Hi!
I would like to get the Echo Control binding installed. But I do not even seem to get past the very first step.
I am running Openhab 2.5.8-1 and first tried with the binding via PaperUI.
After install I create an account thing and call the link for this acount offered via the “/amazonechocontrol/” link.
It starts the Amazon account registration process and I get a text to my mobile asking for authorization.
Before I even have a chance of approving on my mobile the PC screen cycles back to the initial login page that now has no credentials anymore. This can go on forever.
I tried to approve faster 
but obviously no success.
I changed to the 2.5.9 snapshot of the binding, but also no success.
Anybody has got a hint why I am stuck here?
