Im in the process of setting up some home automation and have been weighing the pros and cons of Siri vs Alexa. Currently running Homebridge on my raspberry Pi to control my nest, kwikset lock, and wemo lights. I now see Alexa can control wemo switches so considered switching to that until I had the idea of an old iPhone plugged into a Bluetooth speaker with mic always on to mimic the affects of Alexa. Has anyone tried this before and if so how successful was it? Side note: if you haven't heard of Homebridge I highly recommend checking it out on Github. Really fills some gaps in device compatibility.
