DirectTV Satellite at home / streaming at my cabin

AFAIK not at this time DTVhelp says they are adding access to the Genie DVR to the new DTV app that is combining DTV sat service with the streaming service. 

Sorry, no. You can't access your satellite DVR remotely. But you should be able to live stream some channels using their Apps and your DirecTV account login credentials. 

Also download the Directv app to your smart tv’s, it should also give you access to most channels in your package.

Sandblaster- are you sure?  This is why I am asking the question, as that doesn’t work for me.  Are you a DirectTV dish subscriber?  If so, have you tried your recommendation on a smart tv at a location that doesn't have a box?  If it worked, could you exactly define which app?  Thanks!

Thanks Juniper - I am specifically looking for the Tennis Channel, which is over $100 separately.  I will call Directv and ask about this.

Unless they have removed the functionality from the Directv app, yes I’m sure. I have the Directv app on an Apple TV, not a smart tv and admittedly not used on on a streaming device away from home but it’s supposed to work.
