Laser Dust Sensor HM3301 with SkyWeather 2

I have my SkyWeather2 connected to the wireless outside and inside sensors and receive good data. I cannot however get data from the HM3301 to show up on the Blynk app "AQI". The sensor works fine and produces data when I run the testDustHM3301.py file. I do however get a message that the channel is already in use and continuing anyway. I have tried to run DustSensor.py and I get the following:

./SkyWeather2.JSON File exists

Traceback (most recent call last):

File "DustSensor.py", line 43, in <module>

During handling of the above exception, another exception occurred:
