JSON for tasmota ble - connected xiaomi LYWSD0290dd04

[sommertrip]

Hi!

This is a request for help on the configuration, I don't think it's a bug.

I am very happily using homebridge with many devices over MQTT but I do have issues to get temperatur/humidity displayed fetched from a Xiaomi BLE Device.

I do have the following Setup:

• RasperryPi with 1.4.0
• Homebridge Mqttthing - 1.1.39
• Tasmota 32 BLE configured to receive data via MQTT Console report:

I´d like to get the temperture and humidity displayed in homekit apps. the current JSON in homebridge in the temp section is.

I´ve tried several other configs but can´t get it to work

Maybe a Bug?

This works well for me in a similar setup

   {
            "accessory": "mqttthing",
            "type": "temperatureSensor",
            "name": "Bathroom Temperature",
            "topics": {
                "getCurrentTemperature": {
                    "topic": "tele/mirrorheater/SENSOR",
                    "apply": "return (Math.round(JSON.parse(message).BME280.Temperature*2)/2);"
                }
            }
        },

Hi thx, but didn´t help still receive the following message [6.4.2022, 15:46:00] [homebridge-mqttthing] This plugin generated a warning from the characteristic 'Current Temperature': characteristic value expected valid finite number and received "NaN" (number). See https://git.io/JtMGR for more info.

NaN means "not a number". Maybe you need to change the topic and BME280

I was able to configure this sensor like this. Homebridge console throws warnings, but it works. { "accessory":"mqttthing", "type":"temperatureSensor", "name":"Temperature BLE Living room", "url":"mqtt://localhost", "topics":{ "getCurrentTemperature":"tele/tasmota_D6376C/SENSOR$.LYWSD03c61721.Temperature", "getStatusLowBattery":"tele/tasmota_D6376C/SENSOR$.LYWSD03c61721.Battery" } },
