Emulate Wallbox OCPP to integrate with Octopus
Hi Andy, did you get any further with this? I'm trying to do the same.
Do you know what what Model, Vendor & firmware version Wallbox send, as it may be as simple as recompiling the firmware.
Alternatively I was going to try and reach out to an existing Wallbox owner, and try and reverse engineer the protocol.
Hi Stuart,
I dont unfortunately, I had the same thinking of it perhaps being the model/vendor information. I dont know what is sent and been searching the web to see if anyone has recorded the information being sent.
I found the above information from a Home Assistant page for OCPP, I tried in Octopus to set the Wallbox which meant Octopus give you the details to put into Wallbox for OCPP connections, but when I did that it still didn't activate, so may be as you mentioned either the Model/Vendor information sent over or perhaps the Metrics information missing something. I dont have an OCPP receiver so haven't tested what openevse actually sends.

I am looking at how to integrate with octopus energy who I have seen plenty of people looking to integrate with and got thinking that as they support the wallbox devices using OCPP there may be a hack way of integrating Openevse.
In essence I was looking to see if anyone has already tried this and if it worked already, but if not if there was a way of telling octopus that the device I am connecting is a wallbox, get the OCPP details from them and then plumb them into my Openevse device and get Openevse to emulate a wallbox so octopus would not see any difference and we could integrate very quickly using this method while they continue focusing on integrating the cars instead of supporting the chargers?
I did find this on another website which shows what seems to be the details Wallbox sends to OCPP, I wasn’t sure if there is any charger specific information I would need to replicate to tell octopus the Openevse was a wallbox through OCPP?
