Pironman5 command do not work

Hello everyone
Raspberry Pi 5 8GB +SSD 128GB + Raspberry Pi OS 64bits
I installed Pironman5 without any problem. The pironman5 command works with sudo :
pi@raspberrypi:~ $ sudo pironman5 restart

pi@raspberrypi:~ $

but when I run a command to turn off the LEDs or to change the colour, modify the operation of the fans, nothing happens even though the system does not return an error.

pi@raspberrypi:~ $ sudo pironman5 -re false
pi@raspberrypi:~ $ sudo pironman5 -rc ff0000
pi@raspberrypi:~ $ sudo pironman5 -rc 00aabb
pi@raspberrypi:~ $

nothing happens…

Modifications from the web dashboard work perfectly.

Does anyone have any ideas?

You also need to execute the command to restart the pironman5 software after using the pironman5 command:
sudo systemctl status pironman5.service
Your data modifications will only be successful.
