IR Remote Manufacturer — IR Blaster and Learning Remote OEM/ODM

An infrared remote controller is how you sell smart home to someone who is not going to replace their air conditioner. The TV, the set-top box, the split-unit AC and the projector are all still infrared devices. A hub that learns or already knows their codes turns them into app-controlled devices without touching the appliance — which is the only retrofit story that works in markets where replacing white goods is not on the table.

XingLiao builds IR blasters, IR + RF combination controllers and protocol bridges in Shenzhen, with sampling on existing platforms in 7 to 15 days.

What the product actually has to do

Air conditioner control is the hard part

Turning a television on with infrared is trivial: one code, one action. An air conditioner is different. The remote transmits the entire state — on, mode, setpoint, fan speed, swing — with every press, and the unit has no feedback channel. So the controller has to maintain state internally and resend the full frame every time.

The practical consequence: if the app and the physical remote are both used, they drift out of sync, and the customer concludes the smart controller is broken. Good implementations reduce this by keeping the app as the primary interface and by making the state visible in the app. We test AC control against real units rather than against a code list, because a code that transmits is not the same as a code that produces the right behaviour.

Line of sight is not negotiable

Infrared is light. It reflects off some surfaces, it does not pass through walls, cabinets or the back of a sofa, and its range drops sharply off-axis. A hub placed in a media cabinet with a closed door will control nothing. We specify 360° emitter arrays with multiple diodes and we state placement requirements in the quick-start card, because this is the most common cause of a return and the cheapest to prevent.

Where line of sight genuinely cannot be achieved, the answer is not a stronger emitter — it is a wired IR extender or a different product category entirely, such as a relay behind the socket. We will tell you when that is the case rather than sell you the wrong unit.

Where IR controllers get deployed

• Consumer retrofit: one hub per living room, controlling TV, set-top box and air conditioner from the phone.
• Apartment rentals: landlords cannot replace appliances, so an IR controller is the only automation option.
• Hotels: centralised control of in-room air conditioning, with a defined scene at check-in and an eco scene at check-out.
• Mixed RF and IR sites: a combination unit that also drives 433 MHz curtain motors and screens.
• Accessibility use: voice control of existing appliances for users with limited mobility.

The code library is a long-term commitment

This is the part buyers underestimate. A remote that works with today's televisions needs updating as manufacturers release new models. A supplier who ships a static code list is handing you a product with a decaying feature set and no plan to maintain it.

We maintain the library through firmware updates pushed over the air, and for private-label clients we support a branch where codes can be added on request. If your market has a specific dominant appliance brand, tell us at enquiry and we will validate those models specifically.

Private label scope

Standard controllers with your branding start at 500 pieces per colour. Firmware work — app branding, custom scene behaviour, installer provisioning — begins around 3,000 to 5,000 pieces, and new enclosure tooling takes 25 to 40 days.

These units are usually developed alongside a protocol bridge, automation systems and motion sensors for scene logic.

Certification

IR products still carry radio certification because of their Wi-Fi or Zigbee module: CE and RoHS for Europe, UKCA for Great Britain, FCC for the United States, PSE for Japan. RF-enabled variants add 433 MHz spectrum considerations that vary by country — 433 MHz is licence-exempt in some markets and not in others, so confirm the destination before quoting.

Frequently Asked Questions

Will it work with my air conditioner?

Probably, and AC is the hardest category because the remote carries full state. Send us the brand and model and we will check against the library before you commit.

Does it need line of sight?

Yes. Infrared is light — it will not pass through walls, cabinet doors or furniture. A 360° emitter array in a central position is the standard solution.

Can it also control RF devices?

On selected models, yes — 433 MHz fixed and rolling code support covers curtains, screens and RF sockets.

What happens if a code is missing?

The unit learns from the original remote. For private-label clients we can add codes to your firmware branch.

Can I still use the original remote?

Yes, but for air conditioners the app state may drift out of sync. Using the app as the primary interface avoids this.

What is the minimum order quantity?

500 pieces per colour on an existing platform; custom firmware or tooling from about 3,000 to 5,000 pieces.

Does it work offline?

Local scenes run on the device, so scheduled IR actions continue without internet. Remote control from outside the home needs a connection.

Is one unit enough for a room?

Usually yes, if it has a clear view of every appliance in that room. Rooms separated by a wall each need their own unit.
