My forray into Home Assistant blueprints (and more?).
This blueprint depends on the Certificate Expiry integration.
The blueprint will return an array of dictionaries, which can be referenced using {{items}}. This way you can gain greater control over how the output should be handled.
An example of the returned data:
[
{
"host": "portainer.example.com",
"port": "9443",
"relative_time": "9 days",
"entity_id": "sensor.cert_expiry_timestamp_portainer_example_com_9443",
"state": "2023-02-24T20:24:44+00:00"
},
{
"host": "proxmox.example.com",
"port": "8006",
"relative_time": "1 day",
"entity_id": "sensor.cert_expiry_timestamp_proxmox_example_com_8006",
"state": "2023-02-16T23:06:53+00:00"
},
{
"host": "www.example.com",
"port": 443,
"relative_time": "9 days",
"entity_id": "sensor.cert_expiry_timestamp_www_example_com",
"state": "2023-02-24T20:19:17+00:00"
}
