sync-at-time modular resource

This module allows you to configure Cloud Sync to occur only at a specific time frame by implementing a sensor, naomi:sync-at-time:timesyncsensor, that enables sync when within a specified timeframe and disables sync when outside that timeframe.

Requirements

Before configuring your sensor, you must create a machine.

To use the sync-at-time module you also need to:

1. Enable data capture.
2. Enable cloud sync.

Build and run

To use this module, follow these instructions to add a module from the Viam Registry and select the naomi:sync-at-time:timesyncsensor model from the sync-at-time module.

Configure your sync-at-time sensor

Navigate to the Config tab of your machine's page in the Viam app. Click on the Components subtab and click Create component. Select the sensor type, then select the sync-at-time:timesyncsensor model. Click Add module, then enter a name for your sensor and click Create.

On the new component panel, copy and paste the following attribute template into your sensor’s Attributes box:

{
  "start": "HH:MM:SS",
  "end": "HH:MM:SS",
  "zone": "<TIMEZONE>"
}

Note

For more information, see Configure a Machine.

Attributes

The following attributes are available for the naomi:sync-at-time:timesyncsensor sensor:

Name	Type	Inclusion	Description
start	string	Required	The start time for the time frame during which you want to sync, example: "14:10:00".
end	string	Required	The start time for the time frame during which you want to sync, example: "15:35:00".
zone	string	Required	The time zone for the start and end time, for example: "CET".

Example configuration

{
  "start": "14:10:00",
  "end": "15:35:00",
  "zone": "CET"
}

To ensure the sensor starts before the data manager, add the sensor to the dependencies of the data manager.

Configure data manager

On your machine's Config tab, switch to JSON mode and add a selective_syncer_name with the name for the sensor you configured to the data manager config. Also add the sensor to the depends_on field:

{
  "attributes": {
    "additional_sync_paths": [],
    "capture_dir": "",
    "capture_disabled": false,
    "selective_syncer_name": "<SENSOR-NAME>",
    "sync_disabled": false,
    "sync_interval_mins": 0.1,
    "tags": []
  },
  "name": "Data-Management-Service",
  "type": "data_manager"
}

For an example configuration see example.json.

Next steps

You have now configured sync to happen during a specific time slot. To test your setup, configure a webcam or another component and enable data capture on one of the component methods, for example ReadImage. The data manager will now capture data. Go to the Control tab. You should see the sensor. Click on GetReadings. If you are in the time frame for sync, the sensor will return true. You can confirm that no data is currently syncing by going to the Data tab. If you are not in the time frame for sync, adjust the configuration of your sensor. Then check again on the Control and Data tab to confirm data is syncing.
