You should be able to use their app to assign a reserved dhcp ip address to the HDHR tuner, so it's IP address doesn't change.
Settings > Network settings > Reservations & Port Forwarding

Try this instead Using the IPv4 address instead of hostname of the tuner

While we're waiting for the official SD reply, I've been running this script from my always on NAS for the past 10 days.
It appears that this keeps the background scans from happening on my CABLE HDHR Prime, but I can't be sure since my lineup doesn't change like yours does.

Curious it it keeps the ...

Ran the script for 7 days, which queries the tuner every 5 minutes for scan status and never saw a background scan.

Does this query curl -s http://192.168.1.7/lineup_status.json expose the background scanning when it happens?

Or does running the query itself curl -s http://192.168.1.7/lineup ...

You must still be using a tuning adapter to get channel scans to complete in 7-10 minutes.

Nope. Just Comcast/Xfinity and Motorola cable card. No tuning adapter.
Took almost 10 minutes when I had 530 channels, now that I downgraded to the Choice package it takes about 7 minutes to scan 206 ...

Background scans happen every 72 hours (+/-12), so every 60-84 hours.
Supposedly also happens after power up.

On my HDHR Prime the scan takes 7-10 minutes and uses all three tuners.

You can query the lineup_status.json to see if a scan is running
NOT RUNNING returns {"ScanInProgress":0 ...

Does the background scan timer get reset when a manual scan is run? I could fire off a daily lunchtime manual scan via script if that would block the background scans.

I asked about the same thing for an HDHR Prime and never received a reply from support.
I would also like to know. Guess the ...

This is what I meant by using the "command line utility"
C:\>"C:\Program Files\Silicondust\HDHomeRun\hdhomerun_config" 1323AADB set /tuner2/vchannel 706

C:\>"C:\Program Files\Silicondust\HDHomeRun\hdhomerun_config" 1323AADB get /tuner2/status
ch=qam:129000000 lock=qam256 ss=96 snq=100 seq=100 bps ...

I'm not sure I understand your suggestion.
The hdhomerun_config application accesses pretty much the same information, so I don't see how that would be a better solution. Unless I'm missing something...

If you use the hdhomerun_config application to tune a frequency or channel and to get the ...

If you just want signal stats, why stream?
Why not use hdhomerun_config

I don't mess with PowerShell

On Windows, try this from a Windows command prompt (Windows command line) Works on Windows 10 Pro, not sure about Windows 11

It should contain as many as necessary.
