Hi All,

I recently got the Homewizard P1 Meter.
Their documentation describes how to request a new user token, but i can not get it to work.

I have my http post setup as:

What am i doing wrong?

Have you physically pressed the button on the device

  1. The user opens your app which initiates a network scan, discovering a device, such as a P1 Meter.
  2. After selecting the P1 Meter, the app sends a POST /api/user request with the necessary parameters
  3. The device responds with a 403 Forbidden status, indicating that the user must physically press the button on the device to continue.

Even if i press the button, I still get the same error.

All I can think is the new_user section of the name may need to be a username.

looking again the name needs to be in the payload not the header

From the node-red system can you ping 192.168.86.32 ?

On the website the curl example is

curl https://<IP ADDRESS>/api/user --insecure \ 
-X POST \
-H "Content-Type: application/json" \  
-H "X-Api-Version: 2" \  -d '{"name": "local/new_user"}'

it has the --insecure flag which is to connect to server that has self signed certificates ?
In Node-red you can try to set from your Inject node msg.rejectUnauthorized to false
