I had been using the Alexa Helper to control ST for a long time, but decided to try the new Hue skill. That skill stunk. So I deleted it and went back to ST - reinstalling the Smartthings Skill, and then verifying the Alexa Helper smartapp is working and has everything exposed. All looks good but Alexa can’t find any ST devices.
I’ve rebooted everything in various orders, and tried reinstalling in various orders, with no luck.
The only thing I can think - when I was uninstalling the Hue skill, it was stuck and I had to go into the Hue Clip interface to delete the whitelist item for that skill. I also deleted a few Echo items I saw, to start everything fresh.
Hue works great with Alexa still, but ST doesn’t. Can’t figure it out!
