Scrape 123solar

Please format your code properly by surrounding it with three backticks. See item 11.

If that’s real JSON coming from the PHP resource, you could try a REST sensor:

sensor:
  - platform: rest
    resource: http://192.168.1.210/123solar/programs/programmultilive.php
    name: Produzione fotovoltaico
    value_template: '{{ value_json[0]["GPTOT"] }}'
    unit_of_measurement: "W"
    scan_interval: 60
