Unless you can convince your cable company to publish a proper list of channel mappings (unlikely), you are not missing
anything, that is what you will have to do.
Usually, my cable company only changes a couple of channels at a time, so I only have to rescan the channels that changed. You
can use "HDHomeRun Config" to see if the channels have changed by recording which channels are where and checking from time to
time. You may be able to automate this check as well, though on demand channels will make grep difficult, and you won't know
where channels have moved to, only that they have moved.
Scte65scan can generate a list of callsigns to frequencyID to cable company channel numbers, but it is only good for limited
basic SD channels, and includes a bunch of encrypted extended basic SD channels. It does save some time trying to figure out
what the channels are.
Also SiliconDust.com has local channel mappings that may help, though they are not always accurate.
