Alexa as Home Automation Integration Point

Over the past few months I’ve done a lot of experimenting with getting various home automation technologies to communicate with each other. For example, setup a Raspberry Pi to bridge between SmartThings and Home Assistant using MQTT. SmartThings in turned connected to my Harmony Hub. Then tied in my Patriot custom electronics devices via MQTT. What I ended up with worked, but seemed overly complex. I don’t even want to try to blog about how to reconstruct such a beast.

So that got me thinking about how to simplify things. I realized that the individual pieces are are fairly simple: SmartThings, Patriot, Harmony. Each of these provides their own Alexa smart home skill, and most of what I want to accomplish can be done entirely by Alexa. So it isn’t really necessary to try to bridge between each of those. Instead, I can let Alexa be the common interface to each of them.

So that’s what I’m trying now. I’ve removed the bridging pieces, and will be using Alexa to control everything. Things certainly are simpler now. I’m hoping that the recently announced support for Echo Buttons indicates a direction for Amazon that will allow other inputs to be used with Alexa. Amazon is holding to their “voice first” mantra, but we’ll see where this goes.

In the meantime, I’m investigating whether I can trigger an Alexa skill lambda handler directly from a Patriot device. I think it may be possible…
