Thanks Flapp.
Bothers me there is no clear answer if the wireless link is two way or not.
Some teeaged hacker or moke could cause a lot of mischief if they got in to the system..
1-way or 2-way communications depends on which protocols HECO is using. Some are simple enough they don't require any communications TO the meter. They are only set up to receive usage reports. if they decide to use a fully capable network protocol like TCP/IP, then they have the ability to send requests to the meter for diagnostics and inventory audits.
The data is normally sent to an aggregated server for your neighborhood where you then have access to view your own data. When it comes to customers having access via the Web, it's a given that your data is at risk of unauthorized access no matter how secure they think their system is. Never underestimate the motivations of a disgruntled ex-employee or someone else (contractor) who finds a way to make money on that data.
We had an issue where the Air Force members going on personal leave out of the area were returning to find their homes were burglarized. It began happening too often to be a coincidence. Turns out someone working in the Command Squadron where leave forms were processed was tipping off the people breaking into service member's homes while they were away on vacation or wherever.
I can see knowing the usage habits of a household could have similar applications. What time they get up, leave for work or school, get home, go to bed, and when the home is vacant for longer than a day.
