This invention relates to a retractable and extendable awning and a control system for automatically extending and retracting the awning. In a retractable fabric awning a front of the awning fabric is attached to a movable front bar, movably mounted at the wall of a building by retractable arms. The rear of the fabric is unrolled from a roll of the fabric on the building wall when the arms move the front bar away from the building. The awning features a weather sensor unit on its front bar. The weather sensor unit can detect excessive wind and mechanical shocks and also sunlight and rain. The sensor is in wireless (via radio frequency) communication with an indoor control unit which can automatically retract the front bar during windy, rainy and/or low sunlight conditions and extend the front bar during calm and sunny conditions.
