It’d drain the batteries quickly. Wifi uses a relatively large amount of power, and low-power wifi variants like HaLow aren’t widespread yet. Bluetooth has a low energy mode for low-power devices that works well for this use case. I guess it could have a power cord, but then why use wifi when it could just plug into the phone instead?
Why is there no wifi cassette adapter? That would be so cool.
