You might be surprised to learn that IKEA has a well-developed line of smart home technology with its own ecosystem. I decided to explore these products, specifically the Tradfri Remote and smart bulbs. As with any smart home technology, you may experience some technical issues with the system’s communications. At first, I was unable to pair my Remote with the bulbs, and I wanted to find out why.

Why is the Tradfri Remote not Pairing to the Bulb? The most common cause of this issue is usually a communication error between the Tradfri Gateway and the Remote. It might even be a simple matter of updating your smart system’s firmware. Regardless, if you’re experiencing this or similar problems, it could be indicative of several easy-to-fix issues. 

If you happen to run into some of these issues like I did, there are some simple steps you can take to address the errors. This article will act as a guide to getting your IKEA Tradfri system set up and working the way you want.

IKEA offers many other smart home lighting products, available here, but the Remote, Bulb, and Gateway are essential to getting your system up and running.

Do I Need the Tradfri Remote to Use the Smart Bulbs?

You might be wondering, do I need the Tradfri Remote to use the associated bulbs? The short answer is yes; the Remote acts as an “activation” key required for the initial set up steps. The pairing process cannot be achieved via the associated mobile app.

According to IKEA:

You need one of the steering devices in the TRÅDFRI series (remote control, wireless dimmer or wireless motion sensor) in order to connect your light sources with the gateway and the app.

It’s worth noting that the bulbs can be used and configured using the app after the initial pairing. However, you will need the Remote for any new pairings.

How to Pair Tradfri Remote with Smart Bulbs

Now that we’ve examined the products required to get your IKEA Tradfri system setup, I’ve included a quick guide to pairing your new Remote with the Gateway:

  1. Remove the battery cover on the Remote.
  2. Screw-in your Tradfri light bulb to your light fixture.
  3. Locate the pairing button under the battery cover.
  4. Press and hold the pairing button for 10 seconds, within an inch of the bulb you want to pair.

*Note: You can repeat this pairing process with up to 10 Tradfri LED bulbs/Light Panels/light doors simultaneously. 

After following these initial setup steps, you should be good to go. I also found a helpful video tutorial that serves as a visual guide for the pairing process. With a better understanding of what the initial setup entails, let’s break down some of the potential issues you may encounter.

Potential Communication Issues and Solutions

So now your Tradfri smart light system is all set up, with your Remote configured and ready to pair. But what if you experience issues pairing the devices in your system? Here are some of the causes preventing you from pairing your Remote to your bulbs:

After following the appropriate pairing steps, bulbs won’t respond to the Remote.

  • Try restarting your entire system
  • Many users experience issues trying to pair the Remote to the bulbs before pairing to the Gateway. Make sure to pair the Remote with the Gateway before pairing with the bulbs.
  • Update your system’s firmware. Here’s a great guide that will walk you through the update process. 

A paired bulb no longer shows up in the IKEA app.

  • If your bulb is disconnected from the Tradfri Gateway, you may need to repair it using the Remote. You can’t pair the bulbs using the associated app.
  • You might be trying to pair the Remote too far away from the bulb. Verify that the Remote is within an inch of the bulb during the entire pairing process.

I have several bulbs paired to my Gateway, how can I turn them on/off simultaneously?

  • One potential solution to this issue is to create “Groups” that control all bulbs within the Group simultaneously.
  • Another workaround is to activate all the bulbs at once by pressing the “dim-up” button on the Remote to re-sync them at the same time.


If you’re experiencing issues pairing your Tradfri Remote to the smart bulbs, don’t worry, you’re not out of luck. There are many steps and visual guides available to get your system back on its feet. Hopefully, this guide was able to make the troubleshooting process more approachable and manageable for your needs.
