Unfortunately, since smarthome/j isn’t part of the OH project you will probably have a better chance at support by filing an issue on the smarthome/j repo.

i couldn’t found smarthomej in my binding list :frowning:

No, Smarthome/J is the third party marketplace where the Amazon Echo Control add-on appears to come from.
