I can’t commit to the timing, but the fact that it has risen to the top of the list certainly helps in getting it prioritized for further review / analysis.
I did some prototyping work on this a few months back - I’d have to revisit my notes for the details, but I do recall there being some challenges in that initial analysis. For example, there are data structure and API differences between HS3 and HS4 that would potentially warrant only supporting HS4 (at least at first release). And it seems like big chunks of the community are still on HS4 (even though many have paid for HS4 licenses, but not yet migrated).
The other thing I recall seeing is that the data modeling being somewhat weak and would be a challenge in dashboards where we use more standardized classifications. I think there’s room for inference here based on the reported control pairs / states, but I was surprised that even though there is a concept of ‘device types’, most of the devices I tested all reported ‘generic’ types.
