The invention relates to a degassing unit (10) for an electronics housing, in particular for a battery, in particular for a traction battery of a motor vehicle. The degassing unit (10) comprises a main body (1) which can be connected in a fluid-tight manner with an edge of a pressure compensation opening of the electronics housing, and which has at least one gas through-opening (15) that is covered by a semi-permeable membrane (6) in a normal operating state of the degassing unit (10). The semi-permeable membrane (6) allows for a passage of gaseous media from an environment into the electronics housing, and vice versa, but prevents the passage of liquid media and/or solid matter. The degassing unit (10) can be transferred into an emergency degassing state, in which at least one emergency degassing opening (N) surrounding the membrane (6) is released. The degassing unit (10) comprises at least one monitoring means (8) which is designed to detect whether the degassing unit (10) is in the normal operating state
