Two different units triggered on the Smoke or CO alarm sound today.
One as I was leaving and arming ADT (via Alexa Guard).
The other when I returned and disarmed ADT.
The only sound it was hearing was the ADT timer beeping the 60 seconds I have to leave the house after arming, or the timer for disarming. That beeping sound has not changed since the ADT service was upgraded and integrated w/Alexa...so you guys have changed & broken your detection mechanisms.
Sort of makes Alexa Guard useless at present.
