MQTT HomeAssitant Door opened

Christian_SU · March 14, 2025, 1:06pm

Hello,
I’ve had the Nuki 3.0 Pro with a keypad for a year now and I’m very happy with it. I integrated it into Home Assistant from the very beginning. Now I’ve integrated MQTT (Mosquito), which I’m completely new to.

I want the hallway light to turn on automatically when the door is opened from the outside and it’s dark. A corresponding automation in Home Assistant would be very simple. I’m currently still struggling with the MQTT information. When I look at the log, I find the following under “nuki/23232/state”:

I think I found the following:
Payload: 7 (Fingerprint)
Payload: 5 Door was opened
Payload: 3 Door was closed

My question now is: How can I query this in HA and use it in my automation?

The sensors displayed in the HA aren’t helping me. Or am I missing something?

A little help would be very welcome.

Best regards,
Christian

Hi Christian,

State 7 is “Unlatching” not “Fingerprint”.
For a definition of all the states please refer to our MQTT API specification.

If the “Opened” state is sufficient for you, you may create an automation like this:

Hi Marc,
thanks for your help! The “opened” state is not available, only “opening”. But this would be fine for me.

I’ve just wrote the automation and now i’m waiting for the night to test it. Here is the automation in HA:

In German it is called “… geöffnet ist”:
