# Universal Remotes {#universal_remotes}
|
|
|
|
## Televisions
|
|
|
|
Adding your TV set to the universal remote is quite straightforward. Up to 6 signals can be recorded: `Power`, `Mute`, `Vol_up`, `Vol_dn`, `Ch_next`, and `Ch_prev`. Any of them can be omitted if not supported by your TV.
|
|
|
|
Each signal is recorded using the following algorithm:
|
|
|
|
1. Get the remote and point it to Flipper's IR receiver.
|
|
2. Start learning a new remote if it's the first button or press `+` to add a new button otherwise.
|
|
3. Press a remote button and save it under a corresponding name.
|
|
4. Repeat steps 2-3 until all required signals are saved.
|
|
|
|
The signal names are self-explanatory. Remember to make sure that every recorded signal does what it's supposed to.
|
|
|
|
If everything checks out, append these signals **to the end** of the [TV universal remote file](https://github.com/flipperdevices/flipperzero-firmware/blob/dev/applications/main/infrared/resources/infrared/assets/tv.ir).
|
|
|
|
## Audio players
|
|
|
|
Adding your audio player to the universal remote is done in the same manner as described above. Up to 8 signals can be recorded: `Power`, `Play`, `Pause`, `Vol_up`, `Vol_dn`, `Next`, `Prev`, and `Mute`. Any of them can be omitted if not supported by the player.
|
|
|
|
The signal names are self-explanatory.
|
|
On many remotes, the `Play` button doubles as `Pause`. In this case, record it as `Play` omitting the `Pause`.
|
|
Make sure that every signal does what it's supposed to.
|
|
|
|
If everything checks out, append these signals **to the end** of the [audio player universal remote file](https://github.com/flipperdevices/flipperzero-firmware/blob/dev/applications/main/infrared/resources/infrared/assets/audio.ir).

|
## Projectors
|
|
|
|
Adding your projector to the universal remote is really simple. Up to 4 signals can be recorded: `Power`, `Mute`, `Vol_up`, `Vol_dn`. Any of them can be omitted if not supported by your projector.
|
|
To save time, please make sure every recording has been named accordingly.
|
|
In case of omitting, on most projectors with the 4 following buttons, you should not have a problem.
|
|
|
|
|
|
## Air conditioners
|
|
|
|
Air conditioners differ from most other infrared-controlled devices because their state is tracked by the remote.
|
|
The majority of A/C remotes have a small display that shows the current mode, temperature, and other settings.
|
|
When the user presses a button, a whole set of parameters is transmitted to the device, which must be recorded and used as a whole.
|
|
|
|
In order to add a particular air conditioner to the universal remote, 6 signals must be recorded: `Off`, `Dh`, `Cool_hi`, `Cool_lo`, `Heat_hi`, and `Heat_lo`.
|
|
Each signal (except `Off`) is recorded using the following algorithm:
|
|
|
|
1. Get the remote and press the **Power Button** so that the display shows that A/C is ON.
|
|
2. Set the A/C to the corresponding mode (see table below), leaving other parameters such as fan speed or vane on **AUTO** (if applicable).
|
|
3. Press the **POWER** button to switch the A/C off.
|
|
4. Start learning a new remote on Flipper if it's the first button or press `+` to add a new button otherwise.
|
|
5. Point the remote to Flipper's IR receiver as directed and press **POWER** button once again.
|
|
6. Save the resulting signal under the specified name.
|
|
7. Repeat steps 2-6 for each signal from the table below.
|
|
|
|
| Signal | Mode | Temperature | Note |
|
|
| :-----: | :--------: | :---------: | ----------------------------------- |
|
|
| Dh | Dehumidify | N/A | |
|
|
| Cool_hi | Cooling | See note | Lowest temperature in cooling mode |
|
|
| Cool_lo | Cooling | 23°C | |
|
|
| Heat_hi | Heating | See note | Highest temperature in heating mode |
|
|
| Heat_lo | Heating | 23°C | |
|
|
|
|
Finally, record the `Off` signal:
|
|
|
|
1. Make sure the display shows that the A/C is ON.
|
|
2. Start learning a new signal on Flipper and point the remote towards the IR receiver.
|
|
3. Press the **POWER** button so that the remote shows the OFF state.
|
|
4. Save the resulting signal under the name `Off`.
|
|
|
|
The resulting remote file should now contain 6 signals. You can omit any of them, but you then won't be able to use their functionality.
|
|
Test the file against the actual device. Make sure that every signal does what it's supposed to.
|
|
|
|
If everything checks out, append these signals **to the end** of the [A/C universal remote file](https://github.com/flipperdevices/flipperzero-firmware/blob/dev/applications/main/infrared/resources/infrared/assets/ac.ir).
|
|
|
|
## Final steps
|
|
|
|
The order of signals is not important, but they should be preceded by the following comment: `# Model: <Your model name>` in order to keep the library organized.
