Review on π Wireless RF Relay Remote Control Switch, QIACHIP 12V 1CH 433Mhz Momentary Light Transmitter with Receiver (1 Relay) by Joe Patterson
Works great for electric door lock
I have an electronic door lock that unlocked via pushbutton, and wanted to improve the system with a keychain unlock feature. This worked perfectly. The key fobs are easy to program and pair with the relay. It supports normal open, normally closed, and flexible options for holding the connection for different durations. It's one of those devices you can set-and-forget - perfect for hidden systems you want to just "work" without constant tinkering.
- With the ability to control lights and appliances remotely, this wireless relay switch offers a convenient way to manage your home or office lighting and electronics
- The remote control may be affected by electromagnetic interference
