Topology screen with a Border Routers section showing Apple BorderRouter tagged as the Thread Leader, followed by a Thread devices list with router and child role badges and best/worst RSSI values

Mesh graph showing routers, the Border Router rendered as a half-cyan half-purple square to indicate it is also the Thread Leader, child accessories as small dots, and RSSI-coloured edges. A legend below explains each node shape and colour.

AI Diagnose screen with a one-sentence summary and several findings — including a HIGH-severity finding for an isolated router — each citing the exact RSSI values and accessory names involved

On-demand mesh graph

The actual Thread mesh, not a guess. RSSI-coloured edges, single points of failure ringed by severity, the Thread Leader marked — even when it's your HomePod.

Re-parent risk detection

Finds routers whose loss would orphan accessories — and grades how dangerous each one really is.

AI-powered fixes bring your own key

Findings cite real RSSI values, accessory names, and HomeKit rooms — not generic advice. Pay your provider directly.
