parse a string of sensor values

[Jony26]

Good day! Help me understand how to parse a string of sensor values
{
"DTime": "08-01-2023 12:31",
"Time_rab": 211.12,
"WiFi": -58,
"htu21_T": -3.2,
"htu21_H": 47,
"mqtt": "доступен",
"value_vorota": "close",
"sens_down": "Выкл",
"sens_up": "Вкл",
"time_val": 10,
"ir": "On",
"time_val_rab": 10,
"ds3231_T": 0.5
}
earlier in the code I used the formula "value_template": "{{ value_json.Time_rab }}" and got the desired value. How to do it by means of ArduinoHA?
