I’m using the /sensors/id/history API call and I’ve noticed sometimes there are missing records. I’m not sure if this is a Purple AIr unit issue or a QAQC issue. Calling the “real time” API seems like overkill to be able to get the confidence indicator. For example platform id: 35359 I pull data from every 30 minutes. There are records missing, however there is no indication as to why that is. My guess is you’re doing some sort of QAQC and not storing them in database. It would really be useful to have some sort of indication on those records.
