I have a OpenEVSE Plus I bought March 1 2013. it has worked great. It has the RBG display no real time clock.
Will the new WiFi connectivity kit work with my setup?
Based on the age, the Wifi would work however you would have limited monitoring capibilities. You could upgrade the display to get a temperature sensors, but the current measurement feature was not added until the OpenEVSE v2.5 board.
Thanks for the information. I don’t care that much about the temperature but the current measurement would be nice. I guess I will pass for now.
