When an Aqara sensor looks wrong, I first separate accuracy from freshness. A high value and a stale value are different failures; comparing only the numbers can hide that distinction.
For one noncritical sensor, I record four things at the same time:
- the Aqara Home value and its last-updated time;
- the Apple Home or Home Assistant value and whether its timestamp changes;
- another channel from the same device that is known to update;
- a control reading from a nearby device after both sit in the same position for 20–30 minutes.
If Aqara Home changes but the bridged value freezes, I investigate the mapping or bridge path. If every channel updates except one, I focus on that channel, its sensor, or the app display. If all channels freeze together, I check power and connectivity before calibration. A constant zero in one ecosystem and a high last reading in another may be stale or unsupported data, not agreement.
Before resetting anything, I capture the firmware, hub, integration path, placement, and screenshots with visible times. Then I change one variable at a time. Which Aqara devices expose useful per-channel timestamps in Aqara Home?
