Failures in the Lutron app will prevent you from applying your favorite settings to your house’s lights, so you must investigate the causes.

Remember that Lutron devices also need a smart bridge, so if you don’t have one, it is not possible to pair any switches to the Lutron app.

However, if you have everything necessary and it still won’t work, here are some possible causes:

Internet Connection

Devices that depend on your router to function correctly are very sensitive to anything going wrong in the local network.

Lutron Server

Remote servers keep up the app, so if they are down or suffering any issue, the app might show malfunctions.

Outdated App

All devices and software need to be up to date. That includes the app you are using.

Outdated Smart Bridge

When the smart bridge’s firmware is outdated, it might not transmit signals correctly to your Lutron devices.

Issues On Your Phone

Your phone might be facing some sort of bug or trouble communicating with wireless devices.

Investigating the causes of the Lutron app failing to work requires you to consider everything mentioned above. 

Sometimes one of the causes will click with something that’s been happening.

Other times, it is better to check all the solutions below until one of them fixes the problem.

Solution #1: Fix The Internet Connection

The most simple thing you can do when you notice the Lutron Caseta app not working is reset the internet connection.

Here is how you can do it:

  1. Locate your main router’s power button
  2. Hold it until all lights go out
  3. Wait a minute
  4. Turn the router back on

The above aims at “releasing” the traffic on your router. However, if such a thing keeps happening, you must check with your ISP if they are having trouble delivering enough speed. 

Alert: If the issue is not with the ISP, but you notice that resetting the router always works, there is something wrong with your router.

Solution #2: Update The App

update the lutron app

Depending on your phone’s current settings, it might not allow some applications to download and install new updates automatically.

In that case, your Lutron app might be outdated, which is why it can’t communicate correctly.

Update On Android

If you are using an Android phone, do the following:

  1. Open the Play Store
  2. Tap the three lines icon
  3. Select “My apps & games.”
  4. You will see a list of all apps on your phone
  5. If there is an “update” option for the Lutron app, click it

Update On iOS

On the other hand, iOS users must do the following:

  1. Open the App Store
  2. Click on the “Updates” tab
  3. A list of all app updates will show up
  4. If Lutron is on the list, click on “update” next to it
Note: An app update is necessary because the app must communicate to the Lutron network, which will send a signal back to your router. When the app is outdated, that doesn't happen properly.

Solution #3: Update The Smart Bridge’s Firmware

Like the app being updated, the Lutron smart bridge must also have the latest firmware to work correctly.

If necessary, it is possible to check and update the latest firmware through the Lutron app.

Here is how:

  1. Open the Lutron app
  2. Go to the “Settings” menu
  3. Tap on the “Software/Firmware Update” option
  4. If an update is available, choose to download it (ensure that your phone is connected to the same Wi-Fi network as the Smart Bridge)
  5. Once the download is complete, install the update
  6. The Smart Bridge will automatically reboot and install the update (it may take several minutes)

If the installation is successful, a second reboot should occur, followed by the front LED blinking green.

After that, just go to the app’s settings again and ensure the update has been installed. If it’s installed, then the app should work again.

Note: Remember that the bridge, phone, remotes, and switches must all be connected to the same network. The bridge can also connect via ethernet.

Solution #4: Restart Your Phone
