Reading data from new smart meter

Other Devices & Integrations Power Management
#1

Hi All,

The electricity company just upgraded the meter in my house to a ?smart meter? which reports usage, voltage etc back by it self. This meter has an HAN port (home automation network) which can be activated, as far as I know this outputs usage, voltage, power factor etc via an m-bus(meter bus) protocol. Does anybody have any experience with this? And what would be required to get this data into my vera system?

Thanks

I would guess it would need to support one of the protocols that your Vera system supports. Which Vera product do you own?

I have not played with a HAN port. I have tried reading the radio transmissions from a smart meter using a RTL-SDR with some success. It would be nice to plug in and get that information directly.

I’ve heard of the Zigbee based HAN which is a second radio in the smart meter. For that you can get a Rainforest Eagle or other devices which will talk to it and you can collect the data via http post/get requests. There is a physical HAN port on your smart meter?

Hi,

The Dutch Smart Meter also uses a protocol based on m-bus, so maybe this can help you get started. Feel free to develop a flavor that will work for your meter based on that. The source is on my GitHub page [url=https://github.com/reneboer/Vera-Dutch-Smartmeter]https://github.com/reneboer/Vera-Dutch-Smartmeter[/url]. The Dutch smartmeter uses a P1 to USB converter cable that connects to a Vera USB. Not sure if a HAN to USB cable exists, but that may be required.

See [url=http://forum.micasaverde.com/index.php/topic,32081.0.html]http://forum.micasaverde.com/index.php/topic,32081.0.html[/url] for more information.

Have fun.

Cheers Rene

But with Vera Plus having Zigbee, this shouldn’t be necessary… except that Vera doesn’t have the second code on the bottom to “activate” with the electric company.

On the other hand, it appears the original question was about smart meters that do in fact have a physical port for a connection, so that’s a different problem.

Where are you located? If you’re in Norway I might be able to point you in the right direction…

Reading data from the new smart meter is the very important thing to learn. But first, I am also not able to get this thing. But now I get rid of from this problem by visiting https://netgears.support/netgear-genie-support/
Now I can read and take the data from the new smart meter.

I love Norway. I went there for a vacation 5 years ago. Oslo, Bergen, fjords…the place is amazing. Better yet, I loved Lillihammer, the show on Netflix.

I’m trying to get my smart meter rolling with Southern California Edison, I’ll report my findings.

If your energy provider provides daily readings on a website, another way to approach this could be to write some kind of script that grabs these values from the website.

As above, youd have to get some sort of aftermarket ecu to get rid of the afm, it would be extremely difficult to trick the factory ecu into reading a map signal

Search for the Rainforest Eagle on these forums. A plug-in is available…
