Is it possible for an appliance to have multiple friendly names say like an array or something?
Hi @stellargo and thank you for your message.
It is not possible to give multiple firendlyNames to devies. If you think this a missing feature from Alexa, you can go here and post a feature request in our ideas space.
I needed this feature too and managed to make it work in my smart home skill controlling Domoticz. I have a description field for each endpoint device that is read during discovery and if it contains the text 'alternate' then the endpoint is cloned with all parameters the same except the second friendlyName is used and a -2 is appended to the endpointId. If my skill needs to control a device it first strips the -2 from the endpointId before calling the endpoint handler. That way, the original device is controlled using the second friendlyName.
