Has been using the Alexa node (local) node for a while, however as many of you know, the Alexa local node does not work now, unless you redirect ports etc...,
So here is another work round I did which works a treat.
- Setup IFTTT:
1.1 Create new applet with Amazon Alexa service
1.2 type relevant control phrase eg "on sonoff"
1.3 Create action with adafruit.io, with your feed/name and data (eg 1)
Repeat for "off" control
Only slight inconvenience is you have to say "trigger" before the phase. e.g:
"Alexa, trigger on sonoff"
