Who can help me with the following, I have made an AF where the lighting should go on as soon as the light brightness (Lux) is lower than value X and movement is detected. However, the light always goes on when movement is detected. Does anyone have an idea what is going wrong? ![Foto 05-08-2024 om 16.00](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/d/8dc80b4effd46fcd1f5fe1d9414d2165271dd1e5.jpeg) ---
