Polling Settings

Introduction

Polling is the process where Vera requests information from a Z-Wave device about its current status, such as on/off, dim level, temperature, and so on.

Depending on the device, polling may not be necessary, as the device will report any status changes to Vera autonomously. Those devices are not normally polled, but only when Vera starts up.

Other devices, such as many battery operated sensors for example, will be in a very low-power state most of the time and therefore cannot be polled at all.

The polling mechanism and the parameters that control it, are described in more detail below.

Settings

The highlighted section in this screenshot shows the poll settings for the entire system. They apply to all devices, unless specified differently for a specific device.

• Poll nodes
  Master switch to enable or disable polling.
  
• Number of seconds to wait to start polling <#>
  Number of seconds after Vera / the Luup engine has (re-)started before the polling mechanism begins.
  
• Only poll a node if the Z-Wave network is idle at least <#> seconds
  Number of seconds Vera must not have transmitted any non-poll command before the next poll command is sent.
  
• Poll a node every <#> seconds.
  Number of seconds between poll commands.
  
• Unless specified otherwise, poll each node at most once every <#> seconds.
  Minimum number of seconds between poll commands to the same node.
