Leds are suddenly never red after 1000ppm

Since some days ago, I’ve noticed that the color of the leds have changed.

previously, when over 1000ppm of co2, the leds turned red, but now even at 1200 they are just simply orange.

Any idea why and how to return it to the oldest color levels?

Hi @mrpaco!

The LEDs are orange from 1000 - 1500 ppm after which they turn red. You can find this info in Support > More About Monitors LEDs :

There was an update to correct the colors, as what was supposed to be Orange according to the page that Altair was actually appearing very Red, when that shouldn’t have happened until higher concentrations.

So yes it is different, but it should now match the intended behavior in the documentation

after like a year with the bug now I kinda want to be able to personalize them to match what I had previously lol

thanks for pointing it out.
