Security Note
We strongly advise to use HTTPs to make sure your data travels encrypted, avoiding the exposure of your API token and/or sensor data.

Connected Sensors supports SSL v1.1, TLS v1.2 and v1.3. You can download our root certificates in different formats:

PEM file: A certificate chain with two root certificates from our certificate authorities (CAs).
DER file: Same as the PEM file, with an alternative encoding.
CRT file: Same as the PEM file, with a different extension. Often referred to as .crt, .cert or .cer.

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.
