IKEA HOME SMART APP & TRÅDFRI GATEWAY
Grey line
I bought a gateway and a light bulb, I cannot seem to find the light bulb with
the TRÅDFRI gateway?
You need to have a steering device with the system, and you need to add a light source to the gateway with the steering device. You will be guided step by step how to do this in the IKEA Home Smart App.
Grey line
I connected my light source to the TRÅDFRI Gateway by using my remote control. Do I need the remote control anymore or can I just use the IKEA Home Smart App?
You can steer your lights without the remote control if you disconnect the steering device from the Gateway after you have used it to pair your light sources. However, if you decide later on to add more light sources to your system, you will need a steering device again.
Grey line
I followed the instructions and have paired the steering device (remote control, wireless dimmer and motion sensor) to the TRÅDFRI Gateway but I don’t see the bulb in the app.
You need to pair the bulb with the steering device since it lost the connection when you factory reset it by added the steering device to the Gateway.
Grey line
I cannot connect my TRÅDFRI gateway from the QR code. Is there another way to connect?
Yes. You can also connect your gateway by registering the gateway ID code manually in the app. You’ll find this code on the backside of your gateway.
Grey line
I’m having trouble downloading the IKEA Home Smart App.
Check the latest compatibility information in the App Store or Google Play.
Grey line
I cannot add the light source into the TRÅDFRI gateway.
To be able to add a light source to your Gateway you need to have a steering device (remote control, wireless dimmer or motion sensor). Follow the instruction in the app, meaning first add your steering device to your gateway, and then pair your light sources with that device.
Grey line
Do I need to have a TRÅDFRI gateway to use TRÅDFRI light sources?
No, you can control any TRÅDFRI light source with a TRÅDFRI steering device (remote control, wireless dimmer or motion sensor). You need a TRÅDFRI gateway to control TRÅDFRI light sources with the IKEA Home Smart App.
Grey line

1. Check that the gateway’s power is on. If not, check that the power supply cable is correctly attached.

2. Verify that the gateway is connected to your home router via a cable and that the router has internet connectivity.

3. To continue, you need to download the IKEA Home Smart App from Apple App Store or Android Play Store and follow the step-by-step guide in the app to set-up your gateway.

4. Follow instructions in the app on how to set-up your gateway and how to connect the steering devices and light sources.

5. Find the QR code on the backside of your gateway and scan it with your mobile phone following the instruction in the app. If you have a problem scanning the code, you can type the gateway code manually. You’ll find the gateway code on the backside of your gateway. If you still have problem, check that all cables are connected and try again.

6. Secure that your mobile phone is connected to your Wi-Fi network; the same network the gateway is connected to.

7. If you have problems, set-up the gateway by following the steps in the app. You can reset your products by doing a factory reset and do the installation again.

I accidentally changed my light settings in the App. How do I get my settings back?
The best way to save your light settings is to save them as moods. Once you have done this, if somebody changes them you can go into the Moods screen, press on your saved mood and all the lights will go back to the way you prefer them. Keep in mind that all the data is saved in your Gateway and in your network, so no cloud back-up is available for you to get saved data from 2 months ago.

Updating and resetting
IKEA HOME SMART APP & TRÅDFRI GATEWAY
Grey line
What do I do if a device fails during an update?
Try again. Turn ON all the light sources and make sure that there is a battery in the battery-operated products. It’s possible to retry an update from the Update devices screen inside the IKEA Home Smart App at any time. If the Gateway loses contact to the router while updating, check to see if your Gateway is connected to your router and that the router is connected to the internet.
Grey line
If I do a factory reset of the Gateway, what happens to the system (connected light sources) and the IKEA Home Smart App?
The factory reset will clean up all data saved in the Gateway and make it re-form a new ZigBee network. It will also work on the latest Over the Air (OTA) image it updated to so far, and revert to the factory flashed firmware. From a user perspective, this can only be triggered by using the pinhole-button. The rest of the system is left intact, meaning you can continue to use the rest of the devices in the system.

How to get the bulbs back in sync
Light sources can become out of sync when you interact with the main power switches (wall or lamp switches) with part of your connected light bulbs. For example, when you turn one light bulb in a group OFF with the power main switch and change the rest of the light bulbs in the group to another state, the turned-off light bulb will be out of sync when turning it on again with the power main switch.

I have more than one bulb connected to my motion sensor and they’ve become unsynced. How can I sync them again?

Grey line
I added a white spectrum light bulb and I don’t understand how I can change the colour with the wireless dimmer.
You can’t change colour with a wireless dimmer. To be able to change colour, you need to pair your light bulb with a remote control.

I’m having trouble adding a light source to my TRÅDFRI system.
Grey line
I’ve installed my lights, but when I try to pair them a different light responds.
If you have a light source with more than one light bulb that sits close together, you need to pair them one by one. Install your first light bulb, pair it and then remove it. Then install the second light bulb, pair it and remove it, etc. Do this with all of the light bulbs, installing all when you’re ready.
You can also watch a film for instructions: Getting started: Add several bulbs
Grey line
What do I do if my TRÅDFRI light bulbs aren’t responding to the steering device?
You always need to have a steering device to be able to control your light bulb. If you purchased the light bulbs separately, you need to pair them to the steering device one-by-one. You can also watch a film for instructions: Getting started: Add bulbs, doors and panels
Grey line
Why are my light sources out of sync?
Light sources can become out of sync when you interact the main power switches (wall or lamp switches) with just part of your connected light bulbs, e.g. when you turn one light bulb in a group OFF with the power main switch and change the rest of the light bulbs in the group to another state, the turned-off light bulb will be out of sync when turning it on again with the power main switch.

Can I turn my light on and off also without using a smart device?
Yes, you can use the main power switch, steering device or the IKEA Home Smart App.
Grey line
I have installed a motion sensor, but the light does not turn on when I move?
1. Secure that the lamp connected to the motion sensor main power is on.

2. Secure that the batteries are inserted in correct direction, with the IKEA logo (plus sign) facing upwards.

3. If you bought a kit it’s already paired. If you add additional lights you need to pair them with the motion sensor: Add a light bulb to the TRÅDFRI motion sensor

4. Is the dial on “Night” or “Day“? If the dial is on “Night” and it’s light outside, then nothing will happen.

5. Have you installed the motion sensor so that the sensor is directed where the motion will be, in the range of 120 degrees / 5m (16,5’)?

6. If you still have a problem, do a factory reset of your products and try again.

General questions
STEERING DEVICES
Grey line
I can’t get two steering devices to control the same group of lights at the same time.
You can control an existing group of light bulbs by just one steering device.
Grey line
I don’t have the Gateway or IKEA Home Smart App. What will happen if I add a second steering device to a light source?
The first steering device will unpair, or become disconnected, from the light source.
Grey line
What should I do if my steering device (remote control, wireless dimmer or motion sensor) is not responding?
Check that your battery still has power and that it’s inserted in the steering device correctly, with the IKEA logo (plus sign) facing upwards.
The steering device must be paired to your light source. If you purchased a dimming kit white spectrum, dimming kit or motion sensor kit, your steering device and light bulb are already connected.
