Full manual for the Ocrustar Smart IR Blaster — how it works, download the app, connect the blaster, match appliances, the learning function and DIY code library, plus a complete FAQ and safety notes.

Note

This product is an infrared remote control device and only supports infrared-controlled appliances. After over a decade of collection and updates, it supports over 8,000+ brands of infrared appliances. However, due to the vast variety of appliances available, we cannot guarantee 100% compatibility. If you encounter an appliance model that cannot be controlled, we sincerely apologize. Please provide feedback to help us add it. We will try our best to find the corresponding code but cannot guarantee success. If you have the original remote control, you can either learn its signals using the learning function or email us at [email protected].

I. Product Overview

The working principle of this product is as follows: the Smart IR Blaster requires a compatible smartphone app (Ocrustar) to function. The app contains a vast database of infrared codes. Through a matching process, it finds the appropriate infrared code to enable the phone to control infrared appliances. The infrared code must be emitted by the IR blaster. Phones with built-in IR functionality can use the app directly without any additional hardware; phones without built-in IR must use a Smart IR Blaster.

II. Quick Start Guide

1. Download the App

iOS: Scan the QR code, or search "Ocrustar" on the App Store.

Android / HarmonyOS: Scan the QR code, or search "Ocrustar" on Google Play, the AppGallery, Huawei AppGallery, or other major Android app stores.

2. Insert the Smart IR Blaster & Connect to the App

  1. Open the Ocrustar app.
  2. Insert the Smart IR Blaster into the phone's USB port. A connection-success pop-up should appear on the phone.

Enable OTG first on some Android phones

For some Android models, you MUST enable the OTG function in your phone's settings beforehand; otherwise, the connection pop-up will not appear. This applies to brands like Vivo, OPPO, Xiaomi, OnePlus, Realme, etc.

3. Match the Target Appliance

  1. Tap the icon, or the "List" icon in the top-left corner.
  2. Open the "Appliance Type" page, select the appliance type and brand, then enter the matching page.
  3. Follow the on-screen instructions: tap the buttons and check whether the appliance responds correctly.
  4. Signal confirmation: when you tap a button and the Smart IR Blaster's green indicator light flashes, the signal was emitted successfully. If the appliance doesn't respond, try the next set of codes ("Try next").

Learning function (found at the bottom of the Appliance Type page): if you have the appliance's original and functional remote control, you can record its button signals directly into the app for use. Follow the in-app instructions.

DIY code library (found at the bottom of the Appliance Type page): this library mainly contains codes learned by users. If you cannot find a match using the standard library, try searching here to increase the matching probability.

4. Save Your Remote

After matching is complete, save the remote controller. Saved remotes appear in the Remote List, where you can delete, rename, and reorder them.
