# "Complete" IR Remote Protocols # "Complete" IR Remote Protocols
The default Tasmota firmware variants include support for IR send/receive for a limited set of protocols (see [IR Remote](Commands#irremote)). Tasmota uses the [IRremoteESP8266 library](https://github.com/crankyoldgit/IRremoteESP8266) that supports numerous protocols. Each protocol consumes some program memory, especially air conditioner protocols (up to 81k of Flash size).

Each protocol consumes some program memory, especially air conditioner protocols (up to 81k of flash size). Also, every protocol included increases the time to decode the IR signal.
There are now two additional Tasmota firmware variants that provide almost all IRremoteESP8266 protocols. This requires disabling some other features to keep code size manageable.

- `sonoff-ircustom` is used if you want to customize your own firmware binary. This latter variant is required because it triggers a special compilation flag for IRremoteESP8266. - `sonoff-ircustom` is used if you want to customize your own firmware binary. This latter variant is required because it triggers a special compilation flag for IRremoteESP8266. Edit the [`IRremoteESP8266.h`](../tree/development/lib/) header in the `IRremoteESP8266-x.x.x/src` folder to disable (i.e., set to `false`) any unneeded/unwanted protocols and compile your own firmware.

## Receiving IR Commands ## Receiving IR Commands
If you have an IR receiver plugged, you will be notified each time an IR message is seen. IRremoteESP8266 will try to decode the message against all supported protocols. If unrecognized, the `"Protocol":"UNKNOWN"` will be shown. In this case, the `"Data"` field contains a hash of the received message. The hash can't be used to send the a message, but the same hash will be produced by the same message.
