MQTT Sonoff/Tasmota TH10 Temp sensor readings Noob

Configuration
1

I’ve set up my first Sonoff TH10 flashed with Tasmota, switch working fine but using the Sonoff DS18B20 temp sensor HA appears to be treating the temp sensor value as a text not a numeric value, it appears on the front page icon as ’ 28.4’ (single quote marks before and after value) and no values are plotted on the history values graph when double clicked.

this is the MQTT from the Tasmota console

MQT: tele/fishtank_temp/SENSOR = {"Time":"2018-02-18T06:56:46","DS18B20":{"Temperature":28.4},"TempUnit":"C"}

see below for my sensor setup, I’ve tried multiple options but not appears to clear the surrounding quote marks.

    name: "Fishtank Temp"
    state_topic: "tele/fishtank_temp/SENSOR"
    value_template: ‘{{ value_json.DS18B20.Temperature }}’
    unit_of_measurement: '°C'

have you tried:

value_template: ‘{{ value_json.DS18B20.Temperature | float}}’

I’ve given that a try, no change unfortunately, thanks for your suggestions anyway.

Try this way:

    name: "Fishtank Temp"
    state_topic: "tele/fishtank_temp/SENSOR"
    value_template: '{{ value_json["DS18B20"]["Temperature"] }}'
    unit_of_measurement: "°C"

I use this syntax for my TH10 and it works correctly.
