Possible to get a node-red example ?

[Cliff-R-K]

I have been searching but have not found any instructions of how to get double-take to work in node-red. I am using home-assistant but am using node-red for all my automations. I have been fiddeling around but can not figure out how to trigger anythoing on sensor.double_take_. Is it possible to get any examples of what needs to be configured in double take and some simple flows where you trigger something when a known person enters in a cameras view ?

Hi. Here is one for an HA sensor:

  - platform: mqtt
    name: name
    icon: mdi:account
    state_topic: 'double-take/matches/name'
    json_attributes_topic: 'double-take/matches/name'
    value_template: '{{ value_json.camera }}'
    availability_topic: 'double-take/available'

Have you tried using automations instead of node-red? I used to use node-red exclusively just like you to make debugging easier but made the switch after automation tracing was added.

I just saw that you are asking for node-red instructions. You will want to use an mqtt in node listening for this topic double-take/matches/[NAME]

@ozett what is that last function your using in node-red ? image ?!?!? Can you help? Thanks in advance

[ozett]

@nmsoares . i dont understand the question for the last function. may you could ask with more context. what do you want to achieve?

[nmsoares]

@ozett the node-red example you've posted has in the end a "image" node. What is the name of the node...I seam to not have it on my system. Thanks in advance for your time and support.

@nmsoares Here's a node that renders images - https://flows.nodered.org/node/node-red-contrib-image-output

Not sure if it's what ozett is using though.

[ozett]

yes, its node-red-contrib-image-output
