I realize that particular topic is several years old, but I hope that keeping it active will encourage Wyze to consider many of the good suggestions there as they continue to develop their backend and future versions of the app. If you haven’t yet done so, you can visit that topic, click/tap the Vote button above the initial post, and add your own comments/thoughts in support of the features (and relevant use cases) you’d like to see.
