Has the state of hobbyist microphone arrays improved? The thing that’s always given me pause here is that my Echo devices are quite good, especially for the cost, at picking things up in a relatively noisy kitchen environment.
A few months back I was playing with BLE tokens and espresence receivers so HA can tell which room I'm in. It was way too noisy to be useful at the time, but it strikes me as something that's eminently doable.
