Hi all, In case it is helpful to others here is a sample output of the V2G metrics populated for the Leaf from a recent session. Note I've opted for presenting the Chademo voltage, current and power output (as the grid voltage and inverter efficiency is not known -external to car- but nominal grid voltage could be set with a parameter and then calculated). v.g.climit 19.8939A v.g.current 7.5A v.g.duration.empty 533Min v.g.duration.range v.g.duration.soc v.g.efficiency v.g.generating yes v.g.kwh 0.0562549kWh v.g.kwh.grid v.g.kwh.grid.total v.g.limit.range v.g.limit.soc v.g.mode standard v.g.pilot yes v.g.power 2.8275kW v.g.state exporting v.g.substate onrequest v.g.temp v.g.time 104Sec v.g.timermode v.g.timerstart v.g.type chademo v.g.voltage 377V Michael, is it possible to have v.g metrics added to the V2 server message format for incorporating into the ovms app? Is it worth having a parameter to indicate car support for V2G functionality? Cheers Derek
