Hello!

I need to parse a JSON array like that:

[
{"Test":"Output "},{"Test2":"Output2"}
]

I am using the "HTTP/XML Rest-Sensor" but it shows me the error "Data at the root level is invalid. Line 1, position1."

I read that its because of the "[" at the beginng. Can somebody tell me how I can fix this?

Hi Manuel,

Thank you for the KB-Post. Can you please use the new Rest Custom Sensor for a test? Does it throw the same error?

best regards.

Hello, thanks for your help and I tried the "Rest Custom Sensor". Unfortunately it doesn't work for me. Now I get following error: "can not query endpoint can not load entdpoint http://0.0.0.0https://admin......."

Default settings in the "Rest Custom Sensor" with Basic authentication and "channelDiscovery" as REST Configuration.

Best Regards, Manuel

Hi there,

As the error message indicates, the requested URL can't work. For example you have the following URL:
http://my-server/json/api/api.php

Then please enter the first part, the domain/hostname into the connection settings of the device:

  • IPv4 Address/DNS Name: my-server
    Afterwards enter the last part, the URL, into the URL field of the sensor:
  • REST Query: /json/api/api.php

    Best regards.

Hi there!

It's working now, thanks!

Is it possible to add a hyperlink to the channel names that leads to another site? Atm I just see state number, ID etc. but nothing informative.

Best Regards

Hi there,

Unfortunately, that is not possible. You can however add the URL in the device settings as the service url of the device.

Best regards.
