Will still be publishing a detailed How-To, but I had to utilize the following:
- Hardware: Amazon Echo
- Hardware: SmartThings Hub
- Hardware: Remotec ZXT-120
- Hardware: Panasonic Air Conditioner
- SmartThings API: Add Custom New Device Type 'ZXT-120 IR Sender Improved'
- SmartThings Routines: 1 Routine to turn AC on, 1 Routine to turn AC off.
- SmartThings API: Add SmartApp 'Virtual On/Off Switch Creator'
- SmartThings API: Add SmartApp 'Alexa Helper'
- A lot of patience for trial and error..
