Technologies directed to interactive physical placement of devices for optimal motion sensing using channel state information (CSI) are described. A method includes determining that a size of received CSI data exceeds a first threshold or is received in a specified time interval, the CSI data representing channel properties in a wireless network of devices. The method further includes validating a physical placement of the wireless devices by i) determining that a parameter value associated with the CSI data is less than a second threshold representing a no-motion condition and the first CSI data matches ground truth data associated with the no-motion condition; or ii) determining that the parameter value is greater than a third threshold representing a motion condition and the first CSI data matches ground truth data associated with the motion condition. The method sends to a user device an indication that the physical placement is validated.
