OCPP AND Home Assistant
OpenEVSE Support
We would suggest the excellent home assistant integration below, it uses http instead of OCPP

Thanks but that only works with OpenEVSEs. I have a different type I want to integrate into the HA control and using the same protocol for all has obvious advantages - if I can get it to work of course.
Back to my question then. are HTTP and OCPP mutually exclusive?

HTPP web configuration portal is always available no matter what protocols are running.
You may have control conflicts if you are sending Manual override or HTTP API commands while OCPP has control of the station. If you need both you would likely need to enable OCPP, issue OCPP commands then disable OCPP before issuing HTTP control commands.
The OpenEVSE Home assistant integration is fantastic, you will probably have better luck if you use that for OpenEVSE and use whatever is available for non-OpenEVSE stations.

Thanks, that does kinda explain the odd behaviour I saw when I tried enabling OCPP on one of my OpenEVSEs.
I like the concept of OCPP. A standard that can be used with all different EVSEs, but I understand the chances of the exact same 'standard' on all different EVSE's is slim, so…
Maybe you're right and I'll just use the HA integration over HTTP and buy more OpenEVSEs rather than any other.

I am interested in trying to control my OpenEVSEs from HA via OCPP. When I first tried this and enabled OCPP on one EVSE, it appeared to stop responding to commands via the web GUI.
So, first question is if HTTP and OCPP are mutually exclusive, or should they both function simultaneously?
I don’t mean literally simultaneous commands, but will the unit respond to either command protocol, or if OCPP is enabled on the unit, can the web GUI no longer be used to control operation?
