Trying to wrap my head around OCPP and what it would mean to me personally if I had an EV and bought a wall charger for it. My understanding is that it would be mostly irrelevant for my needs. It could theoretically be helpful if trying to integrate it in to a Solar Energy system but otherwise for a home consumer I don't totally understand what the benefit might be.

One mentioned benefit is that if you use software with your charger to control certain functions and that software provider goes bust, you won't be left high and dry. Initially I interpreted 'software' to mean the app for a smartphone for controlling the charger for things like scheduled charging, or setting a maximum charge or maybe setting different power levels of charge. If the company that sold me the inverter and by extension provided the app, went out of business, that would be bad in terms of the app eventually becoming obsolete and that seemingly would make the idea of OCPP compliant wallboxes attractive, however I've never heard of generic charging apps for consumers that will use OCPP to control a wallbox for basic functions like I describe. It sounds like the 'software' being referred to is for more advanced use cases like for example, integrating with a solar energy system or maybe a business running multiple charger points and wanting automated billing from various chargers of various brands.

Would the charger being OCPP compliant actually help an average person in the event that the charger company goes out of business and the app becomes obsolete or unobtainable from mainstream app stores?
