How do I change the LED settings once a device is set up.

I originally set up the device with AQI and power/SD card LEDs on. I would now like to change it to AQI only.

I have tried the IP address config page and cannot see an option. I also cannot find on option while logged into the map with the device highlighted.

Do I need to reset and reregister or is there a way to toggle these settings easily?

Device is PAII-FLEX.

Thank you

Hi Con,

I had the same question for the same device and found the solution in a reply to an othervquestion.

———-  
The easiest way to check is to revisit the filled version of that form, which can be found on the “Registration Success” email. You’ll find a link at the bottom of that email called “Modify this registration” which will take you to a filled-out version of the registration form.

If your LED settings are set to “Full Color AQI Only,” then the sensor will only show the power and SD indicators on start-up, before turning them off. If you want them to stay on, you’ll need to set this option to “Power, SD Status, and Full Color AQI.”

I tried this and it works.

Success,

Edward

We also have a post about changing the LED settings here:

> With a new update to the PurpleAir registration page, you can access settings for the LEDs on your PurpleAir devices. You can turn the LEDs on and off and change their brightness with these settings. The LEDs that can appear on a PurpleAir sensor are the full-color AQI indicator, the red power indicator, and the green and blue SD card status indicators. The settings for the LEDs can be found in the Onboard LED Options section on the [registration page](https://www.purpleair.com/register). The following options in bold can be select…
