Like I will using Bluetooth trackers so I want the main home page to show devices of the room I am in.
As I enter another room then the home page should one display only the devices from the new room.
Hope the above makes sense?
Aha, I see what you mean. Based on your wishes, I don’t think SMARTi. is the correct solution for you. Think of SMARTi as a global dashboard for your home that anyone can use no matter where they are located and what device they use.
Implementing a solution that will do what you describe will not be possible to implement on a general level (one solution that will fit all users) unfortunately.
SMARTi will however provide you with an overview of all your rooms with a quick access button to show all the devices in that room.
Would you consider a one off purchase instead of a subscription model? Regardless of how good it may be, subscriptions are a massive turn off
I have considered it yes but I am still debating how to best go about this. The main question how much a lifetime purchase should cost compared to a subscription model, but I am open to suggestions 
A “demo” version of the mode for smartphones would be useful. The dashboard looks interesting however I have no idea how it will look and perform on a phone. Probably most people, like me, mainly use a smartphone to operate HA and I would love to check the dashboard on it before I decide to subscribe.
I will consider it, but its not planned at the moment. I might upload a video showing how it works on a phone if that might help.
