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.
