1 and 3: intriguing.
replyWith 2, I'm trying to think how effectively it could replace something like ESPresense. With that you've got a BLE tag with an ID that you can just associate with a person, so there's no learning of moving patterns needed, but getting it to be accurate to a room is a nightmare. It also works when there's no movement, which is convenient, and you can put the tag down if you don't want to be tracked. The ergonomics are just a bit nicer, it's just the resolution that sucks.
ESPresense and TOMMY solve different problems right now. ESPresense tracks specific people with IDs (even when stationary), while TOMMY detects anonymous motion across zones. For your use case, ESPresense is probably the better fit currently. Though once stationary presence detection is added (Q1 2026) and person identification, it could do similar tracking without needing physical tags to carry around.
replyAh, I was hoping (at least rough) coordinates were something that this would do. I have HA and have been looking at mmwave devices for that use case. For things like "turn on a light, but only once I've sat down in the chair."
replyUnfortunately it doesn't support this yet. But it's on the roadmap and something I want for my apartment.
