A system for monitoring integrity of a structure includes at least one sensor module and a gateway. The gateway receives data packets from the sensor module(s) and periodically pushes the data packets to an offsite system without receiving a request from the offsite system. Additional data packets may be transmitted on request. The system may include a solar power supply. The system may include a communication module to transmit data packets over a communications link. The communication module may have a dynamic IP address. The communication module may remain in a standby state until additional information is received from the gateway. A method for monitoring integrity of a structure includes determining a power failure and pushing a packet to the offsite system indicating the power failure. A method for monitoring integrity of a structure includes determining an event and transmitting a data packet corresponding to the event.
