Gosh...I do not know what to say, you are genius! Many thanks for you help, I can now read the temperature every X seconds

Sure, here is my script:

#!/usr/bin/php
<?php
$json_string = file_get_contents ("https://api.example.com");
$parsed_json = json_decode($json_string, true);
$parsed_json = $parsed_json['result'];
echo "Temperature ".$parsed_json."C"."\n";
?>

Yes, the script is on the same system in ../domoticz ...

Hi there! Sorry to intervene but I have got the same question and I cannot get my head around it.

I have got a php script which reads an JSON API and get a string as follows: Temperature 30.1C

Now I want to display this result in the dashboard and I cannot understand how to do it. Happy to run ...
