IRForum

Hi everyone,

I’m working on a project to build a device using a Raspberry Pi to control air conditioners via IR. From my research, it seems that each AC manufacturer uses its own unique IR codes, and many tutorials recommend capturing these codes manually with an IR receiver and then replaying them using a transmitter.

However, I’m wondering if there’s a more efficient way to achieve this:

Is there an accessible database of IR codes for different AC brands and models that I can use directly?

Are there any open-source projects or resources I can take inspiration from to control a wide range of ACs without the need to manually record commands?

Thanks in advance!

Not aware of any available database for AC signals (free or paid).

Your best option is to buy a universal AC remote from aliexpress and capture the signals.

We alsways suggest users just capture the most common signals they use and store them for later replay.

It is also paoosible to reverse engineer each IR protocol (multiple from each vendor) so that you can build the signals on the fly. We have many customers using AnalysIR to achieve this.....but it is a lot of work.
