I did this a few years ago (sans plugin) and correlated weather to velocity and WIP (Jira) for our development team. I was disappointed to find no meaningful correlation.
Another fun thing this data collecting showed me was subjective bias of certain managers. One of them was sure that a certain hosts were getting much less calls than the others during the show but the data showed that besides one "star" all the hosts have about the same amount of calls even though it "felt" like they got less.
