I replaced my SmartHub this weekend with the Access. I've never had an issue with the SmartHub. The Access will connect and I'll see the data in the web portal but then after the initial upload it will drop the connection. I had a 4 hour block yesterday that it was reporting consistently but now it's dead again. I have tried resetting my router, pulling power and batteries from the Access, replacing batteries with other new batteries. It will just not stay connected tot he internet and this was never a problem with the SmartHub. I tried to hook the SmartHub back up but the portal said it's no longer supported.
