A communication system periodically receives contact lists from communication devices. The communication system processes the contact lists to generate a routing plan. The communication system routes incoming communications to at least one of the communication devices based on the routing plan.

Communication routing plans that are based on communication device contact lists

Systems and methods of controlling control and/or monitoring devices are provided. A controller can include a software defined radio in order to communicate with control and/or monitoring devices that employ different communication protocols. The controller can be in the form of a memory stick, memory card or dongle.

Systems and method of controlling control and/or monitoring devices

A device monitors an appliance that receives power from a source. The device includes a first coupler that couples the device to the power source. A second coupler couples the device to the appliance. A monitoring circuit is connected to the first coupler and the second coupler to monitor power supplied by the source to the appliance. A communications circuit also is provided. The monitoring circuit provides data based on the monitored power to the communications circuit for output to the first coupler. The communications circuit may include a receiver that receives a signal from the first coupler to control the monitoring circuit. The communications circuit also may include a transceiver that receives a signal from the first coupler to control the monitoring circuit and to transmit monitored power data.

Appliance retrofit monitoring device with a memory storing an electronic signature

A unit is attached to a refrigeration appliance, such as a freezer, or refrigerator, to alert the user of a sensed condition within the appliance that food spoilage may occur. The unit can monitor temperature within the compartment and determine how long until food spoilage occurs. The unit also can alert a user, monitoring service, or call a repairperson. The unit may be retrofit into existing appliances.
