   description: Maximum age of source sensor measurements stored. Setting this to a time period will cause older values to be discarded. If omitted, the number of considered source sensor measurements is limited by `sampling_size` only. Set both parameters appropriately to create suited limits for your use case. The sensor value will become `unknown` if the source sensor is not updated within the time period. A statistics sensor requires `sampling_size`, `max_age`, or both to be defined.
