Sonoff TH10/16 | DS18b20 temp sensor | MQTT reading

---

Hi,
I can’t really figure out how I should be able to read the temperature from the DS18B20 sensor connected to the Sonoff TH10/16 flashed with Tasmoto 5.10.0a.

MQT: tele/sonoff_TH10_02/STATE = {"Time":"1970-01-01T00:00:17","Uptime":0,"Vcc":3.211,"POWER":"OFF","Wifi":{"AP":1,"SSId":"***************","RSSI":100,"APMac":"***********"}}
MQT: tele/sonoff_TH10_02/SENSOR = {"Time":"1970-01-01T00:00:17","DS18B20":{"Temperature":23.3},"TempUnit":"C"}

Actually I like to achieve what is to read the temperature into a variable and plot it into a graph like shown in this thread;
[https://forum.pimatic.org/topic/2967/option-for-wireless-modules/13] (chrizzz86 | 9 months ago).

Though that is done by using a CURL-statement and I wonder if I can’t read that varibale not directly in a same way as you read the status of the on/off relay??

(PS i had to tweak the curl-statement a little to make it work for me

 curl --silent http://192.168.*******/cm?cmnd=Status%2010 | grep 'Temperature' | cut -d ':' -f7  | cut -d '}' -f1

)

Second question:
A bit of topic perhaps but I also wonder how chrizzz86 got that little graph in there.
fixed

Thanks all

Hi @Jeroen With mqtt plugin like this. Uses a “regular” dot annotation for json message. Yes, there is a minor problem with name attribute, but I’ll probably fix it by the end of the year. But the principle remains.

    {
      "attributes": [
        {
          "name": "DS18B20.Temperature",
          "topic": "tele/sonoff_TH10_02/SENSOR",
          "type": "number",
          "messageMap": {}
        }
      ],
      "xAttributeOptions": [],
      "id": "tasmota-temp",
      "name": "Tasmota temp",
      "class": "MqttSensor"
    }

Thanks Wutu.
good luck with your programming. I can only express my thanks to you and ’ your kind’ who create all these tools and programs for us.
Don’t forget it’s x-mas with the CURL we have a work around!

@jeroen
I have a DHT22 connected to sonoff with tasmota 5.2.1. So far it works fine with mqtt-plugin. The pimatic graph looks fine too. As wutu says, it is important to take the right “name“ under attributes. In youre case it should be “DS18B20.Temperature“.
here my config:

 {
      "class": "MqttSensor",
      "id": "mqttsonoff130",
      "name": "Badezimmer oben",
      "attributes": [
        {
          "name": "DHT22.Temperature",
          "topic": "tele/sonoff/SENSOR",
          "type": "number",
          "unit": "C°",
          "acronym": "Temperatur"
        },
        {
          "name": "DHT22.Humidity",
          "topic": "tele/sonoff/SENSOR",
          "type": "number",
          "unit": "%",
          "acronym": "Feuchtigkeit"
        }
      ],
      "echo": {}
    },
