Default dim setting on Levitron wall switch

Hi everyone,

I resurrected my Smartthings hub after not using it for a year. I recently connected it because I need to turn on a stairway light to our newly remodeled basement.

I have a Levitron dimmer switch installed and an Iris motion sensor. Right now the automation works.

My issue is that I would like it to turn on the light on at 35% and can’t figure out how to do that. I have it turning on using the smart lighting app.

Also is there a way to have it turn off after 30 second? The minimum currently is 1 minute.

Thanks
