 ===== RF-Remotes =====
-Radio remotes, used for example for remote lamp switches use similar protocols as IR-Remotes, in some cases the actually reuse the same protocols. To be able to use these protocols we need a radio receiver which decodes the RF-signal.

-In Europe, the most common frequency used is 433.92MHz. This frequency is for example used by X10, Nexa, Detronic, WaveMan. It is possible to buy receiver chips for this frequency, but the cheapest and easiest way is actually to buy some cheap device which use the protocol and "hack" the receiver. Then you get receiver, case and battery holder for the same price as a receiver card. A typical example is the [[:modupm|UPM-unit (see here)]]
