When an Aqara child device is online in Aqara Home but missing from Apple Home or Home Assistant through a Matter bridge, I avoid resetting the device or bridge first. I compare three lists:
- child devices shown online under the Aqara hub;
- devices the hub says it currently exposes through its Matter bridge;
- accessories the target controller actually received.
For each item I record the model, a temporary unique name, room, and controller path. If a device is missing from list 2, repeated commissioning on Apple Home or Home Assistant cannot expose it; the question is bridge support or hub firmware. If it appears in list 2 but not list 3, I focus on the Matter commissioning and controller side. If it appears in all three but control is stale, I test one on/off command in each app and timestamp the results.
Before removing anything, I also note which automations and scenes reference the accessory. That preserves enough evidence to choose the failing layer without turning a visibility problem into a larger rebuild.
