Sonoff Generic Modul + Tasmota 6.1.0a + 3 x DS18B20

Configuration
1

Hi

I’ve succesfully installed my Sonoff Generic Modul + Tasmota 6.1.0a and it works fine. But i’ve connected also 3 x ds18b20, and i don’t know how to run the temperature sensor in HA.

From my Sonoff Generic Modul i become this:

{"Time":"1970-01-01T00:42:20","DS18S20-1":{"Id":"000800C6726A","Temperature":24.8},"DS18B20-2":{"Id":"0118316109FF","Temperature":23.7},"DS18B20-3":{"Id":"02183149F1FF","Temperature":7.2},"TempUnit":"C"}

I have tested:

  -  platform: mqtt
     name: KS1
     icon: mdi:thermometer-lines
     state_topic: "tele/kuehlschrank/SENSOR"
     value_template: "{{ value_json['DS18S20-1']['Temperature'] }}"
     unit_of_measurement: "°C"

  -  platform: mqtt
     name: KS2
     icon: mdi:thermometer-lines
     state_topic: "tele/kuehlschrank/SENSOR"
     value_template: "{{ value_json['DS18S20-2']['Temperature'] }}"
     unit_of_measurement: "°C"

  -  platform: mqtt
     name: KS3
     icon: mdi:thermometer-lines
     state_topic: "tele/kuehlschrank/SENSOR"
     value_template: "{{ value_json['DS18S20-3']['Temperature'] }}"
     unit_of_measurement: "°C"

I’m accessing the values like this and it works perfectly fine:

- platform: mqtt
  name: KS1
  state_topic: 'tele/kuehlschrank/SENSOR'
  value_template: '{{ value_json.DS18S20-1.Temperature }}'
  unit_of_measurement: '°C'
  availability_topic: 'tele/kuehlschrank/LWT'
  payload_available: 'Online'
  payload_not_available: 'Offline'

Oh man.

The Problem was…

{"Time":"1970-01-01T00:42:20","DS18S20-1":{"Id":"000800C6726A","Temperature":24.8},"DS18B20-2":{"Id":"0118316109FF","Temperature":23.7},"DS18B20-3":{"Id":"02183149F1FF","Temperature":7.2},"TempUnit":"C"}

The first name ob “DS18S20-1” is with “S” the two other sensors is with “B” DS18B20-2. Shit.

Thanks!

Now is works fine with:

  -  platform: mqtt
     name: KS1
     icon: mdi:thermometer-lines
     state_topic: "tele/kuehlschrank/SENSOR"
     value_template: "{{ value_json['DS18S20-1']['Temperature'] }}"
     unit_of_measurement: "°C"

  -  platform: mqtt
     name: KS2
     icon: mdi:thermometer-lines
     state_topic: "tele/kuehlschrank/SENSOR"
     value_template: "{{ value_json['DS18B20-2']['Temperature'] }}"
     unit_of_measurement: "°C"

  -  platform: mqtt
     name: KS3
     icon: mdi:thermometer-lines
     state_topic: "tele/kuehlschrank/SENSOR"
     value_template: "{{ value_json['DS18B20-3']['Temperature'] }}"
     unit_of_measurement: "°C"
