Locally Controlling LED Brightness on PurpleAir Zen

I’ve been using the PurpleAir Zen air quality monitor, and I’m wondering if there’s a way to control the LED brightness locally. Specifically, I’d like to automate the brightness based on the time of day so it no longer lights up the entire side of my house at night with the color. Currently, adjusting the brightness involves re-registering the device via a form, which can be a bit cumbersome and seems like overkill.

Has anyone been able to figure out how to send a command locally to do this.
Thank you in advance for your help!


Hi @bbech

I don’t believe there is currently a way to control a device’s brightness with some sort of local command. However, the Zen and Touch models have double-tap to change brightness capabilities.

I requested this feature almost a year ago now. Schedule LED brightness
