JSON commands for smoothing parameters

Marxon · Mar 29th 2025

Hi Hyperion-Team,

currently, you can only enable or disable Hyperion's smoothing feature via JSON.

It would be nice if you could set all the smoothing parameters (type, time, etc.) via JSON.

Best regards

Hi

with the current development version you can update the configuration too.

As these are Admin commands you need to create an API Token under Network.
Replace "HyperionToken" in the command below via your token.

In case you are executing the command on a different host, replace localhost by the DNS or IP of the host Hyperion runs on.

You can query your current smoothing configuration via

JSON

curl -X POST -H 'Authorization: Bearer HyperionToken ' -i http://localhost:8090/json-rpc --data '{
"command": "config",
"subcommand": "getconfig",
"configFilter" : {
"global" : {
"types" : [""]
},
"instances" : {
"ids" : [],
"types" : [ "smoothing" ]
}
}
}'

Assume you would like to update the smoothing configuration for instance 0 you can achieve this by sending

JSON

curl -X POST -H 'Authorization: Bearer HyperionToken' -i http://localhost:8090/json-rpc --data '{
"command":"config",
"subcommand":"setconfig",
"config":{
"instances":[
{
"id":0,
"settings":{
"smoothing":{
"decay":1,
"dithering":false,
"enable":true,
"interpolationRate":25,
"time_ms":150,
"type":"linear",
"updateDelay":0,
"updateFrequency":25
}
}
}
]
}
}'

To test with the development version see here: https://docs.hyperion-project.org/user/advanced/Testing.html

Thanks for your reply Lord-Grey!

This is already possible with the hyperion nightly build?

Really nice!

Because i'm watching dj-sets and concerts frequently and there i prefer different smoothing settings

than for watching movies. So i want to switch easily between two smoothing setups via remote button.

Is there a something like a nightly changelog on github too?

Best regards

Lord-Grey · Mar 30th 2025

In the unreleased section you find the changes included in the nightly build.

hyperion.ng/CHANGELOG.md at master · hyperion-project/hyperion.ng

The successor to Hyperion aka Hyperion Next Generation - hyperion-project/hyperion.ng

github.com

The PR I was referring to has some additional corrections. For details see here:

Would be great, if you could test against the PR.

You can install the PR version next to an existing one and remove it after testing.

Marxon · Mar 30th 2025

That's a lot to study and test!

The installation went smoothly without problems on my LibreElec.

Let's see if mapping the remote will go like it too...

Hi again,

unfortunately the development version respondes

error: No Authorization

Creating a new token does not help

What I don't really understand is the -c option for installing the PR:

the config seems to be copied anyway when executing the PRID.sh

Best regards

What I don't really understand is the -c option for installing the PR:

The -c option allows you to specify the directory where your current’s hyperion configuration file sits.

This configuration will be copied to the PR directory created during installation and used when you start via the PR script.

That only happens if the directory provided exits. See https://github.com/hyperion-pr…cripts/install_pr.sh#L258

If you do without -c a default configuration will be created.

Have you checked that you run the correct Hyperion version?

Go to System/About and check the build includes the PR number.

How do you pass the command and the token?

Have you tried to run the command from the same host?

Just to be on the save side. The token is not the GitHub one, but one you need to create in Hyperion under Network.

Hyperions Dashboard shows me 2.0.17-beta.3+PR1849

Yes i do so.

The getconfig command was working before on 2.0.16 with the following command:

curl -X POST -H "TOKEN" -i http://localhost:8090/json-rpc --data '{

"command": "config",

"subcommand": "getconfig",

"configFilter" : {

"global" : {

"types" : [""]

},

"instances" : {

"ids" : [],

"types" : [ "smoothing" ]

}

}'

EDIT:

Sorry I was wrong.

Tried the getconfig command on 2.0.16 again, result:

(ERROR) While validating schema against json data of 'JsonRpc@::ffff:192.168.1.10':[root].configFilter: no schema definition

Marxon · Apr 4th 2025

I am such an idiot!

I left out the two words Authorization Bearer befor my token

Now everything works like excepted!

Sorry sorry sorry!

Lord-Grey · Apr 4th 2025

Good to hear that it is working now!!!

In case you have other findings with the development version, happy to hear.

Marxon · Apr 4th 2025

One last question:

how to autostart the development version in kodi?

Did it.

createt this hyperion.service file:
[Unit]
Description=Hyperion ambient light systemd service for user %i
Requisite=network.target
Wants=network-online.target
After=network-online.target
After=systemd-resolved.service
[Service]
ExecStart=/storage/hyperion_pr1849/bin/hyperiond --userdata /storage/.hyperion --service
WorkingDirectory=/storage/hyperion_pr1849/bin
User=%i
TimeoutStopSec=5
KillMode=mixed
Restart=on-failure
RestartSec=2
[Install]
WantedBy=multi-user.target
Copied this file to /storage/.config/system.d/
Run systemctl enable hyperion.service

Lord-Grey · Apr 7th 2025

Marxon We did some further corrections and the development version and now publish it via the Nightly Build channel.

So you could run and test it without modifying the systemd service file.

Marxon · Apr 18th 2025

Thanks for this Infomation Lord-Grey.

Embarrassingly i'm not getting the nightly build installed on my LibreElec.

I also tried Paulchen Panthers script with --nightly option but GibHub release installation does not support nightly releases.

Lord-Grey · Apr 18th 2025

What does the install command say?

Code

curl -sSL https://releases.hyperion-project.org/install | bash -s -- --nightly

Could you share the output?

Note: If you have already installed hyperion, you need to remove that one first.

… but that is reported by the install script

Code

curl -sSL https://releases.hyperion-project.org/install | bash -s -- --remove

To some extent I already did This is the exact output:

Pi4:~ # curl -sSL https://releases.hyperion-project.org/install | bash -s -- --nightly

INFO : Identified distribution "libreelec"

ERROR: GibHub release installation does not support nighly releases.

Lord-Grey · Apr 19th 2025

Sorry, I forgot that LibreElec is not working with apt packages. My bad!

There is currently PR 1856 open.

You could test with that one benefitting from further corrections

Marxon · Apr 19th 2025

Allright!

Marxon · Apr 27th 2025

Hi again!

I may have found a new problem. But I'm not sure if it's related to your PR.

I'm using an Android app (Hyperion Control) that previously worked without issues, but now doesn't.

The app was also not updated in recent times, so i guess it must be related to Hyperion.

The log shows the app starting:

2025-04-27T11:13:23.027Z [WEBSOCKET] (DEBUG) (WebSocketJsonHandler.cpp:22:WebSocketJsonHandler()) New WebSocket connection from ::ffff:192.168.1.6 initiated via:

2025-04-27T11:13:23.028Z [WEBSOCKET] (INFO) JSON-API service is ready to process request

But it does not react on any changes.

Any ideas, "Mr. Lord-of Code-Grey"?

Lord-Grey · Apr 27th 2025

I latently applied some further fixes.

Depending when you installed the PR, there were issues.

I now merged the PR and I do not remember, if the script loads closed PR executables.

Maybe you can give it a try

Marxon · Apr 27th 2025

I guess you mean i have to install the nightly build (scripts aborts because of closed pr), right?

Unfortunately i am using LibreElec and it is not working with apt packages.
