Virtual device shows null value


after I originally backed the kickstarter project for homey and sold my homey because of the frustrations which came with it (in the early beginning), I decided to give Homey another go and bought a new one.

So at the moment I’m working on creating my Homey Dash and installed a plugwise smile today.
I want to be able to show multiple values on my dashboard (actually all the values plugwise provides).

The values are available in my flow, but when I want to assign this value to a virtual device it shows NULL.

The actual values are showing up in simple log but I can’t assign them properly to my virtual device.
What can I do to get this working? Am I doing something wrong or ain’t it the way to go?

Thanks in advance.

and the flow looks like?

Trying with some testdata at the moment.

You should use measure_temperature instead of “Temperatuur” in the last card (TestVD - Thuis). That is the way that Homey works. See this page for more information.

You need to use the capability ID (which you can find here)

What’s very important is with which capability the device was created, I assume you choose a thermostate type, but which capabilities did you choose after that?

It will only work if you selected the appropriate capability and set that one in a flow.
