# Universal Remotes
|
|
## Air Conditioners
|
|
### Recording signals
|
|
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.
|
|
|
|
| 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 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. Any of them can be omitted, but that will mean that this functionality will not be used.
|
|
Test the file against the actual device. Every signal must do what it's supposed to.
|
|
|
|
If everything checks out, append these signals **to the end** of the [A/C universal remote file](/assets/resources/infrared/assets/ac.ir).
|
|
|
|
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.

When done, open a pull request containing the changed file.
