Can you still use your existing light switches with Hue?


A common question that pops up when it comes to the Philips Hue is can you use your main light switch, what happens when you do, and what can you do to over it.

How do you turn off a smart LED bulb?

To turn your lights on and off you can use your phone and the relevant app, if the bulbs work with Apple HomeKit or Alexa, then you can use voice commands to change there state.

The key not smart bulbs and the one thing they all have in common is that they all need constant power to them, so they must always be switched on at the mains be it at a plug socket or the main wall light switch.

Using Hue with your Existing Switches

In your home you will already have light switches that work the main light in the room turning it on and off, however when using Hue, the light switch becomes redundant and not needed, however it does need to be left turned on so power it always going to the Hue bulb.


Lights switches in the room should always be left on if you have a Hue bulb in there, you can then turn the bulb on and off using your phone, or Alexa for example.

If you were to turn the switch off, then the Hue bulb in that room will lose power and won’t respond to any actions to turn it on, turning the light switch back on will activate the bulb to its default state which is a bright warm white glow. This state is the default on state and will also occur if there is a power cut and when the power comes back on.


If your room has a dimmer switch then it is advised not to use this with the Hue bulbs, the dimmer will have to be left on max, however this can cause the bulbs to flicker, and humming noise and also reduce the lifespan of the bulbs. If you have a dimmer in your room then it is advised to replace this with a standard switch. You can then use a Hue Dimmer to work as a dimmer switch in that room if you wish.

      Can I just remove the existing light switch and wire the wires inside together so the lights are always on – then put the Hue Dimmer switch over the opening?
