using dzvents to listen on a port

[heggink]

Can that be done? My Nuki locks allow me to install a hook whereby any state change is reported in a nuki json format to any ip:port I want so every time a lock is changed, it's state change is reported.
I'd like to capture these changes in dzvents instead of in my current bash script so I need some way to get dzvents to listen for json messages on a specific port on my raspberry pi (where domoticz also runs). I struggle to understand how the asynchronous http mechanism supports that...

Any help greatly appreciated.

Have a look at the dzvents manual, under the topic http response.

that's what I tried but I fail to see how I can listen on a port without issuing a request first...

If your nuki (bridge) can send something like /json.htm?type=command&param=updateuservariable&vname=NAME&vtype=TYPE&vvalue=VALUE
to domoticzIP:domoticzPORT then dzVents can be used because domoticz will then trigger an event.
As far as I understand, the current dzVents version only reacts to events triggered by domoticz.

That won't work if it only can send a json string. You could use a small php page to decode the json.

You could create a python plugin that listens for JSON.

Under plugins/examples there is one called "HTTP Listener" which shows how to listen on an ip & port. If you set the connection's protocol to JSON rather than HTTP it will return JSON messages in dictionaries (and/or lists depending on the JSON) in the onMessage function when your Nuki sends a message.

EDIT: Just looked Nuki up, looks interesting. If you need help writing a plugin let me know.

Help? YES PLEASE. My python skills are really appalling (I'm just an old C programmer who knew when to quit ).
These nuki devices are really great. I have had them for quite a while. I did mod them to replace the batteries with a power adapter as they don't like being polled (drains the batteries).
I'll take a look at the python plugin and put some thoughts on paper.
Many thanks for the offer!
