I have replaced my knackered old CurrentCost monitor, with an emonPi & emonTx, so that I can monitor these things: -
my electricity usage
my EV’s electricity usage
my SolarPV’s generation
my Solar Thermal (hot water heating) - in time
Perhaps also taking actions upon various stats or events. I had hoped that my Domoticz (http://domoticz.com/) installation would “see” the emon devices, but nope 
Has anyone here on this forum got any ideas on how I might achieve some integration into my pre-existing Domoticz system?
