shanned,
Thank you for your questions.
1. The Smart Bridge is not compatible with the existing line of Maestro Wireless products.
2. Initial access from the app requires internet access. Local network access is coming soon. Pico remotes will continue to function when the internet is lost, or even when the bridge is unplugged.
3. Scheduled scenes require an internet connection to keep the time up to date. Scheduled scenes will continue to function if the smart bridge loses internet connection and does not lose power.
