[vz-users] Landis Gyr E230

[Karl Kashofer]

Hi all !

I have a landis gyr E230 which i can successfully read using an IR head,
What i get is:

> /LGZ5ZMR110AR.K53

As you can see the power line consumption is in 1.8.0 while my solar
panels feed into the grid on 1.8.2.

I can see the current power running over the three lines in 31,51,71.7
and 16.7.

However, i could not yet find a way to determine if i am currently
consuming line power or feeding into the grid. I can not see any
indication of the direction of the current flow.

So, my question is: Is there any way to determine if i am currently
consuming or providing electricity ? Is there any other command i could
send ?

Here are the commands i am sending in my reading script:

> function callmeter {
>   sleep 1
> #  echo "Sending start sequence"
>   printf "\x2F\x3F\x21\x0D\x0A" > $device
>   sleep 3
> #  echo "Sending request sequence"
>   printf "\x06\x30\x30\x30\x0D\x0A" > $device
> }

Any help appreciated,
Regards,
