Data from each meter includes voltage, current, power, reactive power, apparently power, phase angle, power factor, total harmonic distortion for both current and voltage, and frequency. Most of these measurements are available for each phase, as well as between each phase, along with their totals and averages. See [[MQTT Topics#Energy Monitoring|MQTT Topics]] for more details these.

To keep everything as similar as possible between the installs, each of the enclosures contains the same components detailed in the table below.

* Openenergymonitor.org
* Current transformers in place, forgot to note down models
* Owl wireless meter? Not much use if can talk to USB over Linux
* Nanode
* Open energy monitor show voltage sense using 9v ac-ac wall wart (?need one for each phase?)
* Push to cacti
* Query form irc
* Possible led display either flashed on led matrix or own display allways on?

** plausible way to do CT monitor using 2 RFM12B nuts, would mean not stuffing a nanode in the cupboard and losing access to spare pins

We have installed four SDM630 energy monitors around the space, funded by the Power Monitoring Pledge Drive. Each monitor is DIN mounted in a small enclosure next to its respective distribution board (See Power).

Data from each meter includes voltage, current, power, reactive power, apparently power, phase angle, power factor, total harmonic distortion for both current and voltage, and frequency. Most of these measurements are available for each phase, as well as between each phase, along with their totals and averages. See MQTT Topics for more details these. All 64 metrics are published sequentially with a few seconds gap between every 8 metrics. The metrics are then fed into Prometheus so they can be graphed with Grafana.

To keep everything as similar as possible between the installs, each of the enclosures contains the same components detailed in the table below. Each of the distribution boards was fitted with a C6A MCB, with the exception of G5 (the only single phase feed), which uses a single C6A RCBO. The current clamps are fed through a separate coupler/conduit to reduce interference.
