The device name is polled during the discovery process only, not during a regular polling period. If you change the name of a device after it has been discovered in the Gateway, the new name will not appear in the device list automatically.
To manually update device atrributes in Gateway versions 1.8.1 and later:
- Log in to the Gateway.
- Go to the device and click the Details tab.
- Click Retrieve details.
In previous Gateway versions, rediscover the device to update its name.
In general, static values for device attributes are only polled at discovery, for example, the items on the device details page. Sensor measurements are polled during the regular polling period.
