How to monitor different energy souces with OpenEnergyMonitor

Submitted by mark.gue on Mon, 15/09/2014 - 10:24

I need to monitor different consumption types within an apartment and send them to a remote server.

To be precise, I need to measure:

- the overall consumption of the apartment (http://shop.openenergymonitor.com/100a-max-clip-on-current-sensor-ct/)

- consumption related to some appliances (I should use smart plugs or similar)

- Temperature

- Gas consumption

And I need to gather all these data in a Gateway and to send them to my remote server.

The question is, with the tools of OpenEnergyMonitor, it's possible get these data (or mosto of them) and to send them on my server with an almost ready-to-use solution?

I read that I should weld some components, but since I should do it for a lot of apartments I'd prefer to avoid it.

Thanks in advance,
Marco

Is the installation single phase or 3 phases? How many apartments, are they all in one building and is Ethernet available to each? Is a socket outlet available very near to the electricity distribution panel in each apartment?
We can do overall consumption, temperature & gas consumption, for that you would use the fully assembled emonTx V3. You will need to add some means to obtain data from the gas meter, that might simply be a magnetic reed switch. The smart plugs may be a problem, because unless the protocol they use is published and you can receive the data at your gateway, integrating those might be very difficult, if not impossible. Depending on the number of CTs required to measure overall consumption, the emonTx might be able to measure one or more appliances individually if each has its own feed from the distribution panel.

A single-phase emonTx V3, with a Raspberry Pi acting as the gateway, is almost ready to use - you will need to load a sketch that incorporates the gas measurement. If the Raspberry Pi can receive the data from your smart plugs, then you have a solution to the individual appliances problem. All the data would be sent to your server where you could install emonCMS.

Using ZWave smart plugs, with openHAB (www.openhab.org), you will be able to monitor the smart plugs in openHAB and faily easily transpose those readings to HTTP requests for sending to an EmonCMS instance.

Doesn't necessarily have to be ZWave plugs, as there are literally dozens and dozens of devices/protocols supported by openHAB, but ZWave is probably the easiest out-of-the-box (that I know of).

Are you guys familiair wth the smart electricity meters where you can connect to the P1 port RJ!! (DSMR 2.x, 3.x en 4 implementatation of NTA8130)

The smart gas meter is connected to the electricity meter and both info you can get of the P1 port.

Any suggestions ?

Greets,

Hello all.

Is it someone succeeded to connect the P1 port on energy monitoring?

Through a USB Serial converter can I value P1 port readout on openhab.

Is it possible to send this data to open energy? Or can it directly without going through openhab?
