Serial sensor doesn't work anymore

Configuration
1

Hi,

I use the serial sensor input to read mine Arduino one in JSON style.
But there is noting changed and it doesn’t work anymore. als not after reboot from hassio or the Arduino or reconnect the USB.
Can anyone give me a reason why und maybe a solution?

the log say’s hassio find the Arduino one.
21-05-29 20:46:41 INFO (MainThread) [supervisor.hardware.monitor] Detecting HardwareAction.ADD usb hardware /dev/bus/usb/001/009 21-05-29 20:46:41 INFO (MainThread) [supervisor.hardware.monitor] Detecting HardwareAction.ADD serial hardware /dev/ttyACM0 - /dev/serial/by-id/usb-Arduino__www.arduino.cc__Arduino_Uno_756363131373510150E0-if00

I can read the JSON file with de monitor from the Arduino software:
22:46:32.427 -> {"temperatuur":15.00,"lichtsterkte":4,"regensensor":502,"windsnelheid":0.00}

and de configuration is:

  - platform: serial
    serial_port: /dev/ttyACM0
    baudrate: 9600

  - platform: template
    sensors:
      temperature_sensor:
        friendly_name: "Temperatuur"
        unit_of_measurement: "°C"
        value_template: "{{ state_attr('sensor.serial_sensor', 'temperatuur') }}"
      light_sensor:
        friendly_name: "lichtsensor"
        unit_of_measurement: "Ohm"
        value_template: "{{ state_attr('sensor.serial_sensor', 'lichtsterkte') }}"
      rain_sensor:
        friendly_name: "regen"
        unit_of_measurement: "regen"
        value_template: "{{ state_attr('sensor.serial_sensor', 'regensensor') }}"
      wind_sensor:
        friendly_name: "windsensor"
        unit_of_measurement: "m/s"
        value_template: "{{ state_attr('sensor.serial_sensor', 'windsnelheid') }}"

Oke I fixe it with this: Using serial sensor for reading JSON output from Arduino?

You need to put this: Serial.println('\n'); on the end of you’re Arduino sketch.
I wondering why tis first worked but very happy that it worked yet.

Hi,
I thought that I fixed mine problem (see the link below).

But it is not true.
Wenn I plug the USB cable in de data is refreshed but does not refresh any more.
When I take the cable out and in again the data is refreshed.
Why does the serial sensor refresh anymore?
