Moving a weak Zigbee sensor to a nearer Aqara hub may improve radio reliability, but it also changes the path that drives camera recording. Before re-pairing the real sensor, I would build a temporary automation with a spare sensor on the second hub and use it to trigger the same noncritical G410 recording action.
Record four things:
- whether the automation can select the G410 recording action across hubs;
- the time from sensor event to recording start;
- whether the clip appears with the correct timestamp;
- what happens after either hub is rebooted.
Only after that passes would I move the original sensor, and I would screenshot its existing automations first. This separates “the sensor stays online” from “the camera workflow still works,” which are two different success criteria.
