Hi. Just to clarify. If I were to wake up in the night and put my head down to try to sleep again do I need to stop and start the monitor? Also, if I woke up and popped to the toilet or got a drink, would I need to stop and start the monitor then too? Or does it regonise without having to touch it at all from the moment you plan to sleep, and stop from the moment you plan to STAY awake?
