I am trying to use the python console to achieve the following manual procedure of setting each layer to refresh automatically at a specified time interval.

The manual process: Layer Properties > Rendering > [tick box] Refresh layer at interval (seconds) > [enter seconds].

How do I do this from the python console?

This specific rendering information is not stored in a style, and manually setting it for each new layer is time consuming. I often reload all of my layers into a new QGIS project, so being able to set the refresh interval rate with python will save a lot of time.

For set this property you need to change its value in the QGIS settings

from qgis.PyQt.QtCore import QSettings
QSettings().setValue("/qgis/map_update_interval", 150)

For set Refresh layer at interval (seconds) using PyQgis you need:

# Get layer by name
layer = QgsProject.instance().mapLayersByName('pipelines')[0]

# Enabled auto refresh
layer.setAutoRefreshEnabled(True)

# Set seconds (5 seconds)
layer.setAutoRefreshInterval(5000)

API reference setAutoRefreshInterval()

  • Thanks for your post. Unfortunately this isn't what i was after. I want to update the refresh interval rate for the layer, not the map update interval. If you follow the path mentioned above: Layer Properties > Rendering > [tick box] Refresh layer at interval (seconds) > [enter seconds]. It is this that i am trying to set from the python console.

    Perfect! Thank you very much. Something worth noting: I found that the setAutoRefreshEnabled(True) only worked after an existing value was assigned to it from the setAutoRefreshInterval. Therefore I switched the order around: 1st layer.setAutoRefreshInterval(5000) 2nd layer.setAutoRefreshEnabled(True)
