Hi,
after one day of trial and error I managed it to flash the ESP32 bluetooth with openMQTT Gateway and integrated it in openHab as a Generic MQTT.
When XIAOMI Mi Jia 2 the little Thermometer Thing is sending the values I´m able to see the hole message like this:
{"id":"A4:C1:38:18:8A:BA","name":"ATC_188ABA","rssi":-56,"model":"LYWSD03MMC_PVVX","tempc":25.34,"tempf":77.612,"hum":43.02,"batt":88,"volt":2.997}"
So last step in openHab3 the item is showing NULL - what to do now to filter only the tempc Value. I thing it´s a json hack.
How is the right code to get the temps value
Thank you
