DVR recording completed notification

Is there a way that I will get a message when a planned recording is completed. Directly from DVR software
or can I get this information via the "Channels API"?
If so, what would this query look like?

My goal would be to send a message via "Home Assistant".
With Home Assisant there are a lot of possibilities, there is even a channel integration as a player.

Did you get anywhere with this? I am also interested....
