Here’s how to convert a wireless doorbell from HomeDepot to close a relay instead of chiming…This whole thing started from a MAKE forum discussion! “With the addition of one capacitor, one relay, and a small piece of wire we can convert an inexpensive wireless doorbell into a remotely controlled relay useful for a wide range of applications. These include remote PC starting, lighting control, Halloween effects control, or virtually anything that can be controlled by a pair of relay contacts.”Link.
