Is your Home Assistant setup misbehaving? You’ve set up all your smart home automations—lights, thermostats, door sensors—but suddenly, nothing works. If you’re reading this, it’s likely that your Home Assistant automations are not running when they should. Don’t panic—this guide will show you how to get them back in action quickly. In this detailed post, we’ll walk through the best fixes, checks, and tweaks to make everything run smoothly again. Welcome to your ultimate troubleshooting guide: Home Assistant Automations Not Running — Fix Now — Best Tips to Get It Working Again.
Quick summary: This guide covers causes and solutions for non-working Home Assistant automations. From YAML mistakes to trigger issues and device errors, we’ll help you identify what’s wrong, fix it, and optimize your automations for reliable performance.
1. Check If Automations Are Enabled
Before diving into advanced fixes, start simple. Many users discover their automations were accidentally turned off. Home Assistant allows you to toggle automations manually, and sometimes updates or experiments disable them.
Home Assistant Automations Not Running — Fix Now — Best Tips to Get It Working Again Step 1
Go to Settings → Automations & Scenes and check each automation’s status. If you see an automation grayed out or marked “off”, toggle it to “on”. Once enabled, test its trigger to verify it’s functioning again. It’s a basic step but often the most overlooked.
- Navigate to Configuration → Automations.
- Confirm each automation shows “Enabled”.
- Click the “Run Actions” button to test if the automation executes manually.
If automation runs manually but not on its trigger, don’t worry—we’ll solve that next.
2. Verify Triggers and Conditions
A common reason for automations not firing comes down to trigger or condition logic. Home Assistant supports time, state, numeric state, event, and template triggers, but even one wrong value can sabotage your setup.
Check Trigger Configurations
Inspect your YAML or UI editor. Look for typos or invalid entity IDs. If an entity ID has changed (for example, a renamed light or motion sensor), the automation won’t detect the event. Re-select the right entity and test again.
- Open the automation editor.
- Click on “Triggers” → ensure the entity exists and is spelled correctly.
- Review any conditions—they must all evaluate to “True” for an automation to run.
You can also check the Automation Trace feature for an execution history that explains whether a condition blocked the flow.
3. Update Home Assistant and Components
Outdated versions can break automations due to deprecated YAML syntax or integration updates. Make sure everything is up to date.
Why Updating Solves So Many Automation Problems
The Home Assistant community releases frequent updates that fix known bugs. To prevent compatibility issues:
- Backup your existing configuration first.
- Go to Settings → System → Updates and apply available updates.
- After updating, restart Home Assistant completely to reload automation scripts.

4. Inspect YAML Syntax and Automation Errors
YAML formatting errors can silently break automations. Even a single misplaced space or colon can keep the file from loading.
Use Check Configuration Tool
Navigate to Developer Tools → YAML → Check Configuration. This tool inspects your setup for syntax issues before you restart Home Assistant. If it reports an error, note the file and line number, then fix formatting problems with a YAML validator.
You can also open the Logbook or Home Assistant core logs under Settings → System → Logs to see if an automation failed to load at startup. The error messages often pinpoint what needs correction.
5. Review Time Zone and Date Settings
Time-based automations rely on your system clock. If your local time or time zone is misconfigured, automations that should run at 8:00 p.m. might instead trigger at odd hours—or not at all.
Fixing Time-Based Issues
- Go to Configuration → General → Time Zone.
- Ensure your region and offset are correctly set.
- Restart Home Assistant to make sure new time settings are active.
Accurate scheduling depends on synchronized time data. If you sync Home Assistant with your router or an NTP server, verify that the sync process is working correctly.
6. Clear Cache and Restart Home Assistant
Sometimes a fresh restart resets stalled services or integrations that block automations. Cached data can also conflict with new configurations.
Simple Restart Procedure
- Click your profile icon → “Restart Home Assistant.”
- Optionally, clear browser cache if you use the web front end frequently.
- After reboot, retest problematic automations using the “Run Actions” button.
If things start working again afterwards, it means a cached process or transient memory issue was the cause.
7. Check Dependencies and Integrations
Some automations depend on integrations—like MQTT, Google Home, or Z-Wave—that sometimes fail to load or reconnect. When that happens, triggers won’t fire because the related devices appear “Unavailable.”
Testing Integration Health
- Head to Settings → Devices & Services.
- Check for integrations showing “Error” or “Unavailable.”
- Reload or reauthenticate the integration if prompted.
When integrations depend on external services (like weather APIs), make sure your internet connection is stable and credentials are valid. If you suspect a broken integration, remove it temporarily, restart, and add it back.
8. Bonus Optimization Tips
Once your Home Assistant automations not running issue is fixed, take time to strengthen your setup:
- Use Automation Traces to monitor performance over time.
- Document automations clearly so you understand dependencies later.
- Group related automations using scripts to simplify debugging.
- Review logs regularly for warnings—prevention is easier than diagnosis.

Final Thoughts
By following these steps, you can quickly identify whether the issue lies in your configuration, triggers, conditions, or integrations. Most “Home Assistant automations not running” problems turn out to be small oversights that can be fixed in minutes. With the tips above, your system will be back managing schedules, lights, security, and more—just as it should.

FAQ 1: Why do my automations only run manually but not automatically?
This usually means the trigger isn’t firing correctly. Check the automation’s trigger and condition logic. Sometimes the entity is renamed or no longer available. Running it manually proves the actions are fine—the issue lies in the trigger setup.
FAQ 2: Do I need to restart Home Assistant after editing automations?
Yes, if you edited YAML files directly. Changes made in the UI apply instantly, but YAML changes require a restart to load. Always use the “Check Configuration” tool before restarting to prevent errors.
FAQ 3: How do I trace why an automation failed?
Use the Automation Trace feature to view real-time execution paths. It shows whether conditions blocked the automation, whether triggers activated, and which actions executed. This is your best friend for detailed troubleshooting of any automation problem.
