How to update all VirtualDevice values?

[kickus]

I'm parsing out the values from the virtual device values from the /ZAutomation/api/v1/devices page (since it has a convenient format). I will regularly collect measured electricity data (via polling), and the data will be logged elsewhere.

I'm aware that the virtual device values contains the some cached values, and an update of the values need be requested explicitely.

I know how to request update from each z-wave device separately by sending update commands to respective device. But the expert ui includes an interesting "update all" button, which function I would like to access through http request. How is it possible?

I'm accessing the data and http from a bash script. Can you advice me how to request update through a bash script?

The zway controller may have more recent measured values than the virtual device api includes, is it possible to access that data from virtual devices without requesting over the z-wave network?

Thanks in advance!
