Integrate the Reduxi Controller with the GARO charger via Ethernet or Wi-Fi, using the OCPP protocol. Reduxi's flexibility allows cost reductions of up to 30%.
1. Install GARO application
2. Connect to the Metron application on the EV charger
Follow the instructions on how to connect the EV Charger to WiFi or LAN connection:
2.1 Metron OCPP module
Once the EV charger is connected to the local WiFi or LAN network the OCPP configuration can proceed. Under the OCPP module information about the Unique ID of the charger can be obtained.
2.2 Metron OCPP module configuration
To establish a connection via OCPP communication files in the OCPP module of the EV-charger must be correctly configured.
The image below displays, how configuration must be done:
Station unique identifier must be defined as: /ocpp/1.6./json/efrend/Unique_ID --> obtained from point 2.1
OCPP backend hostname: ws://Reduxi_IP
OCPP backend port: 80
3. Configuration for OCPP communication between the Metron Charger and the Reduxi controller
3.1 Add device
First login to the local Reduxi configurator and add a new device by clicking on the 'Add device' button.
3.2 Select the device that would you like to add
Within the first step select basic settings:
- Select Device type: EV charger,
- Select Type: OCPP 1.6 - JSON,
- And define the name.
3.3 Communication channel for OCPP
Define settings for the communication channel as displayed below:
Device identifier must be defined as: efrend/station unique identifier
From the last field of the Communication Channel, the user can copy the IP of Reduxi in the upper example case ws://192.168.1.121 link to point 2.2.
3.3 Test communication
To ensure that OCPP communication is established, a communication test can be performed via the 'Test communication button' located in Menu Settings/Device/name_of_device in the lower right corner.
There are three different cases of communication response.
Case 1: Communication is working properly.
Case 2: Unable to communicate with device 1, the ID of the device is not set or is different.
Case 3: No device with OCPP 1.6 communication is found.
4.6 Default parameters
Fill in the advanced settings and choose the parameters shown in the image below. Settings can vary depending on location needs. Once you are done, click on the 'Done' button down right on your screen.
4.7 Readings from Device
The purpose of this point is to show how to check readings from the device. This is done under 'Device/Last measurement'.
Once the device is successfully added through the configurator, it can be monitored via the cloud application Reduxi.
