So my daughters sensor was on for a week and due for a restart. I stopped and started the sensor and before the 2 hours was up, she went over to a neighbor's house and left the receiver at home. So now its had signal loss for an hour. DO I just "stop sensor" and then start it up again once she gets home? or are you not able to stop and start more than once? Or should I just wait till she gets back in range and see what it does?
