Possible to get signal strength to show

[bossanova808]

I am wondering if it is possible to get the signal strength to show up in the Kodi UI with NextPVR?

Currently, it does not...I can see, in my logs, signal strength and quality are there at the NextPVR end of things (e.g. below, strength -16, quality 25)...but clearly they don't make it to the Kodi UI (Matrix 19.4, have checked in both Estuary and Confluence, both show 0 for both the SNR/Signal Strength fields).

Hardware at the server end is a Win10 machine with a Hauppage twin tuner thing in it.  Clients are ODroid N2 machines running latest CoreElec (19.5rc1), or Win10 running Kodi 19.4)

No, the NextPVR API doesn't support it. Even if it did, I don't really see the value of polling the server every second during live TV, so I wouldn't add it to Kodi myself. Many tuner types don't provide this and sometimes the digital tuners that do report crazy values. Even when it is correct, typically you can tell during live TV when the picture is poor without an OSD. If sub added the API, someone else would be free to submit a PR but I would ask for it to be configurable.

Ok, fair enough I guess. It wouldn't bother me if it were just the initial values at the point of tuning (vs polling, although I have written other things using Kodi and polling and once a second is not impactful even on very low end systems in my experience, and of course you could make it every 5 or 15 or whatever...).

But it's a moot point at the Kodi end of things anyway, if there is no NextPVR API for it, of course.

Thanks for the reply.

Kodi polls NextPVR which would have to poll the tuner service etc. The OSD to show the O screen can actually slow down the system more than the poll on some systems.

For debugging which I see as the main purpose, it is already logged. For Kodi, it would think Ctl-Shift-O dropped frames in Live TV and in Recordings would be more helpful.
