to a physical information, such as temperature or humidity, connected to a power source, and located on or in the first textile support, and a first controlling unit 3 connected to the first active element and sensor, and located on or in the first textile support, such as to allow the activation/deactivation by the first controlling unit of the first active element depending on data sensed by the first sensor. The electrical assembly also comprises a second textile support distinct from the first textile support, a second active element 4 for generating said physical effect, connected to a power source, and located on or in the second textile support, a second sensor 5 for sensing data relative to the physical information, connected to a power source, and located on or in the second textile support, and a second controlling unit 6 connected to the second active element and sensor, and located on or in said second textile support, such as to allow the activation/deactivation by the second controlling unit of the second active element depending on data sensed by the second sensor. The first controlling unit is connected to the second active element and sensor, such as to allow the activation/deactivation by the first controlling unit of the second active element depending on data sensed by the second sensor and/or by the first sensor, and/or the second controlling unit is connected to the first active element and sensor, such as
