JD,
Official Integration. I deleted my integration, opened the new phone app. It discovered my TP-Link devices (all). Control worked; however, the state did not update as-expected. It seemed to be similar to same problem we had at one time with the classic app. State would update when you went to the details page or back to the devices page.
My Integration. I could not install the app in the new phone app. After installing using the classic phone app, it can be run in the new app to add devices. One good thing - with the energy monitor plugs (HS-300, HS-110, I was able to get the power and energy to display in the new app (it does not in the "official Integration). This required a change in the vid parameter.
