My EmonEVSE has been working well for a year in Eco mode, but in the last couple of days, it is sending about 1kW too much power to the car.
Looking at my chargepoint’s OpenEVSE webpages, I see the MQTT setup still being as I expect, and my MQTT topic is being sent from my emonPi without problems.
In the OpenEVSE>ChargeMode section I am switched to Eco and as I write the ChargeMode values read:
Solar: 621W 2s | Charge Rate: 6A.
Solar: 800W 3s | Charge Rate: 7A.
Solar: 1146W 2s | Charge Rate: 10A
Solar: 2161W 1s | Charge Rate: 19A
…and these solar values do correspond with the MQTT feed from the emonPi
I would expect these amperages to be about 4A smaller, and historically they have been.
I have tried repowering the emonPi and the emonEVSE, and changing and resaving the MQTT settings in OpenEVSE, with no improvement.
Can someone suggest a next step please.
Many thanks, David.
