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
  certificate: /home/paulus/dev/addtrustexternalcaroot.crt

Configuration variables:

  • certificate (Optional): ‘auto’ or the certificate authority certificate file that is to be treated as trusted by this client. ‘auto’ uses the bundled certificates. If a file is specified the file should contain the root certificate of the certificate authority that signed your broker’s certificate, but may contain multiple certificates. Example: /home/user/identrust-root.pem
  • client_key (Optional): Client key, eg. /home/user/owntracks/cookie.key.
  • client_cert (Optional): Client certificate, eg. /home/user/owntracks/cookie.crt.
