Refresh Interval
The Refresh Interval defines how often (in seconds) the widget queries its data source. It is configured in the Card Design step on all widget types.
MQTT sources do not use this setting. MQTT-based KPIs update in real time. The refresh interval only applies to database (PostgreSQL, MSSQL, MySQL), REST API, and Excel sources.
How to Access
- Navigate to the Card Design step in the wizard.
- Find the Refresh Interval field under General Settings.
- Enter a value in seconds.
