Hello,  
I try to control my lights via xiaomi aqara cubes.  
At the moment iam stuck with the usage of a functionscript which is calling an actionnodes multiple times for webrequests. (I need the state of my hue-lamps)  
The call is working fine, but iam not able to use my results from the webrequest in my nodes.  
Is there a way to wait until my webrequest is finished?

```
