Hi, The Smartmeter (in Dutch de slimme meter) is an electricitymeter with a serial port.
The energy company installs it in all the Dutch houses (during the coming years).
Many owners of houses with solar cells have already such a meter.
The meter can be connected to the gas meter.
So it's possible to get in one message the gas and electricity usage.

Electronically it's simple. You use a modified USBtoSerial (RS232) cable, connected directly to the RbP.
Every 10 seconds the meter produces some ascii strings with informaiton about the energy usage .

You can look at the dutch article: http://gejanssen.com/howto/Slimme-meter-uitlezen/

Regards.

Now I hope someone can help me with connecting this meter to PIDome.

I've posted the same question in detail on the PiDome forum under Hardware/Devices.
http://forum.pidome.org/viewforum.php?id=13

Maybe a new topic?

I want to connect a smartmeter to Pi Dome controller.
I have a USP/Serial cable connected to the powermeter.
With another program I have seen that the Raspberry receives information.
The light on the serial-usb cable is flashing every 10 seconds. That means that data is available.

Now I have installed Pi Dome. This works nice and has a good performance.

At this moment I don't know how to go further.
I have installed some drivers. Adjusted the baudrate and now I get the message "Waiting for gateway" and I don't receive values in the logging.
