美国采购需求：电子、照明

I recently purchased a wireless light switch and receiver kit that claims to handle high power without the need for wiring. Unfortunately, the performance has been inconsistent. While it sometimes responds to a single press, there are occasions when I have to try multiple times for it to work. I attempted to re-program the system as suggested, but the issues persist. It's crucial for the device to operate reliably, especially for controlling lights and fans. Could you provide insights or solutions on this matter? Thank you!
