So that preset dimmer is for my Kasa smart dimmers, since they are WiFi, they rely on polling to detect physical presses. Due to this, I preset the brightness per mode, so that the first press in that mode is already this right brightness and does not have to wait for the polling to detect a change and then change the brightness accordingly.
This is using the custom community driver for Kasa Integration. It was a feature I adapted and requested from the dev.
