Hi @ValeA
What the others in this thread have said is all correct. You can always access data locally over JSON. I feel it is also important to note that we do not intend to make sensor owners pay for the data from their own sensors. Until we get a more permanent solution in place, we will give sensor owners points to cover the cost of their own uses. If you are concerned about the points cost of obtaining the data from those volunteer house sensors, send an email to contact@purpleair.com and we will work with you.
For other ways to obtain sensor data, you can view our How to Obtain Sensor Data article.
