UPDATE: On November 7th I added an temperature & humidity logging sensor (https://www.amazon.com/gp/product/B07DWMJKP5/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1_). It can export to an CSV. You can find the last export of the raw data in CSV here: https://drive.google.com/drive/folders/1WH3USS3t79BpEgxJUGrjw8HDdDVz4-L9?usp=sharing
It's reading a high of ~35.5f and low of ~32f with 81% humidity down to 60%.
I've been taking photos of the progress and you can view the on-going progress here: https://photos.google.com/share/AF1QipO04vEJR-ih-xKRgR0riYC-eZTiJJ-UONwMcxVvnauJlT91uLzqf1wa6D4AI36tuw?key=MHNQc25ha2pzZjRrbUR4bEtqVXdVWVhqaDZyaGh3
Is this the exact model you use?
It only stores it for 20 days in the device, but the phone app is storing it for longer?
