Welcome Woody. I am not suggesting that you should not use the Hue bridge, but will add that I have 6 classic white hue bulbs included without a hue hub. They were marked for clearance at a local hardware store so I took a chance and they’re all working fine, surviving minus 45 degrees last winter in exterior fixtures.
as quoted from above link " Note: SmartThings’ Philips Hue integration requires use of the Philips Hue Ethernet Bridge. Connecting directly to Philips Hue lights is not currently supported. The Hue Bridge must be updated to firmware version 01016441 or later. To force your Hue Bridge to update its firmware: Close the Hue mobile app, unplug the Bridge for 10 seconds, plug it back in, and then restart the Hue app."
So it doesnt require a hue hub to get the lights working?
When you link your Hue bridge with SmartThings, You can then include your hue bulbs in your SmartThings rules.
That means, for example, If your smoke alarm goes off you could have your Hue lights come on, your front door unlock, and your outdoor sprinklers go on all at the same time.
Or when you turn on your television at night, you could automatically dim the hue lights in the room.
Or you could have one Hue light turn blue when the mail arrives or when the washing machine is finished.
Or have one hue light turn orange if the toddler’s door is opened between 10 PM and 6 AM.
Or have a different hue light turn orange if the front door is still unlocked at 10 pm.
You will still be able to do anything that you do with the hue bridge and Hue’s own app, But now you will also be able to combine your Hue bulbs in rules with your other SmartThings devices. As you can see there are a lot of possibilities.
(Although there are a few people who use Hue bulbs without the hue bridge, please read the FAQ about that. It can really mess up your zigbee network. )
If you have your Hue bulbs on a hue bridge And you don’t want to combine them with SmartThings, that’s fine. But once you do have them communicating with each other, you then have the option to do a lot more with your home automation system.
