I’m intrigued but that is one of the worst (least technical) product pages for a very technical product that I’ve come across. My biggest concern was that it has no mention of compatibility, it just says it connects to the smart meter via zigbee but aside from the obvious fact that zigbee is just the network protocol and does not necessarily mean all smart meters use the same layer 7 details, I don’t even know if my smart meter has zigbee to begin with! Ah, I just found a FAQ page for the site not linked from the product page that answers the compatibility question.

Also, I wouldn’t have known the product exposes an API I could use to programmatically get the (XML-only?) usage data in realtime over the network if you hadn’t told me, the product listing makes it look like it’s just a screen (and the faq doesn’t have anything about connecting to the device programmatically).

Anyhow, thanks for brining this to my attention! This might be exactly what I was looking for!

I received my device as part of a pilot program with my utility company.

Check with your electric company first, and also look at your local library -- my brother was able to borrow one from there to check compatibility first.
