How can I use the Roamio without a mobile device?

I'd like to use a Roamio to stream Comcast from a Comcast DVR to another TV that does not have the Comcast equipment on it.

I want a receiver that has a remote, that I can change the channel with, I do not want to have to connect it to an app on my phone and hand off, or anything like that.

What are my options?
