Alfen setup?

[bobf41]

I have OCPP setup and configured my connected Alfen EVE Mini S Line like ws://homeassistant.local:9000 but get no info. Same for http://
homeassistant.local is retrieved successfully and tried the ipaddress as well.

@Rep-Hueman has tested OCPP with Alfen chargers, (Alfen - Eve Single S-line and Pro-line). See issue #19.

@bobf41, can you make a screenshot of how you configured your charger?

[bobf41]

Model: Eve Mini (S-Line)
Plartform: NG910
Hardware version controller board: G-00
Hardware version power board: F-FEDAULT
Software version controller board: 4.15.0-3910
NFC Reader 1 hardw. version 217H

These are the supported Subset of measurands

"Energy.Active.Import.Register"
"Current.Import"
"Current.Offered"
"Frequency"
"Power.Active.Import"
"Power.Factor"
"Temperature"
"Voltage"

Sometimes you need to restart the charger.
And then wait 10 minutes and then start the first charging session.
If it's good you see all the value

Thanks I will try connecting a car.
any idea if it will be possible to connect to an official Backoffice and to Homeautomation at the same time? I guess not since it is set through the same parameters

I don't know how it works for Alfen chargers, but my Wallbox Pulsar always connects to the Wallbox Backoffice, even when a local ocpp server is configured.

How did you determine the lis of supported measurands?

Some extra screenshots of the setup on ACE Service installer that may help people with Alfen Chargers

Will we be able to have a Backoffice configured and have a config for HA?
The Backoffice is most important.

[Ascotg]

@bobf41 From what I learned, not using the OCPP implementation. An EV charger can only connect to 1 backoffice at a time, which makes sense. The backoffice (OCPP) is meant for the financial side of the charger.

However, you can interface with the Alfen over Modbus TCP protocol and set a backoffice at the same time. Here's a link to someone with that setup: https://community.home-assistant.io/t/alfen-eve-pro-ev-chargepoint-interface-via-tcp-modbus/346000

@Ascotg how did you get the ACE license? Are you an official installer or can anyone request them?

I managed to get the login by just registering on their service portal, if anyone else reads this in the future.
