Based on your post above, I reached out to Wyze to get their feedback, and here is their response:
"Thanks for reaching out! To be transparent, we were considering both IFTTT and Stringify integration, but the fees demanded by Stringify were much higher than we could afford at the time, which is why we prioritized IFTTT. We are constantly prioritizing and re-prioritizing based on customer requests and our internal roadmap. Stringify is definitely up there, but we have to take into consideration the impact of Stringify vs other features (Google Home, outdoor camera, RTSP, etc). "
So it would seem that Stringify priced itself out of contention . . . Bummer . . .
