Well, even though its highly unlikely that anyone would need this info anymore i’d thought i would share the solution.
As my 10 year old Vera Lite apparently crashed and therefore lost all of it’s z-vawe configuration
I had to start all over.
The Vera accepted devices to be paired again and as i had paired my Fibaro universal sensor and got it to read and display temperatures i now again needed to get the imported to HA.
I actually did make it work the last time around 3 years ago 
But now 3 years later I had not the faintest idea of how i did it.
Turns out you need to set the “category” ID (under advanced settings on the device in the Vera interface) to the correct value for the devices to be read correctly when imported to HA.
For temperature sensors the value should be set to “17” or “1” for the device to be listed under the “Climate” category in Vera.
Then you just need to reload the integration in HA and temp sensors displays fine.
