Renew certificates and notify on expiration

◀ Go back to main README

🛈 This script can not be used on its own but requires the base installation. See main README for details.


This script tries to download and renew certificates, then notifies about certificates that are still about to expire.

Sample notification

check-certificates notification

Requirements and installation

Just install the script:

$ScriptInstallUpdate check-certificates;


The expiry notifications just require notification settings for e-mail, matrix and/or telegram.

For automatic download and renewal of certificates you need configuration in global-config-overlay, these are the parameters:

  • CertRenewPass: an array of passphrases to try
  • CertRenewUrl: the url to download certificates from

Certificates on the web server should be named CN.pem (PEM format) or CN.p12 (PKCS#12 format).

Usage and invocation

Just run the script:

/ system script run check-certificates;

... or create a scheduler for periodic execution:

/ system scheduler add interval=1d name=check-certificates on-event="/ system script run check-certificates;" start-time=startup;

Alternatively running on startup may be desired:

/ system scheduler add name=check-certificates-startup on-event="/ system script run check-certificates;" start-time=startup;
