Ah yes, I forgot to mention that bit 
.
As far as I know, the remaining time of the timer is not directly available as a tag. Instead, I am using an Enhanced Virtual Device that includes the remaining time as a capability.
In an Enhanced Virtual Device you can select timers/stopwatches from the Chronograph app as a source for capabilities.
Next, in the flow I use a WHEN card from the Enhanced Virtual Device app, that triggers when there is a change in a capability, as the trigger for the DataVista Label widget. In this case a change in the remaining timer value:
That card also provides a Value (‘Waarde’) tag that holds the current value of the changed capability. In this case the remaining timer value.
