I didn't realize you need to pay to use that thing. But well, that is why people make program to make money.
And to the OP yes of course you can do anything you want with Alexa. But you do need to make it your self if you don't want to pay.
AWS account is not free as far as I know or I would have created an account already and make custom skills for my echo.
I know AWS ACCOUNT is free to make but you need to pay for server use.
no i have not checked the link yet
yes the AWS is not free technically but it is virtually free you can make your own skills and just publish them personally to yourself it is only if a skill is made public and accessed a ridiculous amount of times that it will become pay, you would have to access the skill like 1,000,000 times in one month to be charged anything lots of people are using the custom google and youtube skills such as myself
you just create an account and make the skill and then do not publish it to anyone but your account
ok i just checked the link ,seems you are not good at comprehending what i am looking to do here
i want to be able to cast music FROM my alexa /echo dot TO my DLNA receiver
as well as have it be able to access music from a DLNA server
this would do half of what i want, i specifically asked if it was possible to do the reverse
maybe i am not making it clear enough
it would work like this , "alexa ,play radiohead radio" " getting your radiohead radio station from pandora, radiohead radio"
then i would be able to tell alexa to play in another room using the whole home audio feature but instead of just being able to tell it to sync the audio to other echo devices or sonos speakers i would be able to sync it with a DLNA enabled receiver
like i can use UPnP on my android tablet to cast audio FROM my tablet TO my DLNA enabled AVR
i run UPnP on my rooted 2015 custom rom fire tablet ,which runs android , the dot also is running a form of android
so it should be technically possible hardware wise to have the dot cast whatever audio it is playing via DLNA TO any DLNA enabled receiver , but with AWS i am pretty sure you can just create skills that run in the cloud and not on the actual device , but i am unsure about this , the code to be able to do this would have to be run on the device itself not in the cloud i would think
