The reev EMS allows for self-onboarding of static load management locations directly in the reev Platform. However, for dynamic sites—where external components such as energy meters, PV systems, or battery storage systems are integrated—a separate onboarding process is required.
It is important that all installed charging stations are fully integrated and compatible with the reev EMS.
Please note: Compatibility with the reev backend does not automatically guarantee compatibility with the reev EMS.
A complete and up-to-date list of supported hardware models can be found on our website in the Hardware Compatibility Table.
Step 1: Installation
The energy meter used to measure the building consumption and a Teltonika router used to connect it to the reev backend must be installed on site according to our Installation Guides.
Depending on the site setup, two installation variants are possible:
Router as data provider – The Teltonika router serves as the main communication gateway for the entire EV infrastructure.
Preconfigured charging stations – Each charging station communicates with the backend individually via LTE.
The reev EMS supports various connection options, including LTE and LAN. Our installation guides describe the most common configurations but are not exhaustive.
Remote configuration depends on our support team’s ability to access the Teltonika router via the Teltonika Remote Management System (RMS).
If the router is connected via LAN, ensure that the RMS option is enabled in the Teltonika settings.
If connected via LTE, this step can be skipped.
If suitable, existing metering hardware may be reused, provided it meets the requirements outlined in our Installation Guides and consists of compatible and already integrated devices listed in the Hardware Compatibility Table.
Important: While the reev EMS supports different types of energy meters, a Teltonika router is always required. It functions as the IoT gateway, reading Modbus TCP registers from the meter and securely transmitting data to the reev EMS backend – making it irreplaceable.
While various Teltonika RUT models are supported, we recommend the RUT241 as the best balance between performance and cost.
For additional guidance on how to onboard and enable further EMS features such as §14a compliance, external EMS connection, or PV system support, please refer to the corresponding guides in this Help Centre.
Installation Checklist
Before moving on to the next step, please verify that:
The energy meter is correctly connected to the router’s LAN port or to the switch where the router’s LAN port is connected.
Both the router and energy meter are powered on (green LEDs flashing).
The router’s WAN port is connected to the local network, or (if using LTE) the signal strength is at least three bars.
RMS connection is enabled in the Teltonika router administration settings.
Step 2: Charging Point Configuration
All charging points installed at the location must be configured using the reev Installer App.
This step is essential, as it allows the qualified electrician to:
Define the maximum permissible load for each connector.
Set the phase rotation of each connector.
This information enables the reev EMS to perform phase-accurate dynamic load management, ensuring the protection of all electrical fuses at the location.
During this step, the main fuse limit of the site can also be provided. This value may be adjusted later if required.
Once all charging stations have been configured in the Installer App, the EMS will store the data and automatically assign it to the corresponding stations upon onboarding in the reev Platform.
Step 3: Installation Protocol
As a final step, complete the reev EMS Installation Protocol and submit it to [email protected].
After submission, our support team will enable the EMS for the selected location within 3 business days.
The installation protocol requests crucial information such as:
Teltonika & SIM card credentials – used by our team for one-time remote access and configuration of the device, avoiding the need for on-site technician intervention.
Site topology details – including the distribution of fuses and subfuses, their respective limits, and the assignment of charging stations under each fuse.
⚠️ Warning: The topology information must be accurate and verified by a qualified electrician. Incorrect data may lead to infrastructure damage.
After the EMS is enabled, the reev support team will inform the customer.
The customer can then review and validate the configuration and performance of the EMS directly in the reev Platform under the Energy Management tab.
