In my last post I tried to explain how to access your IoT devices at home from the Internet in a secure way using a reverse proxy. Truth is that I had it running since maybe 6 months ago without giving it too much use until recently. Reason? My Nexus 5 had been having serious problems (battery not charging, screen broken, earpiece not working,…) and I decided to replace it with a new mobile phone and the new one has Google Assistant built in.
So one of the first things I have tried is to make Google Assistant toggle my smart switches flashed with ESPurna. Nad as it turns out it’s not hard to do but -at the moment- you have to relay on a cloud service like IFTTT (IF This Then That). This is a key difference with Amazon Alexa services you have to be aware. It has some benefits but also some drawbacks.
My daughters love to talk to (or with) my Amazon Dot [Amazon US] in their funny English: “Alexa, hello!”, “Alexa, li-on!” (actually “light on”). It’s so easy to use it to switch on/off things at home using the fauxmo python script by Maker Musings. In his post about Amazon Echo and Home Automation more than a year ago he explains how he reverse-engineered the protocol of the WeMo switches that Alexa (Amazon Echo [Amazon US] or Amazon Dot [Amazon US]) supports.
I also have a server running the fauxmo script with an MQTT handler to control some of the Sonoffs I have at home, but this morning I woke up thinking: why should I use an external script to control my devices if I can code it in the firmware?
