Common Pain Points
▲ Long-distance control requires extensive wiring → high cost & complex installation
▲ Wired systems lack flexibility → hard to add new control points
▲ Outdoor/factory environments cause signal instability & interference
▲ Multi-device linkage → slow response, complicated pairing & debugging
▲ Equipment failures from temperature extremes or voltage fluctuations
