Hello, I was asked to help on a local community project to study Air Quality. I have two monitoring stations via PurpleAir. I can see data/ weekly graphs from both these stations. It appears that PurpleAir only holds/displays data for 1 week and it was suggested that ThingSpeak would [a]store historical data [b]able to "graph for longer periods of time". Is this true? Second question. It was only last week that I have heard of PurpleAir and ThingSpeak... is it possible for a Newbie to setup ThingSpeak to be able to visualize the AQI from my two monitors?
