How to prevent excessive logging of rhasspy?

Help
1

Hello,

rhasspy (debian package, not dockered) does a lot logging.
I found RHASSPY_LOG_LEVEL but it looks like I am not successful in setting the environment variable.

my systemd script is:

[Unit]
Description=Rhasspy Service
After=syslog.target network.target

[Service]
Environment="RHASSPY_LOG_LEVEL=error"
Type=simple
WorkingDirectory=/root/
User=root
Group=root
ExecStart=/bin/bash -c '/usr/bin/rhasspy --profile de 2>&1 | cat'
RestartSec=1
Restart=on-failure
#StandardOutput=syslog
#StandardError=syslog
SyslogIdentifier=rhasspy

[Install]
WantedBy=multi-user.target

this does not work.
can somebody help me on redicing DEBUG logs?

Thanks!
