Just got my Echo Dot V3 and after linking Alexa with SmartThings, I can see the SmartThings devices such as contact closures, smart plugs, and thermostat in the Alexa app. Here is where the fun begins… I am just starting but I want to share what I know. You can create routines in Alexa to announce door and window once it is opened by asking Alexa to say it in the routine. The Alexa response time on ST events is quite impressive! The pain here are: 1. You have to do one routine for each contact sensor… >>>This is not as bad since you can customize the text you want Alexa to say. (For now, I ask Alexa to say “close that door” when I open the front door—for fun) 2. Alexa speaks too fast and sometimes you can’t make out what was said (try dining room window opens) >>>As with any text to speech program, there are rules must be obeyed. Alexa also follows sentence structure rules. Those rules are : “space”, “comma”, “period”. Each one of these have some delay value associated with it. Such value is depending on what you want the “text to speech” process sounds like. >>>Ok, multiple “spaces” will be reduced to one. This is expected since Alexa is to read the news from some where… >>>”comma” and “period” have longer delay so you can use it to control Alexa speed (try dinning, room. window, opens) Have fun.
