Why Does My Phillips Hue Dimmer Switch Blink Red

If you ever run into your Phillips Hue switch blinking red, you may wonder, “why does my Philips hue dimmer switch blink red?” We reveal the 7 main reasons why it happens!

Philips hue dimmer blinking red can indicate a variety of issues. The issues may include a power issue, a communication issue, or a hardware issue. A power problem may be caused by a bad connection, a loose wire, or a problem with the power source. A communication issue may be as a result of a bad connection, interference, or a problem with the Hue Bridge. A hardware issue can be caused by a defective dimmer switch, a faulty bulb, or another problem with the hardware.

7 Main Reasons Your Philips Hue Dimmer Switch blinks Red?

1. Low battery

Philips hues will blink red when the batteries are low. You can

still use the switch, but you’ll need to replace the batteries soon. To do so,

unscrew the back plate and remove the old batteries. Insert new AAA batteries

and screw the back plate back on. Also, check the diagram on the back of the switch and ensure that the batteries are inserted correctly. Note that

you’ll need to re-pair your switch with the bridge if you’ve replaced the


2. Software updates

Philips hues undergo regular software updates to improve

performance and security. If your dimmer switch starts blinking red, it

indicates an update available. To install the update,

follow the instructions in the Philips Hue app. Once the update is installed,

your dimmer switch will return to normal operation.

Also, the hue may blink because someone made changes to the

system systems. Ask people in your family or home if they did before taking action.

The dimmer is not configured correctly.

Sometimes, technology can be frustrating. Even when you follow

the instructions to a tee, something can still go wrong. If your Philips Hue

dimmer switch blinks red, it is not configured correctly.

There are a few things that you can do to try and fix this

problem. First, ensure that the Hue bridge is properly connected to your

router and has an internet connection. Next, check to see if the Hue

app is up-to-date. Finally, try resetting the dimmer switch.

If you have tried all of these things and the dimmer switch is

still blinking red, then you may need to contact Philips customer support for

further assistance.


2. Faulty Zigbee connection

The Zigbee is the communication protocol that Philips Hue

uses. If the dimmer switch blinks red, it means a problem

with the Zigbee connection.


There are a few things you can try to fix this:

1. Restart your Philips Hue bridge.

2. Check if there is a firmware update available for your

Philips Hue bridge.

3. Try resetting your Philips Hue dimmer switch.

4. Using a Z-Wave or ZigBee repeater, try moving it

closer to the Philips Hue bridge.

5. Make sure that there are no obstructions between the Philips

Hue dimmer switch and the Philips Hue bridge.

6. Check if there are any other devices in your home that could

be causing interference with the Zigbee signal.

3. Lightbulb issue

Your Philips hue dimmer may blink red because of lightbulb

issues. One of the three main issues could be the case: too many

lightbulbs are connected, the firmware needs to be updated, or the lightbulb is

burnt out.

If you have too many lightbulbs connected, disconnect

some of them and see if that solves the problem. If your firmware needs to be

updated, connect your bridge to your computer and follow the instructions.

Lastly, if one of your lightbulbs is burnt out, replace it with a new


You can also troubleshoot your dimmer switch by resetting

it. To do so, press and hold the on/off button for about 10 seconds until the

light on the front of the dimmer switch blinks green.

4. Restart the Bridge

Just like your PC or phone, sometimes your Philips Hue

bridge needs a restart to fix technical issues. Unplug the bridge, wait for 2 minutes and plug it back.

After the bridge finishes starting up, check to see if the issue

is resolved. If not, try resetting the bridge.

5. Soft reset

A soft reset will clear any settings that may have been changed

and allow you to start fresh with the configuration process. All you have to do

is press all four buttons on the dimmer for about five seconds. The

light on the device will then go green, indicating that it has been reset


6. Hard reset

A hard reset should be the last option because it sets your

Philips Hue system is back to factory defaults. All your custom

settings will be deleted, like light names and rooms. Note that you will have

to reconfigure your system from scratch after a hard reset.

The hub has a hole in the back. Stick a paperclip in the hole

and press and hold for about 15 seconds. This will delete everything and reset

the hub to its factory settings.

Once the hub is reset, you can start from scratch by following

the instructions in the Philips Hue app.

You will need to uninstall and reinstall the official

app and any third-party apps you use with your Philips Hue system.

A hard reset will delete all your custom settings, like light

names and rooms.

7. The dimmer is faulty and need to be returned to the store

Sometimes, you may exploit all the avenues, but the dimmer

doesn’t work. At this point, you can return the dimmer to the store and get a

likely be willing to refund your purchase or offer a replacement. However, if
