A temperature monitoring service in which remote monitoring units are distributed to customers who then set up monitoring as desired at their facilities. The devices may be registered through a web site using the Internet. Monitoring information may be communicated using a publicly available, wireless network, such as a cellular telephone network. The service may be provided with a system, including a server, architected to allow each remote monitoring unit to be simple and low cost. Similarly, the system may be architected to allow monitoring and control information to be communicated reliably, but at low cost. The server, however, can deliver high levels of monitoring functionality. The server may support using a variety of analytical methods to process the monitoring information, including analyzing the rate of temperature change at a monitored facility.
