Wallbox + Home Assistant + Charge Control

[trinitron79]

I've been able to get working / configured in Home Assistant + OCPP (V0.10.4).

However I'm trying to figure out how to NOT have OCPP "Lock" the Wallbox after every use by default, it's just not needed in my home.

I tried a automation that works but a little slow. Ideal would be to just have it always on as default.

I looked at the "services.yaml" in /config/custom_components/ocpp but that didn't seem to be the spot. Is this something that can be configured somehow?

Same here.... Can someone confirm that this is working? Enabled in Wallbox portal including ws://x.x.x.x:9000 and installed the integration (latest), but portal is only trying to connect. Logs can be provided (if I know what to do)

Sadly I never really figured it out and moved to EVCC.

I did get the automation to work but wanted something a little more automated with extra solar.

It will ONLY unlock if a car is connected, so I used the connection status to change the lock state to unlocked. That worked well *assuming HA is running.

This might be worth a try... Please note I used ChatGPT for this, it looks like it could work.

Prompts:
Looking at https://github.com/lbbrhzn/ocpp how would I keep a wallbox charger from locking itself in the yaml file
2nd ask:
where does authenabled = false go

Where AuthEnabled = false actually goes
1️⃣ It is an OCPP configuration key

In OCPP 1.6, AuthEnabled is a standard configuration parameter on the charger:

AuthEnabled = true → charger requires authorization (RFID / remote start)

AuthEnabled = false → charger allows plug-and-charge (no authorization)

This setting lives inside the charger, not in Home Assistant YAML.

2️⃣ How to set it in Home Assistant

Use Developer Tools → Services (or an automation) and call:

service: ocpp.configure
data:
devid: wallbox_id_here
ocpp_key: AuthEnabled
value: "false"

⚠️ Important:

devid must match the charge point ID shown in the OCPP integration

value must be a string, not a boolean

If the charger accepts it, it will reply with Accepted and store it internally.

3️⃣ Make it persistent (recommended)

Some chargers forget configuration after reboot.
To ensure it stays disabled, create an automation that sends it when the charger connects:

automation:

• alias: Disable OCPP Authorization
  trigger:
  • platform: event
    event_type: ocpp_connected
    action:
  • service: ocpp.configure
    data:
    devid: wallbox_id_here
    ocpp_key: AuthEnabled
    value: "false"

This re-applies it every time the charger reconnects.

Thanks a lot for your prompt response... Let me check this and see if I'm capable to implement this ;-) Otherwise I will focus on EVCC also

It works with the Copper SB. You need to add the wallbox in ocpp with the same id/identity. You need to select only a few measurehands like https://home-assistant-ocpp.readthedocs.io/en/latest/supported-devices.html#workaround
You need to unlock before enabling charge control. You can also on the Wallbox app add a schedule like 00:00 to 23:59 then no need to unlock.

I had a similar issue with a ProjectEV charger in that Plug and Charge would not start automatically even though auth turned off. I overcame this with a simple automation that looked for a Status Connector change to "Preparing" which then turns on Charge Control.
