Will the indoor monitor change color if very poor humidity only.
My AirThings indoor shows good AQI with poor humidity. My purpleair indoor monitor is red despite good outdoor AQI.
Hi Romel,
The PurpleAir Touch will only change colors according to the US EPA PM2.5 AQI. No other type of data, including humidity, will affect the sensor's lights. If the device continues to report poor air quality when you think it is not, we would be happy to help you troubleshoot. To start troubleshooting, please send an email to contact@purpleair.com.
Can't be sure if it is my monitor
Hi Gerald,
The position of sensors on the map is set during the registration process. If you are unsure where you monitor is, please send an email to contact@purpleair.com and we can assist!
Will advise once I have had time to hook it up thanks
I only purchased it about two weeks ago but so far very happy with it. Also, unlike with purely commercial manufacturers there is great community to get answers and learn and someone will pick up the phone when support is needed.
I like the idiot color indicator's that gives a rough idea of the air quality. I can always look at the web portal for en exact AQI level. USB cord is short, so I purchased a USB extension (might be a good option to have available on website). WIFI signal weak, I had to move several times to get a decent signal strength (my other devices have no issues). Lastly, my device shows grayed out a lot. I have to set conversion to “no” so that it shows zero instead of being grayed out. The annotation says check WIFI, it’s good. After reading on the community board, I believe it’s a PurpleAir issue that needs to be fixed, looks like it’s been lingering for awhile.
I’m still glad, I purchased it. Customer support has been first rate.
Hi Duane,
I know we've corresponded in other areas. But I want to let others know here that the offline sensor is a bug affecting the US EPA conversion on our map. It will be fixed in the next map version.
