I tried controlling Alarm.com’s lights and locks using an Amazon Echo Dot. The functionality works, but it’s more cumbersome than it should be and misunderstands the commands a lot of times.
I was able to lock (but not unlock, as it’s not supported) door locks (individual ones or all at once) and turn lights off and on. I was also able to ask if my door locks are locked or unlocked, but the recognition is really poor and it took several attempts for it to understand which doors I was talking about.
I was also able to arm stay, but arm away and disarm are not supported.
I don’t have a smart garage door but I’ve seen a demo of it working, so it’s supported.
Since I have a Nest thermostat, and it’s not currently compatible with Alarm.com, I wasn’t able to test that either, but I’ve seen it working.
So, all in all, a good start, because the integration at least has smart home support, but I probably won’t use this.
P.S. It says “U office light” because I named it that way in my system (U for upstairs).
