Note:
1. Our product needs to be used with a receiver; unless you have previously purchased our product and need to purchase additional accessories, otherwise purchasing a transmitter or receiver separately will not work.
2. Our product uses RF433 communication, but it cannot be mixed with other RF433 products because, in addition to frequency, it also needs to meet the requirements of decoding and coding speed.
3. Due to the significant shielding effect of metal on wireless signals, please do not attach the transmitter to metal doors such as iron doors, anti-theft doors, fire doors, etc. In addition, the receiver should not be obstructed by metal plates.
If you find that the response distance is too close, please be sure to check if there is any metal affecting the signal transmission and reception of the product.<\/p>\n
