DVR Commander https://play.google.com/store/apps/details?id=com.arantius.tivocommander seems to not work with the Roamio at the moment. I suspect it doesn't know what a Roamio is but would work fine if it did. Since it doesn't know it, it refuses to connect to it. I Emailed the developer. Will share what I learn. kmttg and pytivo work great!
