Seemingly random current / kWh charged readings

Over the last couple of months, my OpenEVSE unit has started throwing the occasional wobbly - putting very high current figures out and integrating those so that the claimed kWh charged is unfeasibly high. Apparently I charged 252kWh on 31st May and 196kWh on 10th June! Mostly it’s working correctly; any ideas?

Mm that’s strange. Could you plot the openevse power reading on the graph? Do they look normal?

Also are you providing VRMS from the emonTx / emonPi via MQTT or are you using the preset value of 240v?
