Hi all,
I built an OCPP app for my own charger and figured others might find it useful too.
**The problem I had:** my charger (a Raedian NEO) is linked to a charging provider, because my employer reimburses my charging through them. I wanted to control it from Homey so I could charge on solar and cheap hours, but as soon as you point the charger at Homey, the link to the provider is gone. No more registered sessions, so no more reimbursement. Not great.
So OCPP Bridge sits in between. The charger talks to Homey, and Homey just passes everything on to the provider. Homey gets control, the provider doesn’t notice a thing, and the cards and the provider’s app keep working as before. If you don’t have a provider you just leave that field empty and it works on its own.
What it does:
- shows power, current, energy and charging status (also in Homey Energy)
- start/stop charging and set the max current from Flows
- triggers for plugging in, unplugging, charging started/stopped
- reconnects to the provider by itself if the connection drops, and lets you know if a session might not get registered
Setup is pretty simple: add the device, Homey shows you an address like `ws://192.168.1.10:9000/`, put that in your charger’s OCPP settings, paste your old provider address (or skip it) and restart the charger. Homey finds it by itself. One tip: write down the old address in your charger *before* you change it, because you’ll need it.
You need a Homey Pro (mini) and a charger that supports OCPP 1.6 (JSON). Most wallboxes from the last few years do.
So far I’ve only tested it with my own Raedian, and there it runs fine including RFID cards. If something doesn’t work: there’s an event log in the app settings with a “copy report” button, so paste that in here and I’ll take a look.
