The present invention relates to operating an RF system () comprising multiple nodes () for transmitting and/or receiving RF messages (). RF messages transmitted by a transmitting node () are received at receiving nodes (). It is determined whether the RF messages were completely received. Upon missing at least part of the RF messages at the receiving nodes, it is determined whether missing of at least part of the RF messages is caused by an activity event of a tangible entity () in transmission paths () between the transmitting node and the receiving nodes based on one or more RF system criteria. The RF messages () may include RF-based sensing messages () and RF data messages (). A discrepancy between missed parts of the RF-based sensing messages and missed parts of the RF data messages may be determined and included in the RF system criteria.

Upon detecting that the single-channel confidence level () is above a first single-channel threshold level () and below a second single-channel threshold level () which is higher than the first single-channel threshold level (), a multi-channel communication technology () for performing radio frequency based sensing is selected based on one or more radio frequency system criteria, and radio frequency based sensing is performed by the multi-channel communication technology ().

A method for automatically creating lighting settings based on an image or images. An event associated with such images can be detected, such as the uploading of a number of photos to a gallery, or the posting of an image on social media. By assessing the event, and the image or images, it is possible to determine whether and how to create a new lighting scene. If multiple images are present, it may be possible to group or merge the images to downselect to one or a small number of images, or image parameters. The lighting scene or scenes can then be created based on these images or parameters. For example, a scene can be created to mimic the colour palette, or even to attempt to mimic or reflect shapes or distributions of light or colour in the image.
