Yeah I had the same issues. Here’s what you want to do
A: first thing you need to do is reset the hue bulbs with the lutron remote. That puts them in a state that will work with ST.
B: you need to have the kudlow device type installed in the IDE.
Then one at a time add turn those bulbs on. I did it by unscrewing them and putting them back in one at a time as I installed them.
Once the bulb is added you will have to go into the IDE on your computer, pull up the device and change it to the kudlow device, it will be at the very bottom of the list. Also change the name of it IE living room lamp etc. And name the service IE hue bulb. Once you hit save the device will now work on ST.
Now for the lutron remote you need to add to ST first. Do this by putting ST into scan mode in the add new device section. While it’s scanning hold the power button on the lutron remote. You should see it show up in ST as a thing. That’s all I did from ST to pair the remote. Now you take the remote and put it beside each bulb and hold the power button until the bulb connects and syncs. Keep in mind when I first did it the remote worked but ST didn’t control the bulb any more. I then took a break from it but when I got back up from a nap both the remote and ST are controlling the bulb. Good luck and let me know if you need any help.
