Hi all,

I've built a system with 3 T315 and 6 T310. Day to day they work really well, the temperature and humidity alerts trigger push notifications if they go out of range etc. 

What I am struggling with is long term data saving. If I open the tapo app on the house WiFi, I get a graph of the previous 24 hours. If I go to "view all", I get data for the past 24 hours, but if I select month or year it shows "There is no data yet" (I've left it for about 6 weeks to see if the data appeared in the month view after a month, but it hasn't!). Also, if I go to the download/email a data backup it emails me an empty dataset (file contains row headings only)

Separately, when I'm out of the house on phone data (and off the local network) I can see the most recent data point, but no access to the 24 hour data, literally just the last number the app has seen. Is this correct behaviour (as in should I have to set up a VPN or equiv in to the local network to see it?) 

Many thanks, and let me know if you need more info. Firmware version above is for the T315, I haven't added the T310 or H100.
