O3 and NO2 seen once

1

I had to restart my sensor because of a broken WIFI connection. After restart I saw O3 and NO2 measurements for the first time. After an hour these two measurements are not seen anymore.
Questions:
Are these measurements representative?
I suppose at least indicative?
What to do to see these always.

Thanks in beyond for reaction.

Our devices can’t measure O3 or NO2. So this looks like a failure of the app. But Air Matters ist a completely different project and/or app. So maybe you don’t have a device build following our instructions?

Hi Ricki,
Thanks for your reaction.
The sensor is build exactly cfrm the instructions. Then I suppose its really an app failure.
