Security Note
We strongly advise to always use TCP with TLS to make sure your data travels encrypted, avoiding the exposure of your API token and/or sensor data to third parties.

Note: To avoid future inconveniences, we advise to use both certificates in your device's auth routines. While the second is the current valid certificate, we will use the first after 2021.
