In the particulate matter configuration you can indicate in the API where you can send your own data.
The crazy thing is if I do this via Antagonist, the data does not arrive on my own web server, but if I test via another hosting, the data does arrive from the particulate matter.
The data is in Sensor data, but if it is on your own web server, this is easier.
Anatagonist himself says that it disabled TLS 1.1, could this be due to this ???
