A lot of Memphis houses — especially older brick builds — shift slightly on loess soil after long rain cycles, which can throw off the calibration of door sensors, window contacts, and motion detectors. High humidity also fogs interior camera lenses and dulls adhesive-backed mounts, causing devices to slip or fall off over time. Storm fronts rolling up the Mississippi corridor create quick voltage fluctuations, and those tiny dips can cause smart switches or hubs to reset if they aren’t on stable circuits. In neighborhoods with heavy tree cover like East Memphis, Wi-Fi dead zones pop up because wet foliage absorbs signal during humid nights. We source humidity-resistant mounts, sealed smart devices, and surge-stable components from places like Sutherlands and the Poplar Home Depot to keep installs reliable in this climate.
