In the latest DVR build v2019.11.08.0102 we have added a new log entry that appears at the end of every recording showing the HDHR signal levels measured while that recording was happening. We hope this is helpful in tracking down a common class of recording issues.
[SNR] Statistics for "TV/KEYT NewsChannel 3 at 5PM/KEYT NewsChannel 3 at 5PM 2019-11-07-1700.mpg": ss=78%/78% snq=100%/100% seq=100%/100%
Each metric shows a min and max value. The numbers are polled every 10 seconds while recording. This feature works with all non-legacy HDHR units, and requires the latest stable HDHR firmware 20190621.
(For an explanation of what these numbers mean, see https://info.hdhomerun.com/info/troubleshooting:signal_strength_quality)
Please try this out and report back on how it works for you. Once this is deemed stable, we plan to surface it up further into the apps and flag recordings which were made during poor signal situations, and also eventually show signal warnings in the player when watching live tv.
