Error with DS18B20 Temperature Sensor

Is it regarding the missing Humidity, because it's only Temperature Sensor?

Hi
On my side, I only have a DHT11 based device. The typical MQTT message looks like this:

{"Time":"2020-10-31T15:52:28","DHT11":{"Temperature":18.5,"Humidity":34.0,"DewPoint":2.3},"TempUnit":"C"}

I suppose that since you've no humidity and only temperature sensor the message will look like:

{"Time":"2020-10-31T15:52:28","DHT11":{"Temperature":18.5},"TempUnit":"C"}

Or maybe

{"Time":"2020-10-31T15:52:28","DHT11":{"Temperature":18.5,"Humidity":null,"DewPoint":null},"TempUnit":"C"}

If there is only one sensor I can see in the code that indeed it can behave wrongly, I'll look at it.

In the mean time could you please write here the MQTT message content you're receiving from your tasmota enabled device?

I think I have a kind of answer from the tasmota doc
The message should look like:

{"Time":"2020-10-31T15:52:28","DS18B20":{"Temperature":18.5},"TempUnit":"C"}

Apparently there are cases when tasmota can have multiple DS18B20 sensors, it is not yet handled so I hope you only have one. I'll fix the problem.

Thats my Mqtt message

SENSOR = {"Time":"2024-02-07T18:05:03","DS18B20":{"Id":"C265801E64FF","Temperature":56.8},"TempUnit":"C"}

Ok, new release v0.12.0 published, you can now use temperature instead of sensor in your homebridge accessory json config file.
I'm closing this issue but feel free to re-open if it is not working!

Hi, thanks but not working. Maybe missunderstanding on my side.

See my config
{
"accessories": [
{
"name": "Temp. Warmwasser",
"type": "temperature",
"url": "mqtt://192.xxx.x.xx:1883",
"topic": "tele/Temp._Warmwasser/temperature",
"accessory": "mqtt-tasmota",
"plugin_map": {
"plugin_name": "homebridge-mqtt-tasmota"
}
}
]
}

Your config should look like this:

        {
            "accessory": "mqtt-tasmota",
            "type": "temperature",
            "name": "Temp. Warmwasser",
            "url": "mqtt://192.xxx.x.xx:1883",
            "topic": "Temp._Warmwasser"
        },

where Temp._Warmwasser is the MQTT name setup in Tasmota interface
You probably don't need a plugin map entry
If you're to build the topic yourself, the end is probably SENSOR and not temperature as you can see here
