Enable SDR to HDR tone mapping via command line

[sorted01]

Hey Awawa!
first of all thank you for your awesome work! 👍
A short introtuction for my question:
I am using IoBroker to control my smart home. Within that I have the Linux control adapter which can send commands to the raspberry.
Is it possible to enable & disable the SDR to HDR tone mapping by such an command?
My idea is to create a virtual button which can be triggered by a button/voice/whatever which sends a command line to my raspberry that changes the tone mapping.

Thank you!

EDIT

in the issues i've found this answer from you:

- platform: command_line
switches:
hyperion_toggle_hdr:
command_on: curl -X POST -i "http://192.168.178.92:8090/json-rpc" -d '{"command":"videomodehdr","HDR":1}'
command_off: curl -X POST -i "http://192.168.178.92:8090/json-rpc" -d '{"command":"videomodehdr","HDR":0}'
command_state: curl -k http://{IP_OF_HYPERHDR}:8090/json-rpc -H 'Content-Type: application/json' -d '{"command":"serverinfo"}'
value_template: >
{% if value_json.info.videomodehdr == 1 %}
{{ true }}
{% else %}
{{ false }}
{% endif %}

Am I right with that: To control it I only need "command_on" and "command_off"

Having the current state within IoBroker would be a nice to have. But therefore I guess I have limited knowledge of how to put the outcome of "command_state" into an IoBroker datapoint.

Hi
Yes, you can control HDR settings with the commands that you have included.

API address:
http://{IP_OF_HYPERHDR}:8090/json-rpc

To set HDR tone mapping include JSON in the videomodehdr request (HDR: 0 - off, 1 -on). For example:
{"command":"videomodehdr","HDR":1}

To get the state of main components send:
{"command":"serverinfo"}

The result of serverinfo command returns a json. Home Assistant (https://www.home-assistant.io/docs/configuration/templating/) can automatically parse it to value_json from the above example so to extract a HDR property from that object you can simple refer to value_json.info.videomodehdr Unfortunately have no experience with ioBroker and could not find a parser for json but it offers regex parser that probably can extract that value in somehow unconventional way (ignore json structure and treat it as a text): https://github.com/ioBroker/ioBroker.parser

So for following result from the HyperHDR:

you should use regex:
"videomodehdr": (\d)

to assign the state of HDR tone mapping to the final regex group (tested on https://regex101.com/):

Hey, it's me again. Thank you very much for your feedback. Such an detailed answer! But... Before i get the output working I would need again some help with the control itself. :/ Sorry I am a real newb in using Linux...

As I did want to test it upfront I tried using the command line from above within PuTTY leading to following error:

pi@HyperHDR:~ $ curl -X POST -i "http://192.168.178.92:8090/json-rpc" -d ''{"command":"videomodehdr","HDR":1}''

HTTP/1.1 200 OK.

"success": false,

}

This showed up within the HyperHDR Logs:

Again sorry for asking supid questions. But maybe you can support me once more ;)

No problem. I'm working on make the request easier but I'm not promising anything for the moment.
For your problem there are some unnecessary (doubled ' ) chars after "-d " and at the end of the command
Try this:

curl -X POST -i "http://192.168.178.92:8090/json-rpc" -d '{"command":"videomodehdr","HDR":1}'

Thank you so so much! It works like a charm! :)

EDIT:
I've updated the commands in the initial post. So that no one will copy that miskake
