IRTuya

IRTuya is an open-source IR code converter that supports multiple infrared remote control formats, including Tuya, Broadlink (Base64 and Hex), Raw, NEC, and LIRC. The application is available on Streamlit and its source code is hosted on GitHub.

Description

IRTuya is designed to facilitate the conversion and analysis of infrared signals used in various remote control systems. It provides functionalities to decode, convert, and analyze a range of IR code formats:

• Tuya IR Codes: Decode Tuya-specific compressed IR code strings into raw IR signal durations.
• Broadlink Codes: Convert between Broadlink Hex and Base64 formats and raw IR signals.
• NEC/NECx Codes: Decode and encode standard NEC and NEC Extended (NECx) commands.
• Raw IR Sequences: Directly manipulate and visualize raw IR data.

The program leverages efficient algorithms for decoding and compression (using FastLZ) and offers a user-friendly interface built with Streamlit. This makes it, I hope, a valuable tool for hobbyists and developers working with IR-controlled devices.

Usage

IRTuya provides a straightforward interface with an omnibox for converting and analyzing IR codes:

1. IR Transcoder

   • Input: Paste your IR code in one of the supported formats (Tuya, Broadlink, NEC, or Raw) into the provided text area.
   • Conversion: Click the "Convert" button to decode and visualize the IR signal.
   • Output: The application displays:
     • The decoded IR sequence in Raw format.
     • conversions, such as the Tuya code, Broadlink Hex, and Broadlink Base64 formats.
     • A graphic representation of the IR signal.

2. NEC / LIRC Sequences & Commands Encoder

   • Input: Enter a full NEC sequence or a short (address-command) code.
   • Options: Optionally select the NEC Extended (NECx) format and specify the number of repeats.
   • Encoding: Click the "Encode NEC" button to generate the corresponding raw IR signal.
   • Output: The application displays the converted codes and a visualization of the IR signal.

The interface includes helpful warnings and error messages to guide you in case of invalid input, ensuring a smooth and intuitive conversion process.
