Certain embodiments of the disclosure can include methods, devices, and systems for locating an electronic signal sent in a large, enclosed space, including hotels and offices. The embodiments can include initiating a signal from a location within the large, enclosed structure triggered by, for example, atmospheric conditions or user input, among other triggering mechanisms. The signal can then be transmitted via low-energy, low-cost network devices placed efficiently throughout the building. Devices within the network read the message signal and efficiently continue its transmission through the network. When received by a display device, the message can be identified by its originating location and mapped against a layout of the building.
