There is a test version available.

Xiaomi Mijia LYWSD03MMC ESP32 support

Here is the implementation for tests purposes: https://github.com/1technophile/OpenMQTTGateway/tree/BLEConnect Now during the scan OMG store the different models of devices, after the scan if we have found a LYWSD03MMC we connect to it and retrieve the data. The time between each connect is BLEinterval This implementation helped me, thanks to @jschaeke and @francisp for the identification and the tests.
