Setup and manage a [Let's Encrypt](https://letsencrypt.org/) certificate. This will create a certificate on the first run and renew it if the certificate is expiring in the next 30 days.
```json
{
"email": "example@example.com",
"domains": ["example.com", "mqtt.example.com", "hass.example.com"]
}
```
Configuration variables:
- **email** (*Required*): Your email address for registration on Let's Encrypt.
- **domains** (*Required*): A list of domains to create/renew the certificate.
## {% linkable_title Home Assistant configuration %}
Use the following configuration in Home Assistant to use the generated certificate:
```yaml
http:
ssl_certificate: /ssl/fullchain.pem
ssl_key: /ssl/privkey.pem
```
