I am testing how the Tapo ecosystem works locally, with internet access for the hub blocked on the router. After disabling the internet, the current state of T110 is not available in the Tapo app - it still shows the last status when the internet was on. After re-enabling the internet, all missed status changes are displayed in the history, so the hub had them locally the whole time, but the app cannot access them from the local network.

One more thing I noticed: I linked H200 to the Apple Home app via Matter and after disabling the internet, Apple Home app still shows the current status of T110 while Tapo app does not.
