The Bluetooth Thermometer Hygrometer with Screen (H5075001) cannot be combined directly with the Govee Wi-Fi Thermo-Hygrometer model H5179 as the H5179 is a Wi-Fi device and the other is a Bluetooth device. Whilst both can be monitored via the Govee Home App, they are different types of device with different connection types and cannot be operated as a combined system. The app supports both devices, but separately and not in combination.
