yes, I have currently 2 lightbulbs (Phillips and Ikea) and one plug via zigbee attached to Amazon Echo and since about 4 weeks it does not work anymore in OpernHAB, presumably because Amazon changed it’s protocol. Here is the problem I opened in the forum regarding this problem:
Amazon Echo Control Problem: getSmartHomeDevices fails: GET url 'https://alexa.amazon.de/api/phoenix' failed: Too Many Requests .
The interface between the OpenHAB binding and Amazon seems to be pretty brittle in general.
