Is there a way to use this in automations in Home Assistant? #4

Is there a way for Home Assistant to know this process has been executed and what plates have been detected to use this information in automations? (i.e. notify you when a known/unkown car has been detected)

ljmerza commented 1 year ago

in v1.3.0 I added a return topic config return_topic: plate_recognizer that returns a mqtt message with plate data

heisenberg2980 commented 1 year ago

@ljmerza you are a star! testing it now

heisenberg2980 commented 1 year ago

The process generates this error and restarts when trying to write a message to the return topic:

TypeError: payload must be a string, bytearray, int, float or None.

heisenberg2980 commented 1 year ago

Error has been fixed in 1.3.2, thanks @ljmerza

Note: For anyone coming here with a similar question, Plate Recognizer also has a Webhooks option (included in the free account) that can be setup to call Home Assistant every time a call to the recognition API is made, but that requires Home Assistant to be accessible from the internet.

Alright, this is the first time for me, I set this ip, did the config and MQTT within Frigate and the frigate_plate_rec.

MQTT has been setup within Home Assistant, it's connected with Frigate and the plate_rec. But where can I find this? The notification for when a known/unkown car has been detected. This is for my garage, when it reconize the license plate the garagedoor opens. Where can I add the license plate btw so it knows the car is on the driveway?

The docs mention an mqtt event that will be sent when a license plate is detected. You can use that to create an entity from the mqtt sensor entity

I'm sorry, how do we create the entity? Hope you can help me.

It does work by checking the license.

Maybe @heisenberg2980 want to share his MQTT configuration? It's important for me that if it detects my license plate the garagedoor opens.

@BliXem1 I am using the webhook option I mentioned here: https://github.com/ljmerza/frigate_plate_recognizer/issues/4#issuecomment-1714566767 which is a bit more complex, but getting the value from MQTT shouldn´t be difficult. If this is the first time you are working with MQTT, I would recommend you to install the Windows app "MQTT Explorer" as a first step, so you can see if the messages from plate recognizer are reaching your MQTT broker
