Examples
Skipping automations right after a restart
You can use the uptime sensor in a condition to prevent an automation from running within the first few minutes after Home Assistant starts. This avoids false triggers while devices and integrations are still initializing.
conditions:
- condition: template
value_template: >
{{
now() - as_datetime(states('sensor.uptime'))
> timedelta(minutes=5)
}}
This condition passes only when Home Assistant has been running for more than 5 minutes.
