Common Pain Points

*Long-distance control requires extensive wiring → high cost and complex installation

*Wired systems lack flexibility → difficult to add new control points

*Outdoor and factory environments cause signal instability and interference

*Multi-device linkage → slow response and complicated pairing/debugging

*Equipment failures due to extreme temperatures or voltage fluctuations
