A home system includes a server having a first wireless communication port, and a plurality of devices, such as sensors. Each one of the devices includes a corresponding second wireless communication port. One or more of the devices is a timer/reminder sensor device associated with an object of interest. The timer/reminder sensor device includes a timer mechanism having a time input and an output. The timer mechanism is associated with the object and is adapted to input a time interval from the time input, time for the time interval and then responsively output to the output. The timer mechanism communicates the time input and the output of the timer mechanism between the second wireless communication port of the timer/reminder sensor device and the first wireless communication port of the server.
