The new devices tab in the mobile app is a great improvement - it makes a lot easier for people to get started, among other things, thank you.
A few suggestion, items of relatively low efforts and high value:
- Omit beginning of the device name if it matches the room name,
For example: I may have a "Kitchen Island Light" in the "Kitchen" room.
In this case the button label could just say: "Island Light". - Add an option to Select a default tab for the mobile app, choose between dashboards and devices.
- Add an option to hide the dashboards tab (A user may decide the devices tab is enough for his/her needs).
In the web app:
- Add a flag to the room to prevent it from showing in the mobile app.
- Mark a room as favorite so it always shows at the top in the mobile app or, a more elaborated solution: provide custom sort order.
I mention low effort and high value so I will stop here 
Thanks again and keep up the good work.
