Just hooked up my sensor a few days ago and it has been on map until this morning.
Light is red. Unplugged it and plugged it back in but it still is not reporting.

Hello,
Glad to have you in the community! Happy to help take a look at your sensor. If you could share the device ID with us at [contact@purpleair.com](mailto:contact@purpleair.com), or message it to me privately on this forum, we can take a look at it on our end.
You can find this ID labeled on the sensor physically, or in the shipping or registration confirmation emails you may have received for it.
Thank you!

_Hi,_
_Thank you for your response._
_My device ID number is: xx:xx:xx:xx:xx:xx_
_It has been working intermittently ever since I reinstalled it. My place is seasonal so it was stored inside (unplugged) from November until July._
_Today it’s on the map without my touching it these last few days!_
_Any suggestions are welcome._
_Thank you!_

Hello,
Thanks for sending that over! Just so you know, I edited your device ID for your privacy. I was able to pull up your sensor.
I took a look at your sensor’s connection since it was recently reinstalled, and it looks like it has been online with a stable connection for 11 days. It’s possible that you weren’t able to see your sensor due to a brief period where we had some downtime due to high traffic. We’ve resolved that issue, so you should be good going forward.
Let us know if you have any further issues. Thank you!

_Thank you!_
_Let’s hope things stay GREEN!_
