One of the things I tend to do at least once a day is to open the Channels DVR site on my phone, and look at the DVR tab to see what's recording tonight.
I was thinking it would be cool if I could just ask Siri (on iPhone or my HomePod) what was on tonight...so, I built a shortcut to do just that. Here's a screenshot of it after running on the phone; I didn't upload a video, as I think you'll get the idea:
The shortcut requires iOS 13. It should (hopefully) run on HomePod as soon as it gets its 13 update, hopefully later today.
Here's a link to the shortcut:

When you first run it, it should ask for the IP address of your Channels DVR...beyond that, there shouldn't be any setup involved.
Also FYI, I couldn't find any documentation about an API and such on the DVR - so this is all likely to break at some point, use at your own risk, etc...
