Support and Integration of Not Yet Supported Assets

Learn how Last Mile Solutions verifies and integrates unsupported energy meters, chargepoints, and solar inverters with Edge.

Use this page to understand how unsupported energy meters, chargepoints, and solar inverters can be verified or integrated with Edge.

Energy Meters

Find the list of supported energy meters here.

If your energy meter does not exactly match a listed model, contact support so we can verify compatibility.

For unsupported energy meters, Last Mile Solutions can provide integration at no extra cost if all of the following conditions are met:

  • The energy meter provides the right protocols/interfaces for Edge
  • The meter model is commonly available on the market
  • The physical meter can be sent to our headquarters for integration

Expected timeline:

  • Integration: 1–2 weeks
  • Meter return: up to 4 weeks
Energy meter integration

AC Chargepoints

All AC chargepoints that support OCPP 1.6 over Ethernet should work without additional integration. Edge automatically adjusts the settings to optimize load balancing. Contact support if you encounter any issues.

DC Chargepoints

Edge supports DC charging stations and adjusts its load-balancing behavior to account for higher charging speeds. However, unsupported DC stations initially appear as AC stations and do not include DC-specific handling.

For a first-time DC station connection, we recommend remote assistance. The integration process typically includes:

  • Configuring the station as a DC station
  • Testing responses and adjusting for DC-specific behavior
  • Reviewing priorities and offline behavior

Future firmware updates will include specific DC models, which removes the need for remote integration for later installations of those models.

Chargepoint integration

Solar Inverters

Sunspec Inverters

If your inverter supports the Sunspec protocol, you can connect it directly to Edge. After installation, contact support so we can verify the connection and validate curtailment.

Non-Sunspec Inverters

To request integration, send the details of your solar to [email protected]. Remote integration requires an on-site Edge connection and validation against the main building energy meter. The typical timeline is 2–4 weeks after the connection is established.

Solar inverter integration

Stationary energy storage systems

Battery systems can be integrated into Edge with no extra cost.
(Integration with no extra cost requires the battery integration to be reusable for future use cases)

Battery systems integration process:

  • Request the interfacing documents from the manufacturer (Including Modbus map)
  • Send the documents to Last Mile Solutions to check if the integration is possible
  • Battery will be integrated remotely

For remote integration:

  • Direct support from the manufacturer has to be available
  • The Edge has to be both connected to the main energy meter and the battery
  • Last Mile Solutions needs permission to freely charge and discharge the battery for testing
  • Last Mile Solutions might need the credentials to login to the web-interface of the battery
  • The integration process may take up to 4 weeks. (From the moment the battery is connected, excluding installation, excluding delays on manufacturer support request)

Batteries with special features(Hybrid systems, battery systems with backup power) may take longer to integrate.

Integration with grid operators

Non-firm contracts where the grid operator can reduce the available capacity are becoming more common. The Edge controller is well suited to mange this dynamic limits and where well willing to implement the various standardized contract forms.

For integration time and conditions contact Last Mile Solutions support with your use case.

For non-standard/custom integrations our Modbus server API or Rest API can be used.
