Can you explain what the "Amazon branded wiretap for alarms" is? I did some searches with those terms but can't really understand what you're referring to.
To use them for alarms I just have to say “Computer, set an alarm for 8 in the morning” repeatedly until the damned things understand (I swear they understand a snarky tone far better than when I speak more neutrally (except when Lt Cmdr Data is on TV, they listen to him first time every time!)).
