Are your charge points able to support OCPP, if not do you have any plans to develop anything ?
OpenEVSE has an extensive API to control all aspects of operation. OpenEVSE does not directly support OCPP but is capable of interfacing with an external OCPP device.
OpenEVSE does not currently have any plans to develop OCPP software.
I can see some value in having an OCPP interface to OpenEVSE. I'm thinking the quickest way to hack this together is to create an external protocol converter by taking an open source OCPP java library (https://github.com/ChargeTimeEU/Java-OCA-OCPP ) and running it on a RaspberryPi-class processor.
