Implementation checklist

1
Confirm certification

Check the exact product model, firmware and certification database rather than assuming a logo guarantees compatibility.

2
Map the transport

Separate the application standard from the physical transport, hub, border router and cloud dependency.

3
Verify the ecosystem

Test the app, account region, sharing, automation and offline behaviour before deployment.
