I would be interested in seeing something like this.
I recently had some poor recording and I tracked it to signal strength.
The symbol quality was cycling from 40%-80%. After rebooting my
hdhomerun the issue went a way and I get a 95% symbol qualify. It would
have been nice to have this monitored in some fashion.
I too am using munin. I guess I would just like some insight on how
best to do this. I am assuming I would poll the hdhomerun for every
channel that I receive periodically, and then graph those results.
I wonder how often is often enough and how much is too much.
