What’s the difference between the Smarthome/J Amazon Echo Control (enabled via https://download.smarthomej.org/addons.json) and the OH Amazon Echo Control binding? The descriptions look identical (?). Is one newer than the other? Or has more bug fixes/features?
They are two separate implementations, one of which is a part of OH and the other which is hosted on the third party Smarthome/J marketplace.
I do not use either so I cannot say what specific differences there are but I’m certain there are some.
