This device is out of the box compatible with OpenMQTTGateway / ESP32, the gateway connects to it every 10 minutes approximately so as to retrieve the temperature, humidity, battery and voltage data.

You can also change the firmware of the device easily by following the tutorial below, with this custom firmware, the device data are read every 55s. It enables to read the data with an ESP32, an HM10 + ESP8266 or an Arduino MEGA.

 

Note that the flashing process takes less than 5minutes and is done over the air (impressive :-)).
