MQTT Certificate

Using certificates will give you an additional layer of security for your MQTT communication.

To integrate MQTT with certificate into Home Assistant, add the following section to your configuration.yaml file:

# Example configuration.yaml entry
mqtt:
  certificate: /home/paulus/dev/addtrustexternalcaroot.crt
