Minty Button
I did a hack with Amazon Dash for remote control my RPi based poorman's Nest in 2015.
It inspried me to make a button as "configurable controller", and so the Minty Button in a mint box.
Minty Button was created ahead of Amazon's AWS IoT button.
Of course, my Minty Button is mainly configured to do remote control of enterprise applications. It was even used by an Oracle executive to play a magic at a Conference Speaker session:)
