What Matters for This Task
Nursery monitoring should stay simple enough to use consistently. A stable, inaccessible-to-children location and clear interpretation matter more than a crowded app screen. Environmental readings can document the room, but they do not diagnose a child’s health or establish a guaranteed safe sleeping environment. Choose the measurements that answer an actual room question.
