Things I should about OCPP and WARP2 Pro?

Recommended Posts

Hi all!

I've ordered the Warp2 Pro 22kW yesterday ūü•≥¬†, and want to use OCPP 1.6j to point to the backoffice of¬†MobilityPlus¬†or Stroohm so they can manage the billing of my charger.
I have no experience with OCPP or how good this standard is and the implementation of Wrap2 of the standard.
Can anyone give me information to up my chances of getting this done successfully?
Any stories to share?

Boyond this I've read that recent firmwares support MQTT autodetect for Home Assistant. Will check this out for sure.

Update: it seems the actual processor will be https://www.lastmilesolutions.com/

This should just work because OCPP is an open standard, so every server and client implementation should be able to talk to one another. There are however some OCPP related bug fixes that will be released with the next firmware (~ this or next week).

As far as I know, nobody has tested the implementation against lastmilesolutions.com yet. So please report back when you had the chance to test this.

Yes, did see that: - Fix OCPP connection not being reestablished when closed by the server with specific timing

@rtrbt they answerd my question:

 

Good afternoon Filip,

We inquired with the back office system (LMS).
Unfortunately, Tinkerforge GmbH does not yet have a certificate/collaboration with LMS, so we cannot currently onboard WARP2.

Tinkerforge can apply for this certificate itself. That process does take some time.


Kind regards,


Can tinkerforge inquiry what would be the minimum requirements?

We've sent them an e-mail.

Will using EVCC conflict with OCPP?

In theory this should work. I'm not 100% sure how EVCC behaves if the OCPP server does not allow a charge to start. But I have not tested this in a long time, maybe it works just fine now.

If I understand it correctly the feature "LocalAuthListManagement" should be enabled/implemented for this?

The LocalAuthList allows the charger to authenticate some NFC tags without asking the server. However the server is still notified of the transaction. Also this is not implemented yet. We currently support the Core and SmartCharging profiles.

If I understand you correctly, you want to charge without the server being notified, if you use a locally configured tag? That is AFAIK not possible with OCPP, because the server is at least notified about every transaction and can use a RemoteStopTransaction request to stop a running transaction.

A possible solution (depending on your provider) could be to register a (set of) NFC card(s) that you use for local (payed by yourself?) charges and another (set of) NFC card(s) that you use for "official" charges.
