Troubleshooting
There are several things you can check on your BlueSky monitor if it does not turn on.
Check to make sure the power supply is in good working condition. If it is not, a replacement can be ordered on the TSI website (North America-style power supply, European-style power supply, UK-style power supply).
The LED light may have failed. Check to see if the device is connected to TSI Link™ Solutions or if it is emitting its Wi-Fi signal when in setup mode. If the device is connected to TSI Link Solutions and reporting its data, then the green LED light might not be working. If this is the case, the device can still be used.
Check the green LED light on the bottom of the BlueSky Air Quality Monitor. You can determine what might be happening based on its flashing pattern. The table below explains the meanings of different LED flash patterns.

If this continue for more than two (2) minutes, check to make sure your SSID and password are correct
If data is not saving to the SD card, the card may be corrupted or has failed. Confirm the SD card is working properly by inserting it into a computer to make sure you can access the files. If you determine the card is not working properly or has failed, insert a new card into the BlueSky monitor. Your BlueSky monitor can accommodate up to a 32 GB SD card. It comes with a 16 GB card already installed.
There are several things you can check on your BlueSky Air Quality Monitor to find out if it is working.
Confirm the device has power by looking at the green LED light on the bottom of the BlueSky monitor. If the green LED is not flashing, then the device may not have power.
Check the green LED light on the bottom of the device. Use the following chart to determine if there is an issue with the WiFi or TSI Link Solutions connection:
Reset the BlueSky monitor by unplugging it and plugging it back in to the power supply. Additionally, you can check other air quality monitors in the area to see if those devices are reading similarly – if so, then the readings are probably accurate. If the readings are different by a large amount, the BlueSky monitor PM sensor may have failed – a new PM sensor would need to be purchased. Also, check to make sure a calibration factor did not get accidentally entered into TSI Link Solutions, causing the data to be skewed.
If your PM sensor data doesn’t appear, the sensor may be reaching its end-of-life and needs to be replaced. You can order a replacement sensor from from the TSI website (single sensor, pack of 5 sensors) and install it yourself.

If you believe that, after changing the calibration factor, the data is not correct, it is best to spot check by observing, recalculating, and resetting the calibration. For example, change the calibration factor back to the default 1.0 for a short period of time. Then enter the custom calibration factor again and observe the data.
First, confirm you plugged the sensor in correctly. Disconnect the power and trying unplugging and plugging the sensor back in. If that does not work, you may have received a faulty sensor. If you have another working sensor available, install that sensor instead to see if you can get the monitor to work. If you have another BlueSky monitor available that is working properly, try swapping sensors between the two to determine if the issue is with the sensor or with something else within the original BlueSky monitor.
Once the new sensor has been plugged into your BlueSky Air Quality Monitor, the factory calibration will upload to TSI Link Solutions. You can use the data on the cloud to verify the sensor was calibrated.
If you can access the device, try to reset your BlueSky Air Quality Monitor with a power cycle. To complete a power cycle, unplug the power supply, wait a few minutes, and plug it back in. Then check the PM sensor status in TSI Link Solutions (see FAQ “1. How do I know my BlueSky Air Quality Monitor is working fine?” on the Error Diagnosis FAQ Page). If your PM sensor data displays a status warning about the sensor reaching its end-of-life, the PM sensor will need to be replaced (see FAQ “5. Where do I order new BlueSky Air Quality Monitor sensors?" on the Error Diagnosis FAQ Page).
If all of the PM channels have not changed for a long time, the PM sensor may have failed. Try to reset your BlueSky Air Quality Monitor with a power cycle. To complete a power cycle, unplug the power supply, wait a few minutes, and plug it back in. This may reset the PM sensor and get it working again. The PM channels should not all be reading the same values over time.
If you are able to install the sensor, yes it will work. However, you will get a warning on TSI Link Solutions stating it is not a recognized serial number. Additionally it may read different when compared to your BlueSky devices, because the sensor was not calibrated by TSI. It is recommended that all replacement sensors are purchased from TSI for your BlueSky monitor.
