Mqtt sensor no value?

Installation Home Assistant OS

I use a mqtt sensor for measurements.
The mqtt works, i can read the value if i ssh to the raspberry
But hassio gives me a empty value??
What is wrong here?

  - platform: mqtt
    name: "LastUpdate"
    state_topic: "DSMR-WS/DateTime"
    unit_of_measurement: ""
    value_template: "{{ value_json.DateTime }}"
   

  - platform: mqtt
    name: "Energy Delivered"
    state_topic: "DSMR-WS/EnergyDel"    
    unit_of_measurement: "kWh"
    value_template: "{{ value_json.EnergyDel }}"     
    
  - platform: mqtt
    name: "Energy Returned"
    state_topic: "DSMR-WS/EnergyRet" 
    unit_of_measurement: "kWh"
    value_template: "{{ value_json.EnergyRet }}"
    
  - platform: mqtt
    name: "Power Delivered"
    state_topic: "DSMR-WS/PowerDel" 
    unit_of_measurement: "kW"
    value_template: "{{ value_PowerDel }}"

Are they all empty, or only the last where the value_template looks wrong?
