Reading data from new smart meter

(1/3) > >>

Henninne:
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 https://github.com/reneboer/Vera-Dutch-Smartmeter. 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 http://forum.micasaverde.com/index.php/topic,32081.0.html for more information.

Have fun.

Cheers Rene
