I assembled an openevse v5 with wifi firmware 2.7.6 and I’m getting the “Energy” counter measuring wrong!
It measure the power (A) ok and send it to emoncms ok in Wh but this counter “Energy” (session accumulator) in the web interface and in emoncms it’s about half of the real value!
What could it be?
What is the version version of your open_evse controller?
Have you set “Level2” charging mode?
Does the WiFi interface kWh match the kwh on the LCD display?
Please could you post an image of the LCD display and a screen shot of you emoncms input process setup. Please post images directly on the forum rather than using a external hosting site.
Ah right, individual OpenEVSE controllers were shipped with the default firmware. We have now started shipping all with EU firmware.
No need unless you really want some of the new changes (mostly minor bug fixes). The main difference is just the default setting which you can easily change e.g Level 2.
