Some of you guys are such Negative Nancies.
The SmartHUB hardware was getting pretty long in the tooth. There just wasn't much memory or other resources there left to work with.
The Access resolves that issue.
It will be necessary for the 433MHz Atlas.
There have been some technical changes that will make network interception of the data more difficult, if not impossible. Data is encrypted going to myAcurite. Data to wunderground is currently not. That could always change, though.
Also, data seems to be stored and sent to myAcurite in 5-minute intervals. I imagine this is to cut down on the traffic and processing on their end. Data to wunderground is still sent "rapid-fire", though. Again, this could always change.
So in its current form, you could always sniff the wunderground data.
