Go to your setup page by clicking on your system size on you live page. Scroll down until you see these settings and click on the “secondary device” and see this for the supported devices:
If you don’t see your device you cannot use this option and you will need to use another method such as a Raspberry PI or similar single board computer which you can program to do the auto uploads. The Raspberry PI is open source, costs about $25US and the operating system, Linux, is free. I use Debian on mine. There are online sites such as GitHub.com
which is also free and you can search for others who may have already done the programming for you.
Since your youless does not appear in the list it is not supported. Here is a link to a GitHub project for the youless. You may have to join GitHub which is free to see the actual project. There are a lot of helps on the site for non-programmers.
