Awesome use of Alexa!
But, this is interesting.
Do we put our faith in this complicated technology that relies on amazon servers in Kansas and all the networks between our homes, kansas and aquariums to function correctly? I bought an alexa controlled led lightbulb and used it once because it was easier to turn the switch than talk to alexa, have it go to the Chinese website where I registered the lightbulb, come back in via my internet connection and wifi command the lightbulb on.
I dont think the outlets interface direct to alexa, inside your home but rely on a reliable connection to outside and back. It seems like a trivial point until you think about failure modes and making the automation reliable, which is part of the point. No one dies (well the fish) if this fails, but the best automation has fail safe modes, think Apex.
And I can't tell you if when I press feed mode B on the Apex iOS app how that gets to the fusion controller, but that is why I have the local Apex USB control panel.
I guess Alexa is better than nothing, but perhaps (today) not as good as local control.
This is an interesting topic, let us know your experience.
Can we rely on Alexa to control our aquariums?
