Yes, but it was obvious and I didn’t use equipment. It was in Jan 2020 at an Airbnb “hotel” in Nashville. There were two smoke detectors in the room. One of them was not like the other. I wrapped it in toilet paper. I left it wrapped so the owners knew that I knew, but I didn’t bother reporting it because I rarely used Airbnb and it was a last minute trip. And then the pandemic hit and that was that.
