The cert_expiry sensor fetches information from a configured URL and displays the certificate expiry in days.

Configuration

There are 2 options in configuring the cert_expiry sensor:

• Via the Home Assistant user interface where it will let you enter a name, host and port for the certificate to check.
• Via the Home Assistant configuration.yaml file.

# Example configuration.yaml entry
sensor:
  - platform: cert_expiry
    host: home-assistant.io

{% configuration %} host: description: The host FQDN (or IP) to retrieve certificate from. required: true type: string port: description: The port number where the server is running. required: false default: 443 type: integer name: description: The friendly name for the certificate. required: false default: SSL Certificate Expiry type: string {% endconfiguration %}

Make sure that the URL exactly matches your endpoint or resource.
