Home Assistant IR Remote Setup Guide: Control TV, AC and Appliances with IR Blasters

An IR blaster can give Home Assistant a way to send commands to compatible televisions, air conditioners, audio equipment, and other infrared appliances that were never designed for a smart home. The setup is straightforward when you separate three decisions: what the appliance uses, how the IR device connects to Home Assistant, and where the transmitter is placed.

This guide explains the practical setup path for a Home Assistant IR remote, from identifying an appliance to building a first automation. It focuses on configuration and everyday use rather than product rankings. For a broader comparison of devices, see our Best IR Blasters for Home Assistant guide.

What Is an IR Blaster and How Does It Work?

An IR blaster is a transmitter that sends infrared commands in the same general way as a handheld remote. Home Assistant provides the automation logic, while the IR device sends the command toward the appliance. A power command, input change, volume adjustment, or temperature setting is therefore a signal path: Home Assistant action, compatible integration, IR transmitter, and appliance receiver.

Infrared normally needs a clear path to the receiver. The sensor window is often on the front of a TV, set-top box, amplifier, or air conditioner. A transmitter can work from a nearby shelf or cabinet, but furniture, closed doors, and an awkward angle can reduce reliability. Placement is part of setup, not an afterthought.

IR control also behaves differently from a device with two-way status reporting. Some appliances accept a command without sending their current state back to Home Assistant. Start with one command, confirm the physical result, and only then build a larger scene.

What Devices Can Home Assistant Control with an IR Blaster?

An IR blaster is intended for appliances that receive infrared remote commands. Depending on the appliance, available codes, and the integration you use, common categories include:

  • Televisions and set-top boxes
  • Air conditioners and heaters
  • IR-controlled fans
  • DVD players and other media players
  • Audio equipment, amplifiers, and receivers
  • Humidifiers
  • Some cameras and projectors that use IR remote commands

Compatibility is device-specific. A product category can use several remote-code families, and an appliance may expose only some of its physical remote functions through a given integration. Before building an automation, identify the appliance model and confirm that the required commands are available.

For LinknLink users, eRemote HA is the relevant IR-focused product path. Its product workflow is intended for bringing compatible infrared appliances into a Home Assistant setup. The exact commands available still depend on the appliance and the configured integration.

IR vs RF: Understanding the Difference

IR and RF are different control methods. Infrared uses light outside the visible spectrum and normally needs the transmitter to face the appliance receiver. Radio frequency uses radio signals and can often work without the same line-of-sight relationship. Choosing the wrong type of hub is a common reason a setup does not behave as expected.

IR devices

Use an IR path for compatible TVs, set-top boxes, air conditioners, heaters, IR fans, DVD players, audio equipment, humidifiers, amplifiers, and some cameras or projectors. An IR remote can replace repeated handheld commands, but it does not turn an RF appliance into an IR appliance.

RF devices

RF examples include RF plugs, electric curtains, roller blinds, RF bulbs, grow lights, RF switches, ceiling fans, electric fireplaces, and RF sockets. These need an RF-capable control path, such as eHome HA, when the device protocol and integration are supported.

For a system that contains both types, keep the paths explicit in Home Assistant. Use the IR entity or service for the TV and AC, and the RF entity or service for a curtain or ceiling fan. Our Home Assistant remote control guide covers the wider IR, RF, and MQTT architecture.

Before You Connect: Make an Appliance Command Map

Before opening Home Assistant, write down the appliance, its room, the receiver location, and the commands you actually need. A TV may need power, input, and volume. An air conditioner may need mode, temperature, and fan speed. This small command map keeps the first setup focused and makes it easier to tell whether a missing action is a code limitation or simply not configured yet.

Also record which devices are IR and which are RF. A TV and an IR-controlled AC can share the IR setup path, while a radio-controlled curtain or ceiling fan needs a separate RF-capable path. Keeping this boundary clear prevents an automation from calling the wrong entity later.

Home Assistant IR Remote Setup Workflow

The names of menu items vary by integration and current Home Assistant release, but the setup logic is consistent. Work through the physical connection first, then verify one command before adding automation.

1. Connect the IR device and choose its position

Connect the IR device according to its product instructions and place it where its transmitter can face the target receiver. For a TV or amplifier, a shelf near the front of the cabinet is often easier to test than a hidden position. For an air conditioner, check the location of the indoor unit’s IR receiver and avoid placing the transmitter behind an obstruction.

If more than one appliance is in the room, confirm that the transmitter’s position covers the receivers you intend to use. A multi-room system may need an IR device in each room rather than one unit placed at a distance.

2. Add the supported Home Assistant integration

In Home Assistant, add the integration or connection method supported by your IR device. Follow the device documentation for network, account, or MQTT details where applicable. Use the same Home Assistant instance that will run the automation, and give the device a clear name such as living_room_ir.

Do not assume that every IR blaster uses the same integration or that every product supports the same connection method. The device page and current integration documentation are the source of truth for the setup available to you.

3. Configure remote codes and entities

Select the appliance model or learn the required remote commands, depending on the available workflow. Start with a small set: power, volume, input, or a simple temperature command. Use descriptive names that make the command’s purpose clear, for example living_room_tv_power or bedroom_ac_cool.

Air conditioners deserve extra care because one IR message can contain mode, temperature, and fan-state information together. Test the actual state you want rather than assuming that a single power toggle has the same meaning in every state.

4. Create a small automation

Build the first automation around one trigger and one IR action. For example, a Home Assistant dashboard button can send a TV input command, or a schedule can send an AC setting at a defined time. Keep the first version easy to inspect so you can tell whether the trigger, action, and physical result agree.

When you combine an IR action with other devices, make the sequence intentional. A movie scene might turn on the TV, select an input, and adjust audio. If the scene also uses lighting or presence sensors, confirm each action independently before joining them.

5. Test the command from the final installation position

Run the command from Home Assistant while the IR device is in its intended position. Test from the normal angle and distance, with cabinet doors in their usual state. Repeat the command a few times and confirm the appliance’s physical response. This check catches placement and code problems before they become confusing automation behavior.

Turning Verified IR Commands into Home Assistant Automations

TV control from a dashboard

Create a dashboard button for power, input, or volume. This is a useful first project because the result is easy to see and the command is usually simple to verify. Add more buttons only after the first one works from the final transmitter position.

Scheduled air conditioner settings

A schedule can send an AC command before bedtime or before a room is normally used. Choose a complete, intentional setting where the appliance and integration support it, and allow time for the unit to respond. Avoid treating the IR command as proof of the room’s current temperature or HVAC state unless another sensor provides that information.

Movie mode

A movie scene can combine an IR TV input command with Home Assistant actions for other connected devices. Keep the IR portion limited to appliances that actually use infrared. For example, the TV and amplifier can use the IR path while a compatible light or curtain uses its own Home Assistant integration.

Sleep scene

A sleep scene can send a TV power command and an AC setting at a chosen time. Add conditions and a delay only when they reflect the way your household uses the room. If you want to trigger a scene from occupancy or temperature, use a separately connected sensor; an IR blaster itself does not provide presence or climate sensing.

Planning an IR-Controlled Room

The right choice depends on the setup you are trying to build, not on a universal ranking.

  • Simple IR control: choose an IR path that covers the appliance you want to command and supports the Home Assistant connection you plan to use.
  • Multi-room automation: plan transmitter placement room by room. A clear line of sight and a useful entity name can matter more than adding complexity to one central device.
  • Advanced Home Assistant setups: use the integration and connection method documented for your device, then model each appliance action explicitly so automations remain readable.

eRemote TV Kit may be relevant for a TV-focused setup when its supported product workflow matches your requirements. It should be evaluated as a specific product configuration, not assumed to cover every IR appliance or every Home Assistant integration.

When an IR Setup Needs Another Check

The appliance does not respond

First run the command manually from Home Assistant. If it works manually but not in an automation, inspect the trigger and action separately. If it does not work manually, check the selected code, the integration connection, and the transmitter’s direction.

The range or angle is inconsistent

Move the transmitter closer to the appliance receiver and remove anything blocking the path. Test with cabinet doors open, then in the final arrangement. If the result changes, placement rather than the automation logic is the likely variable.

A remote code works for one action but not another

Confirm that the code belongs to the exact appliance model or learn the missing command when that workflow is available. Test power, input, and volume independently on a TV; test mode, temperature, and fan settings independently on an AC.

The AC state seems out of sync

Many air conditioners receive stateful IR messages. Check the appliance’s current state, send a complete supported command, and avoid relying on a toggle when an explicit mode or temperature action is available. A separate temperature sensor can provide room context, but it does not confirm that the AC received a particular IR message.

FAQ

Can Home Assistant control a TV with IR?

Yes, Home Assistant can control a compatible TV through an IR blaster when the required integration and remote commands are available. Place the transmitter so it can reach the TV’s IR receiver, then verify one command manually before creating a scene.

Can Home Assistant control an air conditioner with an IR blaster?

It can control a compatible air conditioner through supported IR commands. AC remotes often send several settings together, so test the exact mode, temperature, and fan command you plan to automate.

What is the difference between IR and RF?

IR uses infrared signals and generally needs a path to the appliance receiver. RF uses radio signals and is used by a different class of devices, such as some plugs, curtains, blinds, switches, and ceiling fans. An IR blaster should not be used as an RF controller.

Does Home Assistant work with universal IR remotes?

It can, when the universal remote or IR hub exposes a supported integration and the required appliance codes. “Universal” does not mean every appliance or every command is automatically available, so confirm the device workflow and test the commands you need.

Conclusion

A reliable Home Assistant IR remote setup starts with the correct signal type, a compatible integration, clear transmitter placement, and small tests. Once a manual command works from the final position, it is easier to build TV scenes, AC schedules, and multi-device routines that remain understandable.
