We are actually already taking ten or twenty measurements in a row and average them before sending to the server.
Though, I am not sure if we transmit decimal numbers. @Samuel_AirGradient can you check this? If not, that might become a piece of the solution.

Home Assitant was only taking one, so I suspect some of the confusion when users are comparing were a direct result from thatâŚwhere the cloud actually had better data. Iâm happy the cloud app does have this logic! 
The decimal places in the Cloud app calculation would definitely affect users with consistently low PM values. Mathâs fun xD
I ran the above script locally here
root@prod[~]# for i in {1..300}; do echo "$(date '+%Y-%m-%d %H:%M:%S') pm02Compensated: $(curl -s http://10.69.10.92/measures/current | jq -r '.pm02Compensated')"; sleep 3; done
