Hi All,
yesterday I received my kit to start metering the power.
when I wanted to install the clamps in the electricity cabinet, I noticed that the house works on 3x220V. (It's a rented home so I didn't pay attention to this upfront).
How should I connect the clamp? all 4 wires in the clamp? or should I order some extra clamps, and connect every cable separately?
And second, when I want to create a dashboard in emoncms, i get the error:
Warning: stream_socket_client(): unable to connect to tcp://: (Failed to parse address ":") in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\emoncms\Modules\feed\engine\GraphiteTimeSeries.php on line 30 []
I'm running a windows server 2012 with apache, php and mysql. The raspberry pi as a gateway isn't active yet, could that be the problem?
thanks in advance,
David
Re: starting with the openEnergyMonitor
Current Transformers: If you put all three phases through the c.t, you will effectively measure the neutral current and in an ideal situation that should be zero! So that's the wrong answer. You need 3 c.t's and a 3-phase sketch to measure the total energy passing by. You can read more about the 3-phase supply in Building Blocks.
I can't answer your server problem, hopefully someone else can.
Re: starting with the openEnergyMonitor
Thx Robert for the information, I will order some extra CT-clamps then and continue to figure out the next steps to get the system working.
no one else some information about the stream_socket_client() error?
