Earn ERE's with your Alfen charger
Can I connect my Alfen to Joulo for ERE registration? Yes. Alfen Eve models are MID-certified by default and directly eligible for ERE. There are two routes: connect automatically through a cloud provider (50five or Eneco), or connect via OCPP with MyEve and Service Installer.
Careful • already connected to another OCPP backoffice?
Is your charger already configured to an existing OCPP backoffice (for example from your installer, charge-card provider or energy supplier)? Then be careful making changes. A charger usually connects to one backoffice at a time, so switching to Joulo disconnects that link and stops the services relying on it (public charging, expense reimbursement, monitoring). Not sure whether you're allowed to or want to change it? Check with your installer or current provider first.
How ERE's work with Alfen
Every kWh you charge at home with renewable energy earns you ERE's. Your Alfen charger's MID meter measures the exact energy usage and sends it to Joulo via OCPP. Joulo registers this at the NEa and you receive your payout • automatically, no paperwork.
Two ways to connect your Alfen
Pick the route that fits you: through your cloud provider, or directly via OCPP. Both deliver the same ERE registration.
Via a cloud provider (50five or Eneco)
Are you with 50five or Eneco? Then connect through that provider. No installer needed.
50five
Connect automatically with your 50five account.
Eneco eMobility
Connect automatically with your Eneco account.
Via OCPP
Not with 50five or Eneco? Connect directly via OCPP with the ACE Service Installer.
What you need
- ✓A Joulo account (free registration)
- ✓Your charger's Charge Point ID: the name on the top line in the ACE Service Installer
- ✓Service Installer access (ACE)
- ✓MyEve app and temporary charger network access
First: bring your charger online
How you do this depends on your model's age. You only need one of these two.
Before March 2023: install a network card
These older Alfen Single models usually have no WiFi. Open the charger with Service Installer access and place a network/SIM card so it can get online. This is the most technical part.
From March 2023: temporary WiFi via MyEve
Power-cycle the charger. You then get roughly 15 minutes of WiFi you can join with the MyEve app to bring the charger online.
Read the official MyEve explanationStep-by-step: connect via local WiFi (March 2023 and later)
- 1
Activate the charger's WiFi
Switch the charger off at the fuse box (in the meter cupboard) and back on after 20 seconds. The charger now broadcasts a local WiFi signal for 15 minutes.
- 2
Open the app
Open the MyEve app or the Eve Connect app on your smartphone.
- 3
Add a device
Tap the + (plus) icon to add a charger and choose to connect wirelessly.
- 4
Make the connection
Choose to log in manually instead of scanning the QR code (unless you have the password card to hand).
- 5
Login credentials
Enter your ACE number (the serial number) and the default password from your password card.
- 6
Select WiFi
Scan for nearby networks and select your own WiFi network. Enter its password to complete the connection.
Then: configure OCPP
Which steps you follow depends on your model number, on the type sticker: it starts with AHP or NG. An NG you can set up entirely from the MyEve app on your phone; an AHP needs the ACE Service Installer on Windows. The Joulo connect wizard asks for the Charge Point ID at the end: the name your charger reports itself under. In the ACE Service Installer that is the name on the top line; in MyEve, take the object number from the sticker • we also recognise your charger by the serial number it sends along.
Download the Joulo firmware file
Every NG needs this, also when Joulo is already among the Back office presets: that preset only fills in the URL, the certificate is not part of it. It is a security certificate, packaged as a firmware file: you upload it through the firmware screen, but your charger's own software is not replaced. It tells the charger our server can be trusted. Save it on the device you will set up from • your phone or your laptop.
Open MyEve and connect to your charger
Your phone is on the same network as your charger. Can't manage that? Switch the charger off at the breaker for 20 seconds: it then broadcasts its own WiFi for a quarter of an hour, which you join from MyEve. Sign in with your ACE number and the password from your password card. Does MyEve offer a firmware update? Run it first • older firmware is missing the settings you need next. Unplug the car before you start: a charger that is charging can refuse the certificate and the OCPP settings.
Upload the firmware file (Basic tab)
Open the Basic tab, find the Firmware block, tap More options and then Browse files. Pick the joulo_alfen.fwi file you downloaded and wait until the charger restarts. This is a security certificate packaged as a firmware file: your charger's own software is not replaced. Do this step even when Joulo is already among the Back office presets • without the certificate the charger cannot trust our server.
Alfen on firmware updates via MyEvePoint the back office at Joulo (Advanced tab)
Open the Advanced tab, pick Back Office and go to the General tab. Is Joulo in the list? Pick it • the URL and the OCPP settings are filled in. Was your charger set to Standalone, that is now replaced by Joulo. Save and let the charger restart.
No Joulo in the list? Enter the settings yourself
Skip this step if you picked the Joulo preset. On that same screen you pick the manual settings instead of a preset. Set Protocol to OCPP 1.6 (JSON) and Security Profile to 0, and enter wss://ocpp.joulo.nl • nothing after it, your charger appends its own object number. Save and let the charger restart. Stuck in MyEve? The ACE Service Installer can always do it • pick that route above.
