The main attack vector would then probably be some man-in-the-middle intercepting the signal from your wearable, which leads me to wonder whether you could protect yourself by having the responses valid for only an extremely short duration, e.g. ~1ms, such that there's no way for an attacker to do anything with the token unless they gain control over compute inside your house.
