How to Fix Frigate MQTT Events Not Publishing
- Broker auth failure
- Topic config mismatch
- Network route to broker broken
Problem Description
When your Frigate Frigate MQTT Pipeline isn't working as expected, it usually traces back to one of a small number of causes — this guide covers them in order, starting with the most likely.
Symptoms
- No MQTT events
- Automation not triggered
- Frigate detections still visible
Recognize these? Here's what usually causes it.
Common Causes
- Broker auth failure
- Topic config mismatch
- Network route to broker broken
Most fixes happen in the first 3 steps.
Do not debug downstream automations before confirming upstream publish flow.
Tools & Requirements
Step-by-Step Solution
Check broker authentication
Verify user/pass and ACL allow publish on event topics.
Inspect topic names
Confirm automations subscribe to actual Frigate topic paths.
Run publish test
Validate broker path from Frigate host and monitor events live.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
MQTT topic naming consistency prevents silent automation breakages.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
