Filter specific log message

[mr_max]

Hi,
my log is getting spammed with messages like this:
Thu Sep 17 21:00:57 2020 daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED xx:32:xx:2a:xx:c7 static
Thu Sep 17 21:00:57 2020 daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED xx:32:xx:2a:xx:c7 off
Thu Sep 17 21:00:58 2020 daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED xx:32:xx:2a:xx:c7 static
Thu Sep 17 21:00:58 2020 daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED xx:32:xx:2a:xx:c7 off

Thu Sep 17 21:01:00 2020 daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED xx:32:xx:2a:xx:c7 static
Thu Sep 17 21:01:00 2020 daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED xx:32:xx:2a:xx:c7 off
Thu Sep 17 21:01:00 2020 daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED xx:32:xx:2a:xx:c7 static
Thu Sep 17 21:01:01 2020 daemon.notice hostapd: wlan0: STA-OPMODE-SMPS-MODE-CHANGED xx:32:xx:2a:xx:c7 off

I think it is caused by a phone with lineageos installed, but there is nothing I can do on the phone to stop this behaviour.

Is there any way to filter/disable this one specific message in the log, so it does not spam the log and overwrite everything else that is useful in the default syslog ring buffer?

Thanks

You should install rsyslog (https://openwrt.org/docs/guide-user/base-system/log.essentials#rsyslog_and_logzio): https://www.thegeekdiary.com/etc-rsyslog-conf-setup-a-filter-to-discard-or-redirect-messages/
