In My Acurite & Weather Underground: Rain during day or 24 hour counting periods get zeroed out or reset for no reason. This has been happening ever since I replaced the Smarthub with the Access. The problem could be in The Access firmware or the Acurite servers. I think the same issue occurred with the Smarthub at one time, but I thought Acurite solved that since I hadn't noticed it on my Smarthub at all. I'm thinking about just changing back to the Smarthub and returning the Access to Acurite until they get the issue fixed.
