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). 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-ir` is pre-packaged for IR blasters, like [Eachen IR Bridge](https://blakadder.github.io/templates/eachen_SANT-IR_01.html) or [YTF IR Bridge](https://blakadder.github.io/templates/ytf_ir_bridge.html). Choose the preconfigured `sonoff-ir` if you are using an IR blaster.
- `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.

Once you have the Tasmota IR firmware file you need, [flash it](https://github.com/arendst/Sonoff-Tasmota/wiki/Flashing) on your device using the usual method.
You can test that you have the correct firmware on your device by performing the following command in the web UI Console: `IRhvac {"Vendor":"xx"}`. The output should be a list of the supported protocols/vendors. For example:
> **RESULT = {"IRHVAC":"Wrong Vendor (COOLIX|DAIKIN|KELVINATOR|MITSUBISHI_AC|GREE|ARGO|TROTEC|TOSHIBA_AC|FUJITSU_AC|MIDEA|HAIER_AC|HITACHI_AC|HAIER_AC_YRW02|WHIRLPOOL_AC|SAMSUNG_AC|ELECTRA_AC|PANASONIC_AC|DAIKIN2|VESTEL_AC|TECO|TCL112AC|MITSUBISHI_HEAVY_88|MITSUBISHI_HEAVY_152|DAIKIN216|SHARP_AC|GOODWEATHER|DAIKIN160|NEOCLIMA|DAIKIN176|DAIKIN128|AMCOR)"}**
