The Rpi is working now with the emoncms thing running. If we want to get the voltage of all 3 phases then we can use analogue pins 4 and 5 (http://openenergymonitor.org/emon/emontx/reference & http://openenergymonitor.org/emon/node/531) and a bit of circuitry with the AC <-> AC adaptors that open energy monitor sells (http://shop.openenergymonitor.com/ac-ac-adapter-uk-plug/). | |||
This is the circuit we'd need to build http://openenergymonitor.org/emon/buildingblocks/measuring-voltage-with-an-acac-power-adapter | |||
