I was playing with a couple of brand new H5074 devices and realized that the iOS app now includes two new charts, Dew Point, and VPD.
The new devices report as hardware version 2.00.01 firmware version 1.00.01. My older devices all report hardware version 1.00.01 and firmware version 1.01.00.
The pressure and dew point are available in both the new and old H5074 devices, but not with any of the other units I’ve got connected. (H5177 or H5075)
I’ve not been able to find details on the data. I don’t know if it’s packed into the BLE advertising data, or only available in the connected download data.
