A keep alive allows monitoring a device communication status period. This is useful for watching the device health status.
The keep alive is defined Device Type level. The communication status indicator will change according to the keep alive setting compliance.
You can also set up a Service > Error Callback in the Callback section in order to be notified when a device fails to comply with its keep alive delay. See callback documentation.
Please be advised that this callback will be triggered after the keep alive delay is spent, e.g. the callback will be triggered 24h after the last message if the keep alive is set to 24h.
- Acces a device type by clicking its name from the Device type tab.
- Click the Edit button in the top right corner
- Enter a value in minutes in the Keep alive field
- Save the changes by clicking the Ok button
