FLIR is a total game-changer in thermal imaging.
From electricians and contractors to hobbyists and adventurers, it simplifies tasks and provides unmatched insights.
Whether you’re spotting heat leaks, checking electrical panels, or just having fun with thermal imaging, FLIR has your back.
But let’s be real now.
If you’re an iPhone user, connecting your FLIR One to your iOS device can feel like a bit of a puzzle.
Why won’t it just work seamlessly?
You’re probably wondering what you’re missing or if you’re doing something wrong.
Luckily, there are workarounds and easy fixes to get your FLIR One running smoothly on your iPhone.
In this post, I’ll walk you through the exact steps to troubleshoot and connect your FLIR One.
So you can focus on what matters—using it to get the job done!

Make Sure It’s the Right Model for iPhone

Before diving into fixes, let’s confirm you’ve got the correct FLIR model for your iPhone.

If you head to Amazon or any retailer, you’ll find multiple FLIR One devices—but not all of them are made for iOS. Many FLIR models are specifically designed for Android, with USB-C connectors. It’s easy to get confused and accidentally pick the wrong version, especially if you didn’t double-check compatibility before buying.

What to Look For:

The iPhone-compatible FLIR models come with a Lightning connector.

Popular options for iPhone users include the FLIR ONE PRO LT and the FLIR ONE PRO for iOS. These models explicitly mention compatibility with iPhones in the product description.

What If You Got the Wrong Model?

If you have an Android-specific FLIR One, there’s no quick fix—it simply won’t work with your iPhone.
You’ll need to exchange or return it for the correct version.

Pro Tip: Double-check your model by looking at the box or manual. It should clearly state that it’s for iOS devices. And when shopping online, always look for “Lightning connector” or “For iPhone/iPad” in the product title or specs.

Getting the right model is step one to enjoying seamless thermal imaging on your iPhone!

Check the Lightning Connector

Your FLIR One connects to your iPhone using a Lightning connector.
This design supports a wide range of iPhone models, even newer ones like the iPhone 13.
But if your FLIR One isn’t working, the problem could lie with the connector itself.

Here’s what you should do:

Unplug and Inspect the Connector

Carefully disconnect the FLIR One from your iPhone.
Check the lightning connector for dirt, lint, or debris.
Even the tiniest particles can interfere with the connection.
Use a soft, dry cloth or a cotton swab to gently clean the connector.
If there’s stubborn debris, a can of compressed air can help.

Check Your Phone Case

If you’re using a thick case, especially something like an OtterBox, it could be blocking the connector.
The FLIR One’s extendable lightning connector doesn’t always reach through bulky cases.
Remove your phone case and try connecting again to see if it solves the problem.

Reconnect Carefully

Plug the FLIR One back into your iPhone, ensuring it’s securely seated.
Avoid wiggling or forcing the connector, as this can damage the pins or the port.

Pro Tip: If the connector still feels loose or isn’t sitting properly, inspect your phone’s lightning port too.
Dust buildup inside your iPhone’s port could also cause connection issues.
Use a clean, non-metallic tool like a toothpick to gently clear it out.

Check for Firmware Updates

If the hardware is in good shape, like the lightning connector, it’s time to focus on the software.
Firmware that hasn’t been updated can cause connection problems, too.
Think of firmware as the behind-the-scenes software that keeps your FLIR One running smoothly.

Here’s how to check and update it:

Open the FLIR One App

Launch the app on your iPhone and ensure your FLIR One is properly connected.
If the app doesn’t detect the camera, unplug and reconnect it.

Access the Settings

Tap the settings icon in the app, usually shaped like a gear.
Look for a section labeled Firmware Update or Device Info.

Search for Updates

The app will automatically check if your firmware is up-to-date.
If there’s a new version available, follow the prompts to download and install it.

Install and Wait

Keep your iPhone and FLIR One connected during the process.
Be patient! Interrupting the update could cause issues!
Firmware updates can often improve compatibility with new iOS versions.

Wrapping It Up

Getting your FLIR One to work with your iPhone doesn’t have to feel like a chore.
Start simple.
Verify it’s the right model, inspect and clean the connector, and update the app or firmware.
If you’re still stuck, FLIR support is just a message away.
Worst case? Grab a new lightning-compatible connector.  And you’ll be back to snapping those awesome thermal images!
