Hi @savagebill00, our systems show the MAC address for your indoor device starts with 48. If you’re having trouble re-registering with this MAC address, then there might be an issue with the emails you are using. Please ensure that you’re using the same emails previously registered to the device. You can find these by looking for a registration confirmation email previously sent by us.
If you would like assistance in changing the emails for your device, please send an email to contact@purpleair.com.
We’re also able to see your sensor is currently connected and reporting to the map. If you’re still unable to see it, please ensure that the map setting labeled “Show Inside” is checked. This option toggles whether indoor sensors appear on the map. You can find more details in our Map Startup Guide.
