Hey everyone, I’m trying to integrate a fingerprint reader into my Home Assistant setup, but I’m running into some issues. The fingerprint reader sends an MQTT message when a scan is successful, but my automation isn’t triggering as expected. Let me walk through what I’ve done so far and where I might be going wrong.
First, I set up the MQTT broker addon in Home Assistant and confirmed that the fingerprint reader is publishing messages to the correct topic. I can see the messages in the MQTT Explorer, so the communication seems to be working. However, when I try to create an automation that triggers on this MQTT message, nothing happens. I’m using the topic doorbell_hoftor/matchName and expecting a payload of Test, but it doesn’t seem to register.
I’m a bit confused about whether I need to create a sensor for this MQTT topic or if I can directly use the topic in my automation. I’ve tried both approaches, but neither has worked. Maybe I’m missing something in the configuration? I’ve also checked the logs, but there’s no indication of an error related to the MQTT message.
I would really appreciate any advice on how to troubleshoot this. Should I be using a different payload or topic structure? Is there a specific way to format the automation rule for MQTT messages? I’m determined to get this working, so any insights would be incredibly helpful!
Thanks in advance for your support!
