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`, `Ch_prev`. Any of them can be omitted if not supported by the 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. Don't forget 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](/assets/resources/infrared/assets/tv.ir).
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`, `Mute`. Any of them can be omitted if not supported by the player.
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 players universal remote file](/assets/resources/infrared/assets/audio.ir).
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 which shows 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`, `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), while 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 the steps 2-6 for each signal from the table below.
The order of signals is not important, but they must be preceded by a following comment: `# Model: <Your model name>` in order to keep the library organised.
