Hi Etienne,
The quality of the references you shared is exceptional. I was not
successful in finding them with the search terms I had used.
Thank you for sharing your data analysis, observations, and thoughts!
While I do not have prior data, I would be happy to set up HiveMinder
sensors and share the data, and would welcome some guidance.
