Philips Hue bluetooth + Sonos One + Alexa ?

So in other words :

Philips hue Bluetooth bulbs + Sonos One

--> unable to work with Alexa voice commands

Philips hue Bluetooth bulbs + Sonos Move

--> able to work with Alexa voice commands

Or perhaps even better still…

Philips Hue Bulbs of any Type + Any Sonos Product + Harmony Hub

--> able to work with Alexa or Google voice commands

I am no expert on Hue lights, but on further thought I  don't see how it matters whether the Sonos speaker has Bluetooth.  I assume the Bluetooth has to be sent to the bulb, and no Sonos speaker will do that.

The speaker would simply be acting as the means of instructing Alexa, presumably as part of the home network not using Bluetooth. 

Whether that works without a Hue Bridge I'm afraid I have no idea. 

I guess you'll need the hue bridge for it to work.

Or the Harmony hub like user Ken_Griffiths mentioned, but I'm not familiar with that.

I'm going to look it up.

The Hue Bridge is good, as you can use a variety of Apps with sonos audio via a mobile or PC device like Hue Disco, or Hue Sync etc; and lots more appsbesides.

I use a Hue Bridge (with Google Assistant on Sonos) myself (and would advise you to buy one because it works very well), but using Alexa with Hue without a Bridge seems possible: https://www.the-ambient.com/how-to/set-up-philips-hue-without-bridge-1563
