Lovelace card does not display any values from MQTT client

Hi Friends!

I am trying to display readins from current sensors in HA.

Data are sent from from ESP8266 with Tasmota over MQTT to HA.

I can read the data in HA using MQTT listening:

{
    "SSerialReceived": {

        "I1": 0.07,
        "I2": 0.02,
        "I3": 0.01,
        "I4": 0.03
    }
}

Auto discovery did not wor so I created sensor entities manualy:

sensor:
  - platform: mqtt
    name: I1
    unique_id: "I1"
    state_topic: "tryskac/zatizeni/RESULT"
    unit_of_measurement: 'Amp' 
    value_template: "{{ value_json.I1 }}"
  - platform: mqtt
    name: I2
    unique_id: "I2"
    state_topic: "tryskac/zatizeni/RESULT"
    unit_of_measurement: 'Amp' 
    value_template: "{{ value_json.I2 }}"
  - platform: mqtt
    name: I3
    unique_id: "I3"
    state_topic: "tryskac/zatizeni/RESULT"
    unit_of_measurement: 'Amp' 
    value_template: "{{ value_json.I3 }}"
  - platform: mqtt
    name: I4
    unique_id: "I4"
    state_topic: "tryskac/zatizeni/RESULT"
    unit_of_measurement: 'Amp' 
    value_template: "{{ value_json.I4 }}"

Sensor entities have been created

entities1170×343 5.91 KB

I created lovelace sensor cards:

gauge1450×548 15.7 KB

But no any values are displayed.

I am playing with it couple of days and became desperate.

Any idea what could be wrong?
