 Tasmota uses the [rc-switch library](https://github.com/sui77/rc-switch/) to decode RF codes. Supported hardware depends on rc-switch library support only.
 
 ## Sending RF Codes
-Send an RF control code as a decimal or hexadecimal string in a JSON payload. An inexpensive RF receiver such as a [STX882](https://www.nicerf.com/productslist_119_stx882.html) can be connected to a device running Tasmota. In order to send RF data you need to _**configure the connected GPIO as `RFSend (105)`**_
