Communication / Bluetooth

MiniHPC has the ability to read data from compatible Bluetooth devices in the household that are nearby.
From these devices, it is possible to read the spatial air temperature T1 and humidity, from which MiniHPC then calculates the dew point and adjusts the cooling threshold temperatures accordingly, so they do not exceed the dew point and cooling does not cause condensation problems on surfaces.
Reading data from a compatible BT device must be activated in the menu 2.6 Dew point / BT sensor

Currently supported is, for example, the Xiaomi Mijia (LYWSD03MMC) Bluetooth sensor with custom firmware ATC_MiThermometer, or another BT sensor flashed with the custom ATC firmware.

The BT sensor can be flashed to custom firmware by simply uploading new firmware via the web flasher TelinkMiFlasher in the case that the Xiaomi Mijia contains an older version of the original firmware up to version 1.5.

In the case of the new version of the original firmware 2.1.1, the procedure is more complicated. We recommend studying the GitHub pages of the firmware creator for more information, or watching the following video.

After uploading the custom firmware to the BT sensor, it is necessary to set the parameter Advertising type to PVVX (custom).
