Deleting trend data in app

I have both temp control (308) and humidity(200) linked to the phone app. Can you delete data?. Is there a way of having average. I use when travelling away from home salami fridge. Thanks j

Sorry, the data can only be cleared through the INKBIRD app - ITC-308-WIFI / IHC-200-WIFI - ‘…’ in the upper right corner - Remove device - Disconnect and wipe data.

Then please reconnect the device.
If you want to get the average, please export the data and calculate the average.
