It may need to be paired to the hub first. I don’t recall if I did that first or tried the bulbs right out of the box. I can post a basic “stub” device type, but it should be fine even paired as a “Thing” since I’m assuming it just needs the network key, etc. that would be provided on join.
Pairing to the hub needs to be done on a factory reset remote (hold On and Off until remote stops flashing ~30 sec) using the same method as a bulb: hold On while ST is in discovery mode.
You hold the “On” button while holding the remote near the bulb (4" or so). The bulb will identify by flashing and if that’s the bulb you want, just keep holding the button until the remote stops blinking. If it grabbed the wrong one, let go of the On button right away and try the process again. It’ll pair/bind to up to 30 devices.
