Hey @quietminded, thanks for your question, and very sorry that our support team never got back to you! Would you mind logging into the support portal (https://help.sense.com) and checking on that ticket and resubmitting it so they can get you a proper answer!
Big thanks to @jasonemoyer for doing a great job of answering your question. We have had some detection issues on mini-splits in the past, but the team is aware of them and working on solutions. We actually have a lot of people here in the office with minisplits (and Sense of course!) in their homes, so it’s at the top of their mind!
