Lovelace card does not display any values from MQTT client

Configuration
1

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

I created lovelace sensor cards:

gauge
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?

Based on the structure of the received JSON payload, the current value should be extracted like this:

    value_template: "{{ value_json.SSerialReceived.I1 }}"

Here’s the proof:
