BLU Motion LUX sensor values in an interval

The Shelly motion sensor 1 and 2 does give LUX values in an interval which you can read via a scene and set an action at a certain value. However the Shelly BLU Motion does not work like that I found out. It only gives you a value when it detects motion. Is it possible to change that way of working the same as the Shelly motion sensor 1 and 2? Or will that drain the battery?
