Hi
I have Freesat TV Tuner and it does not pick up all the channels in unraid .
When I use it a windows OS I can get all the channels.
When is Plex going to give us more control over fine tuning and renumber (add more channel to are tv tuner list
Satellite is not supported by Plex and I personally doubt they would add it now https://support.plex.tv/articles/community-supported-tuners/
Note sure why so many people say they are not āsupportedā, I have 4 DVB-T and 2 DVB-S Tuners on plex working. I use the DVB-S in the UK to get HD Versions of Quest, ITV2,3,4.
For the āall channelsā bit make sure you have updated the transponder list. I am assuming you are UK hence freesat so need to update 0282.ini the Astra transponders.
To updated transponder 0282.ini I use this site Satellite directory - KingOfSat
I use the following commands, (I am not great at unix !)
cd /usr/lib/plexmediaserver/Resources/Tuner/Shared/scanners/dvbs/transponders/
sudo cp ādl.php?pos=28.2E&fkhz=0ā 0282.ini
To control the channels I choose āAstra FTAā and manually fix the assignments āThis takes awhileā.
Then select the channels you want as favourites.
Then in favourites you can re-order.
So it is possible but not exactly straight forward.

Just repeating the official line from Plex, not saying you canāt hack it together 
Yes I saw that when I was looking into this.
Note that at the bottom of the Article it states āLast modified on: October 31, 2020ā and āItās something we are investigatingā. So to correct your doubt and inform the forum, they did investigate and it does now work.
Well for me anyway 
I donāt think itās a hack, itās just an update to the transponder list as they seem to be very old. I update my PMS from the beta stream and the transponder lists have headers like [ downloaded from www.kingofsat.net (c) 2016-04-26 14:08:31 ]. So are not being updated by plex when releasing PMS.
Would be interesting to get an update on that Article, as not sure what āthe official line isā as apart from the old transponder lists it working.

I did sort of get it working myself with a TBS DVB-S2 tuner but found it was trying to subtitle or produce wrong audio so gave up and bought a HDHomeRun which has been great.
Iām using unraid and still learning.
Iām not getting any BBC, Channel 4, Channel 5 and all other channels
all Iām getting is 62 channels.
when I use windows I can scan around 800 Channels
I sorry for being so Thick
It looks like your hardware is working but you are unable to scan for all freesat channels.
My setup is different , I am using āHauppage nova s2 dvb usbā and running ubuntu 22.04, on an intel N100, all I can suggest is that as we are both using plex media server (PMS) then try to updated the PMS transponder list.
The default PMS transponder list is very old so unless you update it you will not get all the chanels.
When you selected ā28.2Eā PMS will load the 0282.ini file that contains a list of all the freesat transponders/frequencies.
To update the file you need to open a terminal, find the directory and update the file.
1)Open a terminal.
- change directory to the transponder files
cd /usr/lib/plexmediaserver/Resources/Tuner/Shared/scanners/dvbs/transponders/
- Download the update :
sudo wget "https://en.kingofsat.tv/dl.php?pos=28.2E&fkhz=0"
- Copy the update file over the old file supplied by plex
sudo cp 'dl.php?pos=28.2E&fkhz=0' 0282.ini
- reboot and rescan 28.2E
This is what I did in ubuntu, unraid may be different!
I hope this helps, It can be frustrating but donāt give up.

Thanks for the help. Here are the file lay out that I think is from docker
I am not using docker I installed plex media server directly in Ubuntu
You could try this command to search for the file.
sudo find / -name ā0282.iniā
If it does not show any results, then you may need to open a command shell inside your plex docker image, sorry i have not used docker. 
There should be a subfolder inside the folder with the Plex server executables.
Plex Media Server\Resources\Tuner\Shared\scanners\dvbs\transponders
(the above is from Windows, but it should be quite similar across platforms)
Under Docker with unRAID the files are not in appdata, they appear to be provided on the fly from the docker image.
I accessed them by starting a console session from unRAID into the running PMS docker container, eg:
Iām sorry to be so thick at this.
Can you please do a step by step guide.
From the unRAID Docker tab where all your containers are listed, left click on the Plex container and in the dropdown presented choose Console
this what get when I put pwd

Where does Plex store the configuration information for the LNB-settings for the tuner? The interface already exposes some satellite values (like DiSEqC for example) but is missing values to configure the LNB in a Unicable-setup.
Can you manually edit the config file to change the LNB type to Unicable and enter die Unicable-channel and frequency?
Since there is no support for satellite, there is no support for unicable either.
thanks for the help.
where I live itās hard to get a Freeview signal so I have to use Freesat to get my TV.
