        @Jimmy1502 I think the problem with the temperature is caused by the json path. The script outputs temperature_c and temperature_f but the json path causes the module to search for temperature only.

        The problem with the humidity may be caused by the interval you query the sponsor values. 10 seconds is very short for the dht sensor. Maybe you can try a bigger interval.

          @wishmaster270 I can see the temps now. I increased the UpdateInterval in both ValuesByNotification and CommandToNotification and made them different. But i still got the “0.00” for both temperature and humidity. But i dont think it should be the UpdateInterval. Cause when i tested the DHT22 with a Microcontroller i was able to get values every second.

            @Jimmy1502 As the reuseCount is set to 100 the wrong value need to be caused by the script sending them.
            It only sends 0.0 if a error occurs.

            You may remove the except block in the script and fire it very quickly on the shell to see what causes the error.

              Hi! Ive been busy so i couldnt work on it. I removed the except block with five “#” for each line to make it a comment. And i get the following error. The line 32 has a syntax error “invalid syntax”. It is the print function printing json.dumps(result))

                You will need to comment the try, too. Additionally the indention of the code needs to be changed.
                The file will be look like this then:

                #!/bin/python3
                #Install Dependencies:
                #  pip3 install adafruit-circuitpython-dht
                #  sudo apt-get install libgpiod2
                import time
                import board
                import adafruit_dht
                import json
                import sys
                
                gpio_nr = 4
                if len(sys.argv) > 1:
                    gpio_nr = int(sys.argv[1])
                
                
                # Initial the dht device, with data pin connected to:
                dhtDevice = adafruit_dht.DHT22(getattr(board, "D%d"%gpio_nr))
                
                result = {}
                result["temperature_c"] = dhtDevice.temperature
                result["humidity"] = dhtDevice.humidity
                result["temperature_f"] = (result["temperature_c"]*1.8) + 32
                result["error"] = False
                
                print(json.dumps(result))
