@swen Thanks for the hint. But I avoid native Alexa support on the devices.
I’ve a more holistic concept to provide Alexa support for all (supported) devices: every device is centrally included in pimatic and then provisioned via the ECHO plugin
There I can choose which devices should be controlable via Alexa and which not.
Native Alexa support is only realized on top via ioBroker (iobroker-pimatic adapter but optional from operational perspective) e.g. for Spotify
