Best smart home dashboard for Android?

Hi.

I am a HomeSeer user. Come here to explore options for homaAssistant. I hear really good things about it and the ongoing development seems outstanding.

What would be the best smart home dashboard for Android to start with. I don’t mind paying and support the developer for a good thing. It does not have to be free of charge.

Features I would welcome are:

Some of those are OS-related. Would also love to know how you manage it.

  • option to app start when system boots
  • lock the user inside the app (would not like people to exit and access my tablet settings)
  • use of proximity/motion detect sensor to control the brightness.
  • schedule for brightness (night and day mode)
  • lux sensor (camera) use for brightness

other related things:

  • can the HASS server read the battery levels of devices?
  • can the HASS server manage the brightness of the tablet devices using rules?
    My current HomeSeer server uses a motion detection sensor (MQTT) and changes tablet brightness to 100%, after few minutes it drops back to 50%.

Thank you
