Sensing and metrology in the presence of environmental noise represents a considerable challenge because the noise limits the observation time and hence the achievable precision. In this work we explore the idea what may happen when we have limited access to the environment, e.g. we can measure whether the sensor has spontaneously emitted a photon. This information alone may improve the achievable precision quite considerably and the present work shows this at the hand of some examples.
