What ThinkQ device?
You may be able to integrate these with Echo Speaks.
Feit
Some (all?) Feit devices use Smartlife/Tuya's API. I have an integration for switches on that API if you're feeling technical. Aaiyar's link is good, too!
Roku
Edit: It's supported!
Wyze
There's somewhat of a support for this ... You can install their different firmware for RTSP support and add those to a dashboard for browsers supporting it. Not sure if others have done more.
