I have a http post to execute.
When I go with my browser to: "http://192.168.10.232:8083/ZWaveAPI/Run/devices.instances.commandClasses.Set(255)" the command is executed correctly.
How do I write the same command to bttn.
Which argument format should I use and how do I type it in correctly.
the address seems to be a local IP address, accessible only within your home network.
When you press the bttn, the resulting HTTP request is made by bt.tn server located in the cloud (public Internet).
This means that you would need to have a public IP address or domain name for your server so that bt.tn server could send it the request.
When your server can receive requests from the public Internet, you should be fine with a HTTP GET request to the URL.
You could experiment with e.g. https://localtunnel.me
