A method detects the surroundings of a node, in particular in the form of a sensor apparatus and/or actuator apparatus, of a communications network. The node is capable of unidirectional or bidirectional radio communication and has a radio module equipped with an antenna, a transmit path and/or receive path, and a power supply apparatus, which is preferably energy self-sufficient, in particular a battery. The surroundings are detected, preferably at repeated time intervals, on the basis of an estimate of the detuning of the antenna of the radio module.
